The heart of every heat pump – our revolutionary condenser EXL 5 for R 290

Our EXL 5 was specially designed for the use of the refrigerant R 290. R 290 is a natural, ecological refrigerant that also offers safety because it is non-toxic. Our new EXL 5 refrigerant condenser for your heat pump, optimized for you, is here! Our entire team - from development to production - enjoyed seeing how the product developed. Your advantages: Thanks to the optimized structure, the heat exchanger has a low filling volume. This saves material and reduces weight at the same time. Visit our booth at the IFH in Nuremberg and experience our product highlight live in Hall 3A, Stand 3A-210.

VAU Thermotech GmbH & Co. KG is a partner of the Kulturgut Zuckerfabrik Oldisleben Foundation

VAU Thermotech GmbH & Co. KG has been a manufacturer and supplier of fully welded plate evaporators for European sugar factories for years, based in Heldrungen, Thuringia. The owner, Mr. Osama Nasser, and his CTO, Mr. Manfred Herrmanns, are proven experts in the sugar industry. At the foundation's request, Osama Nasser therefore agreed without hesitation to support the cultural asset of the Oldisleben sugar factory, which is located just a stone's throw from his factory. “For us, as a supplier to the sugar industry for decades and in immediate vicinity, it is a very special honor to support the cultural asset Zuckerfabrik Oldisleben and thus honor the historical monument accordingly.” Dr. Martin Bruhns, managing director of the foundation, is pleased about the first funding commitment from industry: “It is an important milestone for the future of the foundation as it is the first commitment from industry.”

Steam converter in successful trial operation

Last summer we delivered two steam converters with a heating area of ​​1,788 m² per unit and two preheaters with  ​​337 m² per unit to a power plant in Brandenburg. The devices used as auxiliary steam generators serve to separate the system and are intended to protect the turbine blades from corrosion caused by sodium hydroxide. The steam converters each weigh 33 tons, have a total output of 58.4 MW each and generate 90 t/h of clean steam at a nominal load of 100%. The installation of both lines was completed in January 2024 and has already successfully entered trial operation. The calculated performance values ​​were exceeded.

Year-end rally – major order will be delivered on time before Christmas

Our heating condenser for a waste power plant plant in Bavaria is on its way. With an output of around 15 MW, the community of Weißenhorn is supplied with district heating - demand is increasing rapidly. In keeping with the energy transition, the bavarian district has decided on our effect-optimized hybrid plate heat exchanger, which replaces the tube bundle heat exchanger. Since the part-load behavior of our plate heat exchanger is much more favorable, our fully welded “hybrid” was deliberately chosen after a reference plant was even visited in Augsburg. We are confident about the year 2024 - another major order for a geothermal power plant will be shipped at the end of January and two carbo vapor condensers will go to Switzerland in the first part of the year.

VAU Evaporator sweeten your Christmas season

For decades, our Hybrid Tubular Falling Film Plate Evaporator has proven itself as a retrofit, especially in sugar factories. Compared to the classic tube bundle heat exchanger, our hybrid heat exchanger can achieve higher performance with a compact design, which reduces the use of material and lowers weight and manufacturing costs. We proudly announce that our evaporator retrofit with a heating area of ​​4,400 m² was successfully put into operation in a sugar factory in Baden-Württemberg in September 2023, just in time for the start of the campaign. The existing Robert evaporator was replaced by our much more efficient hybrid falling film plate evaporator with triple heating surface.

VAU Thermotech ensures good air around Swiss sugar factories

Air pollution control plays a very important role in Switzerland.
In order to further reduce NH3 emissions at the Swiss sugar factories in Aarberg and Frauenfeld, the carbonation vapors will each be cooled with a sophisticated fully welded hybrid tubular plate heat exchanger from VAU Thermotech in the near future.

VAU Thermotech: Co-designer of the energy turnaround

Hot water - or more precisely thermal water - plays a very important role for the operator of a geothermal power plant in Rhineland-Palatinate. As part of the GeoSmart Project funded by the European Union, "innovations to improve the flexibility and efficiency of geothermal heat and power supply systems" are to be investigated. VAU Thermotech is supplying four fully welded hybrid tubular plate heat exchangers for this purpose, which will be tested in running operation for functionality, durability and the possibility of complete cleaning.

VAU Thermotech on the road

Between March 13 and 17, 2023, we were delighted to present to numerous visitors from Germany, Europe and the rest of the world our new VAU COMPEX, a fully welded hybrid tubular plate heat exchanger. Traditionally, the ISH was immediately followed by the new product shows of Großhandels Contor GmbH (GC Group). In Munich, Cologne, Stutgart, Bremen and finally Berlin we presented selected products to an exclusive trade audience. We took the opportunity to get the latest industry news and to talk shop with the booth visitors.

VAU ready for take-off – Parts production for the aircraft industry

Traditionally, high quality is part of VAU Thermotech's corporate DNA. For years we have been certified for the aviation industry. Therefore, we were again commissioned to manufacture so-called domes - i.e. upper and lower parts for the waste water tanks of the Airbus A330. The domes are manufactured in a complex deep-drawing process in several production steps and finally subjected to a special quality check. Specially manufac-tured shipping crates are required for shipping, so that the packed domes can be safely delivered. So, next time you wash your hands on the plane and the water goes down the drain, think of us.
