Product Features
Low-Temperature Volumetric Efficiency

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.

Optimized Direct Suction Channel

Built with direct-path suction gas channels to lower internal pressure drop and minimize gas heating prior to compression, maximizing efficiency.

Wide Power Network Adaptability

Supports dual-frequency operation across 400V/50Hz and 460V/60Hz grids, ensuring seamless global integration for this semi hermetic reciprocating refrigeration compressor.

Integrated Field Maintenance Package
  • 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

Frequently Asked Questions
Q1: What are the thermal operating envelope limits for this semi hermetic reciprocating refrigeration compressor?

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.

Q2: What lubricant volume and level requirements apply to SP4LF1000 (SP4LF100E)?

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.

Q3: How does implementing a pump-down shutdown cycle benefit low-temperature system reliability?

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.

Q4: What vacuum evacuation level is required prior to initial refrigerant charging?

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.
