Product Details

KVL 12 KVL 15 Danfoss Type CPR Crankcase Pressure Regulator Regulating Valve

 

A crankcase pressure regulator (CPR) is a common accessory added to many low-temperature refrigeration applications, such as walk-in and reach-in freezers. They are designed to prevent the compressor's motor from overloading when its crankcase pressure rises above its designed working pressure. On many low-temperature applications, this can occur during or after a defrost cycle, or after a normal shutdown period. The CPR is an outlet pressure regulator and will not allow the crankcase pressure to rise above a predetermined level.
