Evaporator Pressure Regulator Diagram. How to test EPR (evaporator pressure regulator) Automotive Air In commercial refrigeration, these valves are most commonly referred to as evaporator pressure regulator (EPR) valves and. the back pressure is quite high (around 60 psig r404a)(the pressure goes way down if i turn on only one evap.(8psig) or two (30psig.

There are a couple of reasons why you may want to control the suction pressure in an evaporator Evaporator Pressure Regulators Sporlan Evaporator Pressure Regulating valves (EPRs) are designed to provide an economical means of accurately maintaining evaporator pressure and temperature under varying evaporator loads

Pressure at the outlet is exerted on the underside of the bellows and on top of the seat disc. This valve is fitted in the suction line to control the pressure in the evaporator, to prevent it dropping below a predetermined pressure Sporlan Evaporator Pressure Regulating valves (EPRs) are designed to provide an economical means of accurately maintaining evaporator pressure and temperature under varying evaporator loads
PPT SECTION 5 COMMERCIAL REFRIGERATION UNIT 25 SPECIAL REFRIGERATION. the back pressure is quite high (around 60 psig r404a)(the pressure goes way down if i turn on only one evap.(8psig) or two (30psig. The primary function of an EPR is to prevent the evaporator pressure from falling below a predetermined value or setting.
Water Pressure Regulators What They Are and How They Work. The evaporator pressure regulator, type KVP opens on a rise in pressure on the inlet side, i.e when the pressure in the evaporator exceeds the set value
