Product Description
Refcomp SP4L2500 SP4L250E Semi Hermetically Sealed Reciprocating Compressor
Product Overview
High-Displacement Low-Temp Output

Delivering an exhaust volume of up to 123.5 m³/h with 100% and 50% step energy regulation, this semi hermetically sealed compressor meets demanding low-temperature refrigeration duties.

Direct Gas Flow Geometry

Featuring an optimized 4-cylinder design with direct suction gas passages inside a 28 bar pressure-rated casing, reducing internal pressure drops and maintaining high compression efficiency.

Broad Dual-Frequency Grid Adaptability

Engineered to operate seamlessly across 400V/50Hz and 460V/60Hz industrial power supplies, this semi-hermetic compressor supports multi-refrigerant low-temperature systems.

Standard Protection & Serviceability Kit
  • 360° adjustable suction (54 mm) and exhaust (35 mm) shut-off valves
  • Factory-installed 230V / 150W crankcase heater for off-cycle oil protection
  • Built-in INT69B2 electronic module for thermal motor overload protection

Frequently Asked Questions
Q1: What electrical insulation testing guidelines should be followed during routine maintenance of this semi hermetically sealed compressor?
Use a 500V megohmmeter to measure motor winding-to-ground insulation resistance, ensuring values remain well above 5 MΩ prior to re-energizing the compressor after extended shutdowns.
Q2: How does the 25 Hp motor handle part-winding starting sequences in large system installations?
Part-winding starting energizes the first set of motor windings to reduce initial inrush current to 123 A before connecting full windings, mitigating power grid voltage dips during startup.
Q3: What structural vibration isolation measures are recommended when mounting this 220 kg unit on a steel rack?
Install factory-specified rubber dampening pads under all mounting feet and use flexible corrugated pipe joints on suction and discharge lines to isolate mechanical resonance.
Q4: What specific temperature sensor placement yields accurate discharge monitoring for deep-freeze operation?
Position the discharge temperature probe directly on the discharge line within 100 mm of the shut-off valve port to ensure fast thermal feedback and prevent oil carbonization.
