Expansion and Heat Recovery Module EHM
The module recovers a large proportion of the heat from the hot water (waste water/condensate) in the boiler system. The expansion tank serves to permit the expansion of pressurised water. The expansion steam produced in this process contributes to heating the feed water tank. In the down-line heat exchanger, the make-up water in the boiler system is preheated and the desalinated water/condensate is cooled to a temperature of approx. 35 °C.
