The ZR36K3-PFJ-522 is a hermetic scroll refrigeration compressor in the Copeland ZR series — commonly used in HVAC and refrigeration systems (air conditioners, cold rooms, etc.). Scroll compressors are reliable and efficient designs replacing older piston types in many applications.
Typical Specifications

Horsepower: ~3 HP
Voltage: 220–240 V single phase (1Φ) at 50 Hz – common in many residential/light commercial systems
Refrigerant: R-22 (most listings show R22; some variants can also be rated R407C/R134a)
Rated Load Amps (RLA): ~16.4 A
Locked Rotor Amps (LRA): ~82 A

Application: Medium-temperature HVAC / refrigeration systems (air conditioners, chillers, cold rooms)
Use & Compatibility Notes
~ These compressors are hermetic (sealed) — the motor and compression parts are inside a welded steel shell, so they are typically replaced as a unit.
~ Because many listings show R-22 versions, confirm the refrigerant type before installing, especially since R-22 is being phased out in many regions.
~Check that electrical supply (220–240 V, single phase) matches local system specs.
