• For water-cooled versions: The water regulating valve in the water outlet regulates the cooling
water flow.
When at partial or no load the dew-point pressure stays below the set-point, the regulator opens the
electronic hot-gas by-pass valve (208) to the evaporator circuit to prevent the evaporator
temperature from dropping below 0 ˚C (32 ˚F).
