Refcomp SP4HN1500 SP4HN150E 460V R22 Semi Hermetic Cold Room Compressor
The SP4HN1500 cold room compressor is a 4-cylinder semi-hermetic reciprocating unit designed for reliable performance in commercial cold storage and industrial chilling applications.
Flexible Capacity Regulation (100% / 50%)
Equipped with step energy regulation capabilities, this cold room compressor allows operators to toggle between 100% and 50% displacement output. This flexible load matching optimizes energy consumption during partial cooling demand and fluctuating thermal loads in refrigerated facilities.
Durable Bearing System Construction
Built with high-precision sliding bearings and integrated thrust washers, the bearing mechanism absorbs significant radial and axial forces. Supported by a continuous lubrication film, it delivers outstanding operational stability and extended operational lifespan.
360° Rotatable Shut-Off Valves
The suction and discharge shut-off valve assembly can be rotated 360 degrees to align effortlessly with existing piping layouts. This rotatable design simplifies field positioning, minimizes pipe stress, and reduces installation overhead for equipment builders.
Low-Loss Housing & Streamlined Gas Path
Featuring an optimized gas channel layout, this cold room compressor reduces internal suction pressure drop and flow turbulence. The compact housing integrates the suction strainer and service valves into a space-saving structure suitable for tight rack frames.

Frequently Asked Questions
How do I select the proper model for my cold room system?
Evaluate required cooling capacity, target evaporating and condensing temperatures, and refrigerant type against the compressor displacement rate. Providing exact working conditions allows engineering teams to confirm exact model sizing.
What precautions should be taken when retrofitting this compressor into existing refrigeration equipment?
Confirm line connection diameters, inspect mounting pad leveling, verify refrigerant compatibility, and check electrical panel capacity against motor starting current requirements.
How does step energy regulation benefit cold storage room operations?
Step regulation adjusts compressor output to match changing thermal loads, reducing unnecessary motor cycling and lowering overall power consumption during low-load periods.
What warranty coverage does Coolstart provide for semi-hermetic compressors?
Coolstart provides a standard one-year warranty across all compressor product lines, covering manufacturing and material defects under standard operating conditions.
