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.

VAU gets the steam up

Delivery and installation of worldwide unique six-stage hybrid plate heat exchanger completed in record time. After just 13 months production time, it’s done: Six hybrid plate heat exchangers each with 1,110 square meters heating surface and 19 tons each as well as additional pressure vessels were delivered completely and on time to a sugar factory based in southern Germany. Thanks to the precise planning by VAU Thermotech all equipment and containers were installed within a few hours after they had been delivered to the customer.

The customer decided to choose our compact Hybrid plate falling film evaporator because of limited space and for the process itself which is the gentle evaporation of Palatinose™, obtained from conventional sucrose (household sugar). Our Hybrid Heat Exchanger combines the advantages of a shell & tube with those of conventional plate heat exchangers resulting in more compact design. VAU Thermotech took over the entire project management, such as preparation of a factory balance sheet, design of all apparatus, engineering services, coordination of an engineering office and a container manufacturer, entire commercial processing, overall planning of the steel construction in the boiler house, planning of the installation on site and the complete delivery logistics. The heart of the entire plant consists of 6,480 square meters evaporator surface which were manufactured in our own factory as fully welded plate packs made of stainless steel.

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. The appreciation especially towards the Austrian and southern German market was the motivation for this step. For our existing and prospective customers in southern Germany travel times for training or product presentations are shortened, ”says the CEO of VAU Thermotech GmbH & Co. KG, Osama Nasser.

The new office should serve as an innovation hotspot for the development of new products. We offer motivated applicants a solid perspective.

Effective corrosion protection coating for brazed plate heat exchangers

Modern heating systems are accompanied by the treatment of heating water to avoid undesirable calcifications. The water treatment according to VDI 2035 specifies demineralized or softened water for heating systems. The so-called deionized water (fully demineralized water) increases the probability of corrosion for the essential component of the system - the copper-brazed plate heat exchanger. 

VAU Thermotech has developed an effective corrosion protection coating for copper-brazed plate heat exchangers together with a cooperation partner which prevents detaching of metal ions and guarantees resistance to demineralized water.

This innovative solution offers the advantage that water which is not in the range for copper-brazed plate heat exchangers can also be used.  Our entire brazed product range is available with anti-corrosion coating. There is no need to rebuild the existing connections when switching to a corrosion protection coated heat exchanger. The new type of heat exchanger smoothly fits in the existing system.

We proudly present cost-optimized efficient coated stainless steel plate heat exchanger without non-ferrous metals.

Next big order from the sugar industry

As we shipped three plate evaporators to a northern German sugar factory in 2018, we were awarded a major contract this year for the manufacture, supply and engineering of a complete palatinose evaporation station.

In particular, we have prevailed here due to the more compact design of our hybrid evaporator against the classic tube bundle evaporator. The operator of the system benefits from the known advantages of our hybrid heat exchanger: Thanks to the significantly more compact construction of the evaporator, the space saved is used to increase the necessary heating surface. Due to the better k-value and the larger surface, the productivity can be increased and/or the energy requirement to be applied can be greatly reduced.

Südzucker/BENEO-Palatinit has developed a process for obtaining Palatinose™ from table sugar (sucrose) for use as a functional carbohydrate. Application finds Palatinose™ as functional carbohydrate in sports and wellness drinks, sports nutrition and in the clinical nutrition.

Official & successful acceptance test of our three plate falling film Evaporator at Nordzucker

As we already reported in May 2018 the three plate evaporators supplied by VAU Thermotech with a total heating area of ​​12,000 m² were successfully installed at Nordzucker. The campaign in the sugar factory started on September 18th, 2018 with 18,000 tonnes of sugar beet processed per day. Our evaporators were successfully subjected to final acceptance test at November 15th, 2018 after 56 days of continuous operation and approx. one million tonnes of beet processing. For all three evaporators, the guaranteed parameters could be proved and even exceeded. By investing in the new evaporation station, about 10 tons of steam per hour are saved during operation. This considerable energy saving can significantly reduce the payback period. VAU Thermotech would like to thank all those involved for this successful Project.
