Refcomp SP4HF1200 SP4HF120E Reciprocating Chiller Compressor for Rooftop AC Unit
Product Overview
The SP4HF1200 reciprocating chiller compressor is a 4-cylinder semi-hermetic unit engineered for high-temperature commercial refrigeration and HVAC liquid chilling applications.
Flexible Capacity Control (100% / 50%)
Equipped with a 2-stage capacity regulation mechanism (100% and 50%), this reciprocating chiller compressor enables precise output adjustment based on changing cooling demands. This step-control functionality reduces unnecessary energy consumption during partial-load operation in chiller systems.
Dynamic Balance Mechanics
Built with a custom-balanced crankshaft, durable connecting rods, and optimized pistons, the assembly delivers smooth rotational balance with reduced vibration and low operational noise. Pin bushings featuring high wear resistance support continuous duty and extend total service life.
Heavy-Duty Bearing System
The internal structure combines precision sliding bearings with integrated thrust washers to effectively absorb radial and axial mechanical loads. Supported by a continuous lubrication oil film, the bearing assembly is designed for long-term stability with a calculated lifespan of 60,000 to 80,000 hours.
High-Efficiency Motor & INT6982 Protection
Driven by a multi-voltage motor supporting part-winding start, the reciprocating chiller compressor incorporates a built-in INT6982 protection module to prevent motor overheating and electrical overload. The motor insulation and seal materials offer broad compatibility with R22, R134a, R407C, and R404A refrigerants.
Application Areas
  • Commercial Water Chillers: Suitable for centralized liquid chillers and HVAC air-conditioning systems operating under high-temperature conditions.
  • Industrial Process Cooling: Designed for industrial fluid chillers and process cooling systems requiring continuous, heavy-duty operation.
  • Commercial Cold Storage: Ideal for medium-to-high temperature food holding rooms, agricultural post-harvest storage, and distribution centers.
  • Supermarket Refrigeration Racks: Applicable to multi-compressor parallel rack systems feeding commercial display cases and walk-in coolers.

Frequently Asked Questions
  • How do I confirm if the SP4HF1200 model matches my chiller load requirements?
    You can evaluate model suitability by comparing your system's required cooling load, operating temperature range, and refrigerant type against the compressor's displacement rate (42.0 m³/h at 50Hz / 50.4 m³/h at 60Hz). Providing these system parameters allows technical teams to verify precise capacity alignment.
  • What factors should be considered when integrating this unit into a multi-compressor rack?
    When installing in a parallel rack configuration, ensure adequate oil level balancing, correct suction manifold sizing, and appropriate control logic settings to support smooth 50% and 100% capacity step switching.
  • What pre-commissioning checks should be conducted regarding compressor lubrication?
    Before initial startup, verify that the crankcase heater (230V/220W) has been energized for the recommended pre-heating period, check that the oil charge (2.6 dm³) is properly visible in the sight glass, and confirm suction filter cleanliness.
  • What warranty coverage does Coolstart provide for semi-hermetic compressors?
    Coolstart provides a standard 1-year warranty across all compressor product lines, covering manufacturing defects under standard operating conditions.
  • What are the typical lead times and export packaging arrangements?
    Sample units in stock ship within 3 business days, while standard production orders are delivered in 10 to 15 working days. All export compressors are secured in wooden cases for sea or air freight.
