4D*JN3000

The Copeland 4D*JN3000 is a 4-cylinder semi-hermetic reciprocating compressor built on Copeland's proven D-series platform, designed for commercial refrigeration and air conditioning applications running on R-22.

With a nominal rating of 30 HP, the 4DJN-3000 delivers reliable capacity across medium-temperature refrigeration duty cycles. The semi-hermetic design seals the motor and compression mechanism in a common housing, combining the serviceability of an open compressor with the leak-free integrity of a hermetic unit. This makes it a practical choice for supermarket display cases, walk-in coolers, food service equipment, and light commercial HVAC systems.
