High Performance Coaxial Condensers are distinguished by a special design of the flow path. Furthermore, the counter flow principle for improved heat transfer is applied. It permits an extensive exploitation of the superheat of the hot refrigerant vapour and a sub-cooling of the liquid refrigerant.
The superheated refrigerant vapour flowing in the free spave between the outer shell tube and the finned inner tubes cools down firstly and then condenses at the outside surface of the finned tubes. The condensate thus developed flows to the free space at the bottom of the system.
The cooling medium, e.g. the domestic or central heating water to be heated, flows in the inner tubes according to the counter-flow principle, whereby, together with the exploitation of superheat, high water outlet temperatures, possibly above the condensing temperature and a thorough sub-cooling of the condensate are obtained.
Design Working Pressure: Refrigerant Side 600 PSIG and Water Side 220 PSIG.
