Evaporating Pressure Regulator
1/2"ODS
PS = 45 bar
Product use
These regulators are designed to maintain a constant evaporating pressure and thereby a constant surface temperature on the evaporator under varying evaporator loads. This regulator prevents too low evaporating pressure and therefore protects the water chiller from freezing or the formation of ice in air evaporators.
