Product Description
Refcomp SP4LN0600 SP4LN060E SP Series Reciprocating Semi Hermetic Compressor
Product Overview
Optimized for deep-freeze cooling applications, this reciprocating semi-hermetic compressor delivers reliable performance with advanced capacity control and robust construction.
- Optimized Low-Temp Compression: Designed for deep-freeze cooling with displacement up to 42 m³/h and 100%/50% capacity step control for efficient refrigeration load management.
- Direct-Path Suction Flow: Features direct internal gas channels and high-strength housing rated for 28 bar, minimizing pressure drop and maintaining high volumetric efficiency.
- Heavy-Duty Internal Drive Mechanism: Built with dynamically balanced 4-cylinder crankshaft, wear-resistant sleeve bearings, and internal safety relief valve for low-temperature operation.
- Standard Protection & Service Package: Includes INT69B2 motor thermal overload protection, factory-installed 230V/220W crankcase heater, and 360° rotatable suction (28mm) and exhaust (22mm) shut-off valves.

Frequently Asked Questions
Q1: What oil balance precautions should be taken when installing this compressor in a parallel rack system?
A1: Install common oil-equalizing lines and electronic oil level regulators across all rack units to maintain uniform crankcase oil levels during staged compressor cycling.
Q2: What potential causes should be checked if discharge temperature rises excessively during low-evaporating operation?
A2: Inspect for excessive suction superheat, insufficient mass flow, degraded lubricant, or restricted airflow across any optional cylinder head cooling fan.
Q3: What technical details are needed when ordering customized low-temperature refrigeration skids using this model?
A3: Provide target evaporating/condensing temperatures, total cooling load requirements, defrost method, voltage supply, and local ambient room conditions.
Q4: How do low ambient room temperatures affect off-cycle crankcase heater control?
A4: Keep the 220W crankcase heater energized during all standby periods to maintain oil temperature above ambient levels and prevent liquid refrigerant migration.
