New heat condensers for municipal utilities

After a construction period of three months, two new heat condensers have been shipped to a power plant in Augsburg (Bavaria). Each apparatus weighs 4.6 tons, has a heating area of 203 sqm and 24,000 kW power. As a heating element a fully welded hybrid tubular plate heat exchanger is used. Steam at a temperature of 160 °C is fed to the primary side, where it cools down to around 90 °C. Water is guided through the secondary side via cross-flow process and heats from 65 to 130 °C.

VAU shipped a 13 tons heating condenser to Hamburg

It took about half a year to complete the heating condenser for a power plant in Hamburg. But now the device has been lifted onto the low-loader in our plant in Heldrungen and sent on its way. The heat exchanger has a weight of 13.1 tons; is 4 meters high, 2.5 wide and 3.2 meters long. At its destination the condenser is used to prepare hot water for district heating. The apparatus has a heating surface of 565 m² and a capacity of 65.2 MW. The core of the device is a hybrid tubular plate package.

VAU Thermotech is investing six-figure amount in the expansion of quality assurance

With the new pressure and leak test facility for our brazed plate heat exchangers, we are increasing production efficiency, at the same time increasing quality assurance and making it easier for our customers and ourselves to trace our products. The new  device has two test chambers operated alternately. While the analysis of one device is still in progress, the second can be removed immediately after the test and replaced with a device that is still to be tested. In this way it is possible to roughly quadruple the test cycle.

Hybrid Heat Exchanger grants CO2 reduction

Four fully welded Hybrid heat exchangers for a fermentation residue evaporation plant of an East German manufacturer of biofuels were certified by TÜV Süd inspectors. Our plate heat exchangers are compliant with the Pressure Equipment Directive (PED - 2014/68/EU). Usually, fermentation residues still contain a high amount of water which will be squeezed by our fully welded Hybrid heat exchangers. With the support of our heat exchangers these fermentation residues are made usable for a further processing stage. The result: additional CO2 reduction and a better energy balance. A special feature of this construction are the removable covers for cleaning purposes.

New innovation hotspot in Munich

After we relocated our factory from Munich to Thuringia in January 2015 we only had a small office in Munich. With now almost 240 square meter office we shine in Munich in new splendor! The office is located near the Munich trade fair in Riem and is optimally connected in terms of transport. "In order to create closer customer proximity in southern Germany and South-Europe we decided to open a new office with new modern business and conference rooms. For our existing and prospective customers in southern Germany travel times for training or product presentations are shortened, ”says the CEO, Osama Nasser. The new office should serve as an innovation hotspot for the development of new products.
