Product Description
Refcomp SP4LN1000 SP4LN100E Low Temp Cold Storage Semi Sealed Compressor
Product Overview
This semi-hermetic reciprocating compressor delivers high-displacement output for low-temperature applications with efficient capacity regulation and robust construction.
  • Low-Temperature High-Displacement Output: Delivering a displacement of 58.8 m³/h at 60Hz with 100% and 50% capacity step regulation, efficiently managing fluctuating thermal loads in freezer environments.
  • Direct Suction & Pressure Housing: Features direct-path internal gas channels within a 28 bar rated housing, minimizing suction pressure loss and maximizing overall compression efficiency.
  • Multi-Refrigerant System Integration: Supports operation across 400V/50Hz and 460V/60Hz grids with standard low-temperature refrigerants, ideal for diverse commercial refrigeration systems.
  • Factory Protection & Maintenance Hardware: Includes factory-installed protection systems and adjustable components for reliable operation.

Frequently Asked Questions
Q: How should hot gas defrost cycles be managed to protect this semi hermetic reciprocating compressor?
A: Ensure a suction liquid accumulator is fitted to catch unevaporated liquid returned during defrost termination, and delay full capacity loading until system pressures normalize.
Q: What expansion valve setting precautions prevent oil dilution in low-temperature evaporators?
A: Maintain stable superheat (at least 5-8 K at the compressor suction inlet) to prevent wet compression and keep refrigerant from dissolving excessive lubricant in the crankcase.
Q: What maximum pressure limits apply during system pressure testing and leak checking?
A: Perform pressure testing using dry nitrogen, ensuring test pressures do not exceed the compressor low-side or high-side design limits (housing pressure limit is 28 bar).
Q: How often should compressor oil be replaced during continuous commercial operation?
A: Change the initial oil charge after the first 100 hours of run-in, and subsequently conduct oil analysis or replacement every 10,000 operational hours or once a year.
