BlueSea Technology AS, Norway

The Wieland Group establishes a JV for the marketing of brass nets and more for aquaculture

For the development and marketing of brass nets and cages, Wieland-Werke AG has formed the “BlueSea Technology AS” joint venture with Lerow AS in Norway. The partner has the respective know-how as well as longstanding experience in the field of aquaculture. Daniel Steitz, Wieland-Werke AG (60% JV), is the CEO, and Svein Jarle Midtøy, Lerow AS (40% JV), the COO of BlueSea Technology AS.

The world’s rising population has created an increase in demand for food. Fish is an important and healthy food source. The increasing demand leads to overfishing of the world’s oceans. Aquaculture enables the controlled farming of fish. The growth rates of this market are approx. 7% per year. Today, the largest markets for maritime aquaculture are Norway and China.

For aquaculture, specifically for the fish cages used, Wieland has developed a wire and subsequently a brass net made of the alloy Wieland BlueSea® SE1 which offers many advantages over conventional nylon nets. Wieland has thereby extended its value chain to include the weaving of nets which enables the company to manufacture and market complete aquaculture cages. To this end, Wieland has invested in a new weaving line with a weaving width of up to 12 meters at its location in Vöhringen.

The products for aquaculture are brought together under the BlueSea® brand. Aquaculture cages made of BlueSea® Mesh have a significantly longer service life than conventional nets. High mechanical strength offers very good protection of fish against predators and the net retains its form even in stronger currents and stormy weather. Brass stays naturally clean in sea water what considerably reduces cleaning effort. This in turn leads to a significant reduction of stress in fish, as interference with their habitat becomes less necessary. At the end of the net’s service life, the material is 100% recyclable, which is another advantage over nylon nets. In summary, the use of Wieland BlueSea® results in healthy fish from environmentally friendly, sustainable aquaculture with a considerably lower carbon foot print as compared to conventional nylon cages.

Fiscal year 2015/16: net income significantly above the previous year

Current fiscal year: moderate growth expected

In the fiscal year 2015/16 (1 October 2015 to 30 September 2016), the sales quantity of the Wieland Group rose by almost 5 per cent over the prior year to 464,000 tonnes. Sales fell by 8.5 per cent to 2,547 million euros (previous year: 2,784 million euros) as a consequence of lower metal prices. Net income for the year was 64 million euros (previous year: 48 million euros).

The significantly improved result was particularly due to higher sales quantities, a superior-grade product mix as well as cost reductions. Foreign currency developments also had a favourable effect.

Uneven demand

In the fiscal year 2015/16, there was a modest recovery of the global economy, though with regional variations. Demand for products of the Wieland Group was, therefore, uneven. Slackening growth in China had a dampening effect. Business in Europe was still hampered by the continuing conflicts in the Middle East and Eastern Europe. Thanks to the slight upturn in the US economy, demand from North America proved stable.

After a disappointing first quarter, demand for Wieland products picked up noticeably in January 2016 and remained strong through to the end of the fiscal year, particularly due to the positive trend in the automotive sector.

The increase in sales quantities was mainly driven by value-added products for applications to reduce fuel consumption and emissions. The ongoing trends toward miniaturisation and enhanced energy efficiency bolstered demand for high-performance alloys, particularly for vehicle electronics. Project business with products for the petrochemical industry suffered considerably from continuously low oil and gas prices.

Declining metal prices

At 4,300 euros per tonne, the average price of copper was 17 per cent down on the previous year’s value. The average price of zinc was 1,690 euros, 7 per cent below the prior year’s level.

Capital expenditure

In the fiscal year 2015/16, the Wieland Group invested a total of 70 million euros in tangible assets (prior year: 65 million euros). Of this, Wieland-Werke AG accounted for 30 million euros (prior year: 40 million euros). The investments focused on the German locations Langenberg and Vöhringen, and on the foreign companies Wieland Metals, USA, B. Mason & Sons, UK, and Buntmetall Amstetten, Austria.

Employees

In the fiscal year 2015/16, an average of 6,658 employees (prior year: 6,780) were working for the consolidated companies of the Wieland Group, with Wieland-Werke AG accounting for 4,252 (prior year: 4,357).

Dividends

At the annual general meeting of Wieland-Werke AG on 17 March 2017, a dividend in the amount of 15.5 million euros was declared (prior year: 12.4 million euros).

Current fiscal year

In the current fiscal year, the healthy demand for Wieland products recorded during the course of 2016 is continuing, and there are currently no signs of an imminent change. However, specific factors of uncertainty have remained, such as the trouble spots Russia/Ukraine and the Middle East. Political changes in Europe and in the USA also have to be considered, notably Great Britain's Brexit decision and potential protectionist tendencies in the USA. Against this background, development of the sales quantity is expected to be comparable to that of the previous year.

Wieland-Werke AG: Change in the Chairmanship of the Executive Board

With effect from 1 April 2017, the Supervisory Board of Wieland-Werke AG has appointed Dr. Erwin Mayr as Chairman of the Executive Board of Wieland-Werke AG. He succeeds Harald Kroener who will retire effective 31 March 2017. Dr. Mayr has been a member of the Executive Board of Wieland-Werke AG since 1 January 2017.

For more than 45 years, Harald Kroener has been working for the Wieland Group in different positions both in Germany and overseas.

Wieland Thermal Solutions at the ISH 2017: Efficient heating of drinking water and recovery of heat from greywater with the “GEWA-safe” safety tube

Ulm – 9 February 2017 – The focus is on efficient heating of drinking water and recovery of heat from greywater when the “Wieland Thermal Solutions” brand presents thermal engineering solutions at the stand of the Ulm-based company Wieland-Werke AG at the ISH 2017.

For the efficient heating of water in heat-pump systems, Wieland Thermal Solutions recommends direct condensation in which domestic water is heated directly in the storage tank by means of a double-wall heat exchanger. Through direct contact with the water in the tank, the heat exchanger requires the smallest temperature differences and heat losses are avoided. The double-wall finned tube of the WRKS heat exchanger also ensures that drinking water is effectively protected against contamination in the event of damage. The GEWA-safe safety tubes are based on a double-wall tube solution. Through a leakage gap it allows leakages in the heat exchanger to be instantly detected. The safety solution, therefore, also meets the requirements of drinking water protection according to DIN EN 1717 for heat-pump systems.

In the field of heat recovery, GEWA-safe tubes also ensure the necessary protection with, at the same time, energy-efficient operation. Heat recovery systems are particularly suitable where energy, which has already been used for heating, can be used for a further process, for example for domestic hot water. When heat is recovered from shower water, energy is extracted from the hot, effluent shower water in order to heat incoming cold water. The safety tube offers the highest thermal conductivity, even in bent condition, due to the material copper combined with optimised design. Connections and the exact design are agreed on an individual basis.

In addition, Wieland Thermal Solutions presents medium-high finned GEWA-D copper tubes for making heating water and solar thermal systems more efficient. For the design of lightweight and compact gas-fired boilers the high-finned GEWA-H tube made of aluminium with its large surfaces is showcased.

Wieland-Werke AG at the ISH 2017: copper tubes for the supply of drinking water, heat and cold – hygienic and energy-efficient

Energy-efficient supply of heat and cold as well as hygienic supply of drinking water are the central trade fair themes of Wieland-Werke AG at the ISH also this year. The Ulm-based manufacturer of copper tubes and copper materials presents its respective current product portfolio in Frankfurt. Regarding underfloor and panel surface heating, the focus is on the cuprotherm system with the new, ultralight “ekoLight” structure. In the field of pre-insulated refrigeration tubes, Wieland also offers new dimensions, thus rounding off its product spectrum as a full-range supplier. Wieland customers also benefit from the new service functions on the website www.wieland-haustechnik.de which is also presented. This website includes, among others, an online “system finder” for the first time from March 2017 enabling architects, planners and installers to easily choose a solution from a large number of cuprotherm floor structures. In the field of drinking water supply, Wieland presents the entire SANCO and WICU copper tube programme. For industrial manufacturers, experts in heat exchangers and fittings materials are also available at the ISH: Besides the lead-free premium alloy CUPHIN, Wieland presents its wide range of drinking water alloys which are all on the Federal Office of the Environment (UBA) hygiene list. The transitional regulations concerning the use of the positive list will expire in April 2017. After that the positive list for metallic materials will be applicable and legally binding.

For energy-efficient surface heating with the cuprotherm system on the basis of copper tubes, Wieland presents the extended portfolio as well as an additional system structure: the thin-layer and ultralight cuprotherm “ekoLight”. The current portfolio includes system components for underfloor and panel surface heating, drinking water installation and radiator connection. There are also a number of innovations regarding control systems. Here, Wieland offers new analogue and digital room thermostats such as a WLAN-capable control module for control also via smartphone. The new version of the cuprotherm planning software is also presented. With the online “system finder” on the redesigned homepage customers can choose the suitable system structure from more than 50 variants.

In the field of air conditioning and refrigeration applications Wieland exhibits pre-insulated refrigeration tubes in additional dimensions. Another product on show is the innovative K65 high-pressure tube system. Based on the high-strength copper alloy K65, the system consisting of K65 tubes and K65 solder fittings is suitable for applications with operating pressures of up to 120 bar. It is, therefore, particularly suitable for use as high-pressure piping system for CO2 as an environmentally friendly refrigerant. Last autumn already, the K65 system was complemented by an additional dimension.

Regarding alloys for fittings, Wieland focuses on the lead-free premium sanitary material CUPHIN. The portfolio comprises various other drinking water alloys, in particular AQCUARIN which is suitable as a follow-on alloy for CW602N. All Wieland sanitary alloys meet the requirements of the UBA hygiene list, which will be legally binding as from April 2017, and are included in this list.

By engineers for engineers – Wieland Thermal Solutions reissues the Heat Transfer Data Books

For many years, the Heat Transfer Engineering Data Books have been a standard reference in thermal engineering. They provide both a comprehensive basic knowledge and detailed insights into heat transfer engineering – a valuable resource for engineers in research and industry as well as for thermal engineering university students.

The revised first volume, the so-called Heat Transfer Data Book II, had originally been compiled by the engineers K.J. Bell and A.C. Mueller from Wolverine Tube Inc. On 280 pages, it summarises the fundamentals of heat transfer, from sensible heat transfer and condensation via the use of Trufin tubes in air-cooled heat exchangers through to the optimisation of evaporation processes by using low finned Trufin tubes.

The author of the Heat Transfer Engineering Data Book III is the leading heat and mass transfer scientist Prof. John Thome at the École Polytechnique Fédérale in Lausanne, Switzerland. The book comprises 673 pages as well as almost 200 short film sequences and an Excel calculation tool and describes enhanced heat transfer design methods for shell-and-tube heat exchangers. It covers design considerations for enhanced heat exchangers, single-phase shell-side flows and heat transfer, heat transfer to air-cooled heat exchangers, condensation on external surfaces, condensation inside tubes, boiling heat transfer on external surfaces, two-phase flow pattern, falling film evaporation, thermodynamics of refrigerant mixtures and refrigerant oil, post-dryout heat transfer, flow boiling and two-phase flow of CO2 as well as two-phase flow and boiling in microchannels.

The rights for these publications have since recently been with Wieland-Werke AG. Wieland Thermal Solutions specialises in solving various thermal engineering problems. As a thermal engineering expert, Wieland Thermal Solutions has reissued the books in a modern form as e-book (pdf) and made them again generally available. The English books can be ordered from a German and a US-American online bookstore.

Exchange with Professionals of the Petrochemical Industry at the AIChE Spring Meeting

Fiscal year 2014/15: lack of demand stimuli

Current fiscal year: moderate growth expected

In the fiscal year 2014/15 (1 October 2014 to 30 September 2015), Wieland Group sales rose by 0.4 percent year-on-year to 2,784 million euros (previous year: 2,772 million euros). At 443,000 tonnes, the sales quantity was 4.7 percent down on the prior-year level (previous year: 465,000 tonnes). Net income for the year was 48 million euros (previous year: 31 million euros).

Lack of demand stimuli

There was no noticeable recovery of the global economy in the fiscal year 2014/15, so the stimuli needed for a revival of demand for products from the Wieland Group failed to materialise. Against this background, incoming orders and sales quantities remained below the prior-year levels.

Result influenced by special factors

The lower quantities sold compared to the previous year burdened the result. However, this fact was more than offset by a higher-grade product mix and cost reductions. The result was bolstered beyond this by special factors such as exchange rate gains resulting primarily from the weakening of the euro against the US dollar. Falling raw materials prices in the second half of the fiscal year and corresponding effects from accrual accounting and the booking of an insurance payout to cover the fire-induced loss at the Vöhringen location had an additional positive impact.

General trends

One reason for the declining trend was the slackening growth in China, which had a negative impact on the economic situation across the Asian region. In addition, business in Europe was affected by the conflicts in the Middle East and in the Ukraine. Conversely, borne by the robust domestic economy, demand in the North American market was stable.

On the whole, demand from the automotive industry improved, although incoming orders showed a significant decline during the last quarter of the fiscal year. Demand for products for electrical and electronic applications was stable, whereas demand from the machine manufacturing, construction equipment and hydraulics industries continued its declining trend.

Capital expenditure

In the fiscal year 2014/15, the Wieland Group invested 65 million euros in tangible assets (prior year: 72 million euros). The emphasis was on replacement investment at the German locations in Langenberg, Vöhringen and Ulm as well as at the companies in the USA and the UK.

Employees

In the fiscal year 2014/15, an average of 6,780 employees (previous year: 6,790) were working for the consolidated companies of the Wieland Group, with Wieland-Werke AG accounting for 4,357 (previous year: 4,365). With the acquisition of Metallschmelzwerk Ulm GmbH, 39 employees joined the Wieland Group.

Dividends

At the annual general meeting of Wieland-Werke AG on 18 March 2016, a dividend in the amount of 12.4 million euros was declared which corresponds to the value of the previous year.

Current fiscal year

Due to the slowdown of growth in China, incoming orders showed a noticeable decline in August 2015. Products for the automotive sector as well as for electrical engineering and communications technology were particularly affected. This led to capacity underutilisation at Wieland-Werke AG in some cases from October to December 2015. Demand has noticeably improved since January 2016, with good capacity utilisation currently being recorded at all locations.

Outlook

The economic scenario continues to be difficult. Demand is still affected by the slowdown of growth in China and the crises in the Ukraine and in the Middle East.

Against the background of waning global economic growth, sales quantities and net income for the fiscal year 2015/16 are expected to show a moderate increase with values slightly up over the previous year.

Buntmetall Amstetten is showing smooth tubes made of cupronickel-10 (CuNi10) and cupronickel-30 (CuNi30) not only in lengths but also in coil format, for e.g. heat exchangers for sea water applications and oil coolers. Thanks to the coil format, the customer is very flexible and able to produce tubes of different lengths without a lot of scrap from the coil. Bare and coated Frigotec cooling tubes for refrigeration and air conditioning installations will also be presented.

In the field of materials for drinking-water components, e.g. fittings, ball valves, etc., the Business Group Extruded and Drawn Products for the product group ‘Machining Brass’ is showing a broad, innovative and reliable portfolio of hygienically approved alloys, including ECOBRASS. With ECOBRASS, lead-free, safe and economical installation is possible already today. Besides ECOBRASS, AQCUARIN is another dezincification-resistant material available to replace the hygienically critical material CW602N. Since January 2016, AQCUARIN has been officially listed as a hygienically suitable material.

2.5 million euro investment: Wieland-Werke AG develops an energy-efficient casting line – funded by the Free State of Bavaria

Lost-foam casting enables more efficient production of complex copper components.

How can complex-shaped copper components be manufactured economically and energy-efficiently? And how can energy be saved along the entire process chain and particularly during casting? These questions are addressed by Wieland with the EnerGuss project. Based on lost-foam casting, Wieland, as a manufacturer of copper semi-finished products located at Vöhringen/Bavaria, has commissioned a new research facility in order to produce test components and small-series quantities. A total of 2.5 million euros are invested in the three-year project, with approx. one million euros being funds from the Free State of Bavaria. The facility is not only intended for energetic research. It is also available to Wieland customers and other interested partners from the industry for the manufacture of prototypes and small series quantities. “With the experimental plant, we want to develop recipes and processes in order to manufacture complex-shaped components fast, cost-efficiently and resource-efficiently”, says Dr.-Ing. Uwe Hofmann, head of New Product Lines at Wieland. The goal of the research project is to reduce energy consumption during casting by 20 % with the newly developed, resource-conserving production concept. After successful completion of this pilot plant phase, expansion of production is conceivable if the corresponding demand warrants it. Wieland is one of the world’s leading manufacturers of copper and copper-alloy semi-finished products with a history of almost 200 years and expertise in metal processing.

With lost-foam casting, it is possible to manufacture components with complex geometries much more efficiently than using conventional methods. Wieland is currently one of the few industrial processing companies offering lost-foam casting, the so-called “casting with lost-foam patterns” in connection with copper alloys. It is a casting method with polystyrene patterns embedded in moulding sand that is free of binding agents. The pattern decomposes through the addition of liquid metal. The molten metal fills the resulting cavity for an accurate reproduction of the pattern geometry. With lost-foam casting, Wieland enables the manufacture of sophisticated copper components without costly secondary processing operations. A large number of applications are possible – from electrical engineering products of a few 100 grams through to machine components weighing several kilograms. The company mainly addresses developers and product designers.

 The new casting line, including upstream workstations, has been commissioned at Wieland’s main production location in Vöhringen, Bavaria. On approx. 900 square metres, test components are currently being manufactured in order to optimise the process itself as well as the material flow and the energy consumption of the individual operations. The aim is to manufacture near-net-shape components in order to reduce as much as possible the amount of material required. Here, the technological advantage of lost-foam casting plays a decisive role, since, unlike conventional methods, the near-net-shape component is proverbially made “in one casting” in the lost-foam casting process – without operations like forming or mating.

Lost-foam casting comprises of twelve operations: 1. Pre-expansion, 2. Foam pattern moulding, 3. Gluing, 4. Cluster assembly, 5. Coating, 6. Drying, 7. Moulding, 8. Pouring, 9. Cooling, 10. Demoulding, 11. Cleaning, 12. Separating and finishing. In the context of development partnerships, Wieland supports its customers in the design and realisation of complex-shaped components, as can be produced with lost-foam casting. Examples are guide bushings for special-purpose machines or outlet fittings for the sanitary industry.

Wieland-Werke AG at the ISH: Energy-efficient surface heating and heat transfer, hygienically first-class drinking water supply

Sanitary materials and piping systems for first-class drinking water hygiene – application-optimised heat exchangers – the cuprotherm umbrella brand presents itself with innovative system extensions and BVF quality seal.

At the ISH 2015 in Frankfurt, the Ulm-based company Wieland-Werke AG presents as a central theme the supply of hygienically first-class drinking water with its branded SANCO copper tubes as well as its sanitary alloys such as CUPHIN and AQCUARIN. SANCO tubes are now available with closed tube ends as standard, thus combining the hygienic advantages of the material copper with packaging that is specially designed to meet the requirements of drinking water hygiene. Regarding sanitary alloys, Wieland focuses on the lead-free premium sanitary material CUPHIN and the new material AQCUARIN. The latter is particularly suitable as a cost-efficient alternative to and follow-on alloy for CW602N. For energy-efficient surface heating with the cuprotherm system based on copper tubes, Wieland has extended the product family. The Ulm-based manufacturer presents, among other products, the cuprotherm.plan wall heating variant. Under the Thermal Solutions brand, Wieland also shows heat-transfer solutions for heat pumps, solid fuel boilers as well as hot water tanks and condensing gas boilers. These solutions feature customer- and application-optimised innovative heat-exchanger geometries characterised by efficiency, compact design and longevity.

The successful cuprotherm umbrella brand now comprises additional innovative solutions: At the end of 2014, the product range of the cuprotherm family has been extended in the fields of wall heating and installation systems. The current portfolio includes new system components for drinking water installation, radiator connection and, of course, surface heating. New are the flush-mounted cuportherm.plan wall heating register as well as control components and system tools. Wieland also presents its newly available supplements to the 33 mm thin-screed ekoBoden variant. The modern CTX installation system based on flexible copper tubes for drinking water applications now also comprises CTX ball valves with an adapter. By offering this comprehensive system range, which is now available under the cuprotherm umbrella brand, Wieland makes it easier for all its partners in design, trade and craft to choose the suitable system solutions for heating, sanitary as well as floor, ceiling and wall surface heating applications.

All drinking water tubes and materials presented at the ISH are on the list of “metallic materials hygienically suitable for drinking water” of the Federal Environmental Agency (UBA). The branded SANCO copper tube, which is universally suitable for high-quality drinking water, heating and gas installations, has been supplied with closed tube ends since 1 January 2015. Based on this special format as well as the material properties of copper, SANCO meets the highest hygienic standards which exceed the usual requirements. Wieland thus meets the requirements of the market. The new SANCO variant is also promoted by the German Sanitation, Heating and Air Conditioning Association (Zentralverband Sanitär Heizung Klima) under the “Handwerkermarke”.

Since 2014, Wieland has with AQCUARIN (CW725R) a new sanitary material in its programme which is particularly suitable as a follow-on solution for the dezincification-resistant brass (CW602N). Wieland thus rounds off its portfolio of drinking water alloys, which is led by the lead-free CUPHIN (CW724R) brand.

For the safe heating of heating and drinking water, the double-walled WRKS safety heat exchanger offers particular protection of water against contamination by refrigerants.

From its field of industrial tubes, Wieland presents the K65 high-pressure tube system. Based on the high-strength copper alloy K65, this system is designed for applications with operating pressures of up to 120 bar and is particularly suitable for use as a high-pressure piping system CO2 – as an environmentally friendly alternative to conventional refrigerants.

Fiscal year 2013/14: high demand in the first, low demand in the second half

Fiscal year 2013/14: high demand in the first, low demand in the second half

Currently: dampened expectations

In fiscal year 2013/14 (1 October 2013 to 30 September 2014), Wieland Group sales fell 2.3 percent to 2,772 million euros (previous year: 2,837 million euros). At 465,000 tonnes (previous year: 449,000 tonnes), the sales quantity was 3.6 percent up on the prior-year level. The result was 31 million euros (previous year: 46 million euros).

Unsatisfactory demand

In a scenario of difficult economic conditions around the globe, the Wieland Group recorded an unsatisfactory demand in fiscal year 2013/14. While demand was still high in the first half of the year, the level of incoming orders decreased substantially from the second half of the year onwards.

Metal-related decline in sales

The decline in sales resulted from the metal prices that were lower compared to the previous year. At 5,200 euros per tonne on average, the copper price was 10 percent down on the prior-year level.

Economic conditions

The geopolitical situation with flashpoints in the Middle East and Ukraine had an overall negative effect on demand. This was particularly true for the countries of Europe where there were no signs of a sustained economic recovery. Trends in the Asian markets varied. Although less dynamic, China has remained the growth motor in the region. Borne by stable domestic demand, business activity in North America continued on its positive trend. Considerable stimulation of demand for Wieland products came from the automotive and vehicle construction industry as well as the electrical and electronic sector.

Result

The result fell short of expectations. One reason for this was the fierce competitive and price pressure in the semi-finished products industry. In addition, decreased demand and poorer capacity utilisation in the second half of the fiscal year diminished the result.

Capital expenditure

In fiscal year 2013/14, the Wieland Group invested approx. 72 million euros in tangible assets (prior year 44 million euros). Capital investment focused largely on individual measures at different locations. The main purpose of these investments was to improve infrastructure, modernise production technology, boost productivity and also cut energy consumption.

Employees

In fiscal year 2013/14, an average of 6,790 employees (prior year 6,680) were working for the consolidated companies of the Wieland Group, with Wieland-Werke AG accounting for 4,365 of these (prior year 4,300). The increase is largely due to additional staff at Wieland-Werke AG as well as at the subsidiaries in Austria and the USA.

Dividends

At the Annual General Meeting of Wieland-Werke AG on 6 March 2015, a dividend in the amount of 12.4 million euros was declared which corresponds to the value of the previous year.

Dampened expectations

In the current fiscal year, which started on 1 October 2014, demand continues to be subdued. This particularly holds true for Europe which is partly in recession. The other two sales regions America and Asia are growing only slowly, with impetus for growth only coming from the USA. Strong demand is mainly recorded for products for the automotive industry and energy-efficient applications in machinery and plant construction.

Against this background we expect the result to be slightly up on the prior-year benchmark.

Wieland Thermal Solutions with a focus on safety tubes and system efficiency at the ACHEMA 2015

At the ACHEMA in Frankfurt from 15 to 19 June 2015, Wieland Thermal Solutions will be presenting its GEWA-safe double wall safety tubes in hall 5.1 at stand D54.

The GEWA-safe tubes (practically a tube-in-tube solution) feature defined leakage paths between the inner and outer tube for the absolutely reliable separation of fluids, e.g. reactive, hazardous or explosive fluids, without the need for additional circulation (closed loop intermediate fluid). This ensures highest system availability, efficiency and safety, as damage to inner or outer tube is immediately recognisable and can be fixed as part of regularly scheduled maintenance. The excellent thermal contact of the two tubes results in outstanding heat transfer without additional heat transfer fluid. GEWA-safe tubes enable the manufacture of very compact heat exchangers, thus reducing material costs and fill levels. Depending on the desired application, the tubes are available with either smooth or profiled surface in copper, cupronickel and stainless steel. The safety tubes are used, for example, in the pre-heating of fuel gas for gas turbines, for the protection against environmentally harmful and toxic substances, for the isolation of heat transfer oil in transformer stations and for drinking water protection according to DIN EN 1717 in heat-pump systems. They are also used in so-called safety heat exchangers for highest standards regarding system safety in chemical processes, for example in the production of polysilicon.

In addition, Wieland Thermal Solutions will be presenting current solutions for system efficiency increase in the oil, gas and petrochemical industries as well as in the power generation industries. GEWA-PB tubes have in the meantime proved successful in ethylene and liquefied natural gas production. They enable a compact design of heat exchangers. The surface structure of the tube enhances the effect of nucleate boiling, thus intensifying the evaporation process. For the different requirements regarding thermal conductivity, mechanical properties and corrosion resistance in the oil and gas processing industries, Wieland Thermal Solutions will also be presenting at the ACHEMA its portfolio of low-finned tubes in a wide range of materials. GEWA-K, GEWA-KS as well as Trufin S/T and Turbo-Chil tubes are manufactured in the materials carbon steel, stainless steel and titanium. They are mainly used in coolers, preheaters, condensers and evaporators to achieve savings in both the equipment as well as the overall plant design, for example regarding plot layout, liquid inventory, piping, racks and foundations.

New heat exchanger technology for air-cooled liquefied natural gas facilities (LNG): DIESTA

GEA Batignolles Technologies Thermiques and Wieland Thermal Solutions, in partnership with Technip, invite you to discover their new DIESTA heat exchanger technology for air-cooled LNG plants, at the World Gas Conference 2015 to be held in Paris from June 2 to 5, 2015.

GEA Batignolles Technologies Thermiques, Wieland Thermal Solutions, and Technip have developed a new technology to boost efficiency for air-cooled liquefied natural gas (LNG) facilities: DIESTA, short for “dual internally and externally structured tube for air-coolers.” DIESTA is a combination of two established technologies for the outside and inside of a tube, the key component of an air-cooler. For this development, the EPC company Technip and Wieland Thermal Solutions, specialists in heat transfer, have been associated with the air fin cooler and heat exchanger experts GEA Batignolles Technologies Thermiques.

DIESTA technology typically allows increase in LNG production by 2 to 3 %, while taking advantage of compression power savings. Moreover, the equipment footprint can be reduced by up to 20 % due to a more compact design. Finally, the reduction in specific fuel gas consumption lowers CO2 emissions.

The consortium has chosen the World Gas Conference 2015 in Paris to formally launch its new technology. A presentation will take place during the Gas Processing Interactive Session on June 4, and specialists from these three companies will be available at their respective booths (J36B for GEA BTT and I18 for Technip) to welcome and inform LNG specialists about their innovation.
