Refcomp SP4LF1000 SP4LF100E Semi-Hermetic Reciprocating Chiller Compressor
Product Overview
The SP4LF1000 reciprocating chiller compressor delivers reliable performance for demanding commercial and industrial cooling applications with advanced energy regulation and robust construction.
Key Features
  • Flexible Energy Regulation & Load Adaptation: Solenoid-driven 2-step capacity control system (100% and 50% steps) minimizes motor cycling, maintains steady suction pressure, and optimizes electrical efficiency during partial-load conditions.
  • Suction Gas-Cooled Motor Architecture: Internal flow channels pass cool returning suction gas across motor windings, maintaining low operational temperatures. Supports dual-frequency power supplies (400V/50Hz and 460V/60Hz PW) and multiple refrigerants including R22, R407C, R134a, R404A, and R507.
  • Robust 4-Cylinder Drive Assembly: Heavy-duty 4-cylinder platform with dynamically balanced crankshaft, wear-resistant journal bearings, and precision-machined connecting rods reduces radial wear, dampens gas pulsation, and lowers operating vibration.
  • Integrated Filtration & Safety Safeguards: High-density suction filter screen traps debris before reaching compression chamber. Internal pressure relief valve and INT6902 electronic motor protection module guard against overpressure, thermal overload, and phase faults.
Applications
  • Commercial Liquid & Water Chillers: Modular central chillers and commercial air conditioning loops requiring step capacity control
  • Industrial Process Chilling: Plastic injection cooling, chemical processing, and pharmaceutical temperature maintenance
  • Low-Temperature Cold Storage: Walk-in freezers, cold chain distribution hubs, and food storage facilities
  • Parallel Multi-Compressor Racks: Supermarket refrigeration racks with varying daily load profiles

Frequently Asked Questions
Q1: How does the SP4LF1000 handle part-load operations in chiller applications?
A1: The 100% and 50% energy regulation system adjusts displacement to match reduced cooling demand, avoiding motor restart spikes and maintaining precise chiller outlet liquid temperatures.
Q2: What suction and discharge line dimensions are required during system piping layout?
A2: The unit is equipped with a 35 mm (1-3/8") suction connection and a 28 mm (1-1/8") discharge connection, with rotatable stop valves to simplify line positioning in compact chiller skids.
Q3: What operational safeguards are recommended for low-evaporating temperature conditions?
A3: Ensure the 230V/220W crankcase heater is energized during standbys to prevent oil dilution, and verify suction superheat to avoid liquid slugging during rapid load changes.
Q4: Can Coolstart customize nameplates and product branding for OEM chiller manufacturers?
A4: Yes, we provide full OEM customization including multi-language nameplates, custom logo placement, and modified technical labeling for volume production orders.
Q5: What are the available payment terms and sample lead times?
A5: Sample orders are dispatched within 3 business days, with payment supported via T/T and Western Union. Standard production orders are completed within 10 to 15 working days.
