Refcomp SP4LF1000 SP4LF100E Semi Hermetic Reciprocating Refrigeration Compressor
Featuring a displacement of up to 58.8 m³/h at 60Hz, this semi hermetic reciprocating refrigeration compressor maintains steady mass flow and high performance in deep-freeze applications.
Built with direct-path suction gas channels to lower internal pressure drop and minimize gas heating prior to compression, maximizing efficiency.
Supports dual-frequency operation across 400V/50Hz and 460V/60Hz grids, ensuring seamless global integration for this semi hermetic reciprocating refrigeration compressor.
- Dual 100% and 50% step capacity regulation
- 360° adjustable suction (35 mm) and discharge (28 mm) valves
- Factory 230V / 220W crankcase heater
- Built-in INT69B2 motor thermal protection module

A1: Discharge gas temperature must not exceed 120°C, and suction superheat should be maintained between 5K and 10K to avoid thermal degradation during extreme low-evaporating cycles.
A2: The unit requires a 2.6 dm³ oil charge, with the standing oil level maintained between 1/3 and 2/3 of the oil sight glass during active operation.
A3: A pump-down cycle evacuates suction line refrigerant prior to compressor stop, preventing refrigerant migration into the oil sump and eliminating liquid knock on subsequent startups.
A4: Evacuate both high and low sides of the system down to at least 0.5 mbar (500 microns) to ensure non-condensable gases and moisture are completely removed.
