With the BEHNCKE counter-current principle, hot and cold water pass each other without any contact when heat is exchanged. This is made possible by specially manufactured smooth tube coils that can cope with a constant and therefore virtually loss-free operating pressure. The result is that the heat exchanger achieves the highest possible energy efficiency. BEHNCKE has incorporated this principle into several heat exchangers. The presentation of the individual models begins with the QWT 100.
- High-temperature heat exchanger with a stainless steel outer shell with a welded stainless steel tube coil
- The use of a smooth tube makes calcification almost impossible with regular maintenance on the primary side
