Product Description
Refcomp SP4LN0800 SP4LN080E Low Temp Cold Storage Semi Sealed Compressor
Product Overview

Advanced semi-sealed compressor engineered for low-temperature cold storage applications with superior efficiency and reliability.

Key Features
  • Low-Temp Volumetric Performance: Delivering up to 50.4 m³/h displacement with 100% and 50% step capacity regulation, efficiently satisfying variable low-temperature refrigeration loads.
  • Direct Gas Flow Channel: Built with direct internal gas paths and high-strength casing rated up to 28 bar, minimizing suction pressure loss and maximizing compression efficiency.
  • Multi-Grid & Refrigerant Integration: Designed for dual-frequency 400V/50Hz and 460V/60Hz networks, operating smoothly with standard low-temp refrigerants including R22, R134a, R404A, R407C, and R507.
  • Integrated Service & Safety Kit: Factory-installed 230V/220W crankcase heater for off-cycle protection, INT69B2 motor thermal protection module, 360° rotatable suction (35mm) and exhaust (28mm) valves, internal suction gas filter, and high/low pressure safety relief valve.

Frequently Asked Questions
Q1: What lifting and handling precautions should be observed when transporting this semi sealed compressor?
A1: Always use the designated lifting eyelets on the body, maintain the unit in an upright orientation to prevent oil from entering suction passages, and protect connection ports against moisture during transit.
Q2: How can technicians identify liquid refrigerant floodback and what immediate measures should be taken?
A2: Liquid floodback typically causes rapid crankcase frosting, violent oil foaming in the sight glass, and abnormal casing noise; adjust thermal expansion valve superheat or perform a pump-down cycle immediately.
Q3: How should terminal box wiring be secured to maintain proper electrical enclosure protection?
A3: Use appropriately rated cable glands to seal entry points, tighten jumper connections to specified torque values, and verify solid ground continuity prior to energizing the motor.
Q4: What suction riser design rules ensure adequate oil return when operating this compressor at 50% partial capacity?
A4: Vertical suction lines should be sized properly or constructed with double-riser loops to keep gas velocity above 5 m/s during 50% step operation, preventing oil trapping in low-temperature evaporators.
