Wieland WRKS Double-wall Heat Exchanger
2017/07/15
With direct condensation in the hot water tank of the domestic hot water heat pump, Wieland Thermal Solutions offers a heat exchanger which is particularly cost-effective, energy-saving and low-maintenance.
 
Unlike, for example, the wrap-around solution, the WRKS double-wall heat exchanger operates with minimal temperature differences due to direct contact with the water in the tank. As a result, heat loss is prevented. As the heat exchanger is immersed in the water tank, it can be positioned in the cold region for better effectiveness with peak coefficient of performance (COP) values according to EN 16147.
 
The double-wall GEWA-safe tube indicates any leakage through the standard-compliant leakage gap, thus preventing cross-contamination. The finned surface of the tube allows for very compact design and a significant reduction in refrigerant volume - up to 60%. Compared with previous models, reductions in material costs can reach up to 40%.
