Product Description
Refcomp SP6H3700 SP6H370E Semi-Hermetic Compressor for Chiller
Product Overview
  • Three-Stage Capacity Control - Offers 100%, 66%, and 33% energy regulation stages, allowing this reciprocating chiller compressor to match fluctuating system thermal loads and reduce part-load energy consumption.
  • Six-Cylinder Direct Flow Geometry - Features an optimized 6-cylinder valve plate layout and direct-path gas suction channels to minimize internal pressure losses and optimize volumetric efficiency.
  • Heavy-Duty Mechanical Protection - Built with a dynamically balanced crankshaft, wear-resistant sleeve bearings, an internal safety relief valve, and an INT69B2 module for continuous motor thermal protection.
  • Standard Component Package - Includes 360° rotatable suction (54 mm) and discharge (35 mm) valves, 230V / 150W crankcase heater, and high-density internal suction gas filter.

Frequently Asked Questions
What operating environment factors should be verified prior to placing this reciprocating chiller compressor into service?
Ensure adequate ambient room ventilation, keep ambient temperatures within allowable limits, and protect electrical connections against excessive moisture, dust, or corrosive vapors.
How does capacity stepping improve running efficiency during partial load conditions?
Modulating output down to 66% or 33% prevents frequent compressor cycling under reduced cooling demand, stabilizing leaving water temperatures while lowering power usage.
What diagnostic steps are recommended if the compressor trips on motor protection?
Inspect the INT69B2 control module wiring, verify line voltage balance across all power phases, check running current against the 60 A maximum, and confirm sufficient suction gas cooling.
What mounting and piping considerations help manage vibration when integrating a reciprocating chiller compressor?
Install flexible vibration absorbers on suction and discharge lines, secure the unit with resilient rubber mounting pads, and ensure rigid alignment of connected refrigeration piping.
