GSWT®-heat exchanger

LOGO_GSWT®-heat exchanger
SEW® - Systemtechnik für Energierecycling und Wärmeflußbegrenzung - was founded in 1983 by engineer Heinz Schilling and has been lead by him as a managing partner ever since. Standing alongside him are authorised representatives Werner Bongartz - resort engineering, Rainer Janßen - resort administrator and Michael Schilling - resort sales. The company's goal is to market national and international patents and innovations for highly efficient and multifunctional energy-saving technology in ventilation and air conditioning systems. This as well as the significant developments of interconnected circuit systems serve to demonstrate the innovative nature of the company (1983 first plant with heat recovery efficiency of 80%, 1984 first integrated capabilities for multifunctional use, 1985 first DDC controls and 1986 first indirect evaporative cooling).

The basis of energy conservation is the newly developed counter-current heat exchanger layer (GWST®-Gegenstrom-Schicht-Wärmeaustauscher) and the resulting GWST®-technology. This heat exchanger technology makes the counter-current principle feasible and economical. Exchange temperature rates of up to 90% are achieved simultaneously for both media, which retains the value of the energy. The temperature exchange is due to an innovative arrangement of the heat exchanger surfaces in the counter current principle and the given temperature difference. The entire heat exchanger is constructed from a large number of functional heat exchange layer modules. This ensures on one hand easy installation, particularly for renovation and retrofitting, and on the other hand high redundancy and reliability. Furthermore, this design guarantees automatic venting of the heat exchanger.
The GSWT®-technology used successfully since 1984 for all heat transfer processes between water and air, particularly in air-conditioning technology. Other applications include natural cooling systems, re-cooling plants and air coolers/heaters.

The resulting heat recovery systems in the circulation system work with minimal energy consumption and are thus highly efficient. The efficiency was further increased when the systems were used multifunctional. 1984/85 the integrated reheating and sub-cooling was launched. In this process the circulatory fluid is post-conditioned and therefore the air-side heat exchanger can be dispensed with. 1986, saw the first use of indirect adiabatic evaporative cooling to improve the use of a heat recovery system in the summer months, additional features established on the market were for example pre-heating service water, free cooling, zone technology, dehumidifying cooling heat recovery, refrigeration re-cooling, solar heat, cool night use or integration of current-carrying CHPs. This makes efficiency values of 1:20 to about 1:100 possible, i.e. with 1 part electricity 20 to 100 parts of heat, cold and re-cooling is generated.  In 1998 SEW® was the first company awarded with the Faktor-4Plus prize by Prof. Ernst Ulrich von Weizsäcker. The amortization of such energy-saving systems is possible by the high energy savings in the shortest time. Due to the high redundancy of GSWT®-technology a multiple return on investment through cost savings in other buildings or structures is possible. In addition to highly efficient energy savings SEW® supports the high quality design of air-conditioning systems for a maximum of air quality and uses the GSWT®-technology to achieve reduced CO ² emissions.
