KVR 22 Danfoss Type Condensing Pressure Regulator 7/8'' 034L0094
Condensing pressure regulator is used to prevent the condensing temperature in a refrigeration system from dropping too low in a refrigeration system, especially during cold weather. They can be fitted in the hot-gas line downstream of the T-fitting branch to the receiver pressure regulator or in the condensate line.
