Refcomp SP4H2500 SP4H250E AC Semi Hermetic Type Compressor

The SP4H2500 semi hermetic type compressor is standardly equipped with an INT69B2 electronic motor protection module (230V/1Ph/50-60Hz) connected to embedded PTC thermistors inside the motor windings. This solid-state module monitors winding temperatures in real time, automatically interrupting control circuits to prevent motor burnout during phase loss, electrical overloads, or thermal stress under continuous heavy-duty operations.

Featuring a cast body rated for working pressures up to 28 bar, this semi hermetic type compressor integrates direct internal suction gas channels that minimize flow resistance and pressure drop. The spatial layout houses internal components, suction strainers, and shut-off valves into a unified, compact frame that optimizes heat dissipation while keeping physical dimensions minimal.

Engineered for efficient system integration, this 4-cylinder semi hermetic type compressor incorporates built-in step capacity modulation for 100% and 50% operational output. The dual-step control system allows automatic load balancing, adjusting displacement to match partial refrigeration demands without frequent compressor cycling.
