The Separate Water Supply with solenoid valve is necessary to feed the evaporator with softened or desalinated water and the cooling coil with phosphate-treated or tap water.
Interruption of the pretreated and cooling water when the storage tank is full.
Required water pressure to the evaporator > 1 bar, to the cooling coil > 3 bar.
Efficiency of the water still is reduced by approx. 10 - 15 %.
