Product Description
Refcomp SP4L2200 SP4L220E Semi Hermetic Type Reciprocating Compressor
Product Overview
High-performance semi-hermetic compressor designed for demanding low-temperature applications with reliable cooling output and advanced safety features.
- Low-Temperature High Displacement: Delivering a displacement of up to 103.3 m³/h with 100% and 50% step capacity regulation, this semi hermetic type compressor ensures reliable cooling output under heavy low-temperature loads.
- Direct Gas Path & Pressure Shell: Designed with direct-flow internal gas channels and a high-strength casing rated for 28 bar, reducing suction pressure losses and optimizing volumetric efficiency.
- Balanced Shafting & Safety Design: Built with a dynamically balanced 4-cylinder crankshaft, wear-resistant sleeve bearings, an internal safety relief valve, and an INT69B2 thermal protection module.
- Integrated Component Package: Features 360° rotatable suction (54 mm) and exhaust (28 mm) valves, a factory 230V / 150W crankcase heater, and an accessible internal suction filter for this semi hermetic type compressor.

Frequently Asked Questions
Q1: What procedure ensures proper oil level visibility during continuous low-temperature operation?
A1: Keep the standing oil level between 1/3 and 2/3 of the sight glass during operation, and verify that suction line gas velocity remains sufficient to return oil during 50% capacity step cycles.
Q2: What electrical protection settings apply when starting this semi hermetic type compressor?
A2: Circuit breakers and contactors must handle the 39 A maximum operating current while accommodating starting inrush currents of 102A (Part Winding) or 170A (Direct On Line).
Q3: How does the 360° rotatable valve feature simplify piping connection in commercial refrigeration units?
A3: The rotatable valve design allows installers to adjust line directions freely, avoiding pipe alignment stress and facilitating clean piping to the 54 mm suction and 28 mm exhaust lines.
Q4: What role does the 150W crankcase heater play before starting the system?
A4: The crankcase heater boils off liquid refrigerant dissolved in the lubricant during off-cycles, preventing oil foaming and lubrication breakdown upon compressor startup.
