CPCE hot gas bypass regulator adapt compressor capacity to actual evaporator load. |
||||
They are designed for installation in a bypass line between the low and high pressure sides of the refrigeration system, for hot gas injection between the evaporator and thermostatic expansion valve. |
||||
|
||||
• Direct connection to system suction line regulates hot gas injection independent of evaporator pressure drop : |
||||
• The regulator increases evaporator gas velocity, thus ensuring better oil return to compressor • Protection against too low an evaporating temperature, i.e. prevents evaporator icing |
||||
• May be used in the following EX range |
