Refcomp SP4L2200 SP4L220E R404A Semi-Hermetic Compressor for Cold Storage
Product Description
Solenoid-Driven Capacity Regulation (100% / 50%)
Engineered with a solenoid-actuated energy regulation system, this semi-hermetic compressor provides 100% and 50% capacity steps to match dynamic cooling demands. By modulating displacement during part-load operating periods, the unit stabilizes suction pressure, avoids frequent motor cycling, and reduces power consumption in commercial freezing applications.
Advanced Floating Sleeve Bearing System
Incorporating high-precision floating sleeve bearings paired with durable thrust washers, this semi-hermetic compressor eliminates localized shaft friction and minimizes radial wear. The optimized lubrication geometry ensures low-noise operation and extends mechanical design life up to 50000-80000 running hours.
Heavy-Duty 4-Cylinder Reciprocating Assembly
Built around a high-rigidity casing rated for working pressures up to 28 bar, the compressor features a dynamically balanced crankshaft with integrated counterweights and bronze wrist pin bushings. This robust mechanical structure absorbs operational shock, dampens gas pressure pulsations, and delivers smooth running characteristics during continuous low-temperature operation.
Integrated Motor Protection & Pressure Relief
To safeguard internal electrical and mechanical components, the semi-hermetic compressor is equipped with an INT6902 electronic motor protection module that guards against phase loss and thermal overload. An internal differential safety valve automatically equalizes high-to-low pressure during sudden system anomalies, while an outer-accessible suction filter screen traps system contaminants.
Application
Large-Scale Walk-In Freezers & Cold Stores
Ideal for supermarket cold rooms, commercial freezing facilities, and central cold storage warehouses.
Blast Freezing & Fast Chilling Tunnels
Suitable for rapid chilling and flash-freezing production lines requiring high volumetric displacement.
Cold Chain Logistics Distribution Hubs
Designed for refrigerated logistics centers requiring continuous, low-vibration operation.
Industrial Process Temperature Maintenance
Well-suited for pharmaceutical storage, chemical processing, and industrial liquid cooling systems.

FAQ
Q1: What are the main benefits of the 54 mm (2-1/8") suction line connection on the SP4L2200?
A1: The larger 54 mm suction diameter reduces gas flow velocity and pressure drop, maximizing volumetric efficiency under low-evaporating-temperature conditions.
Q2: How does the Part-Winding (PW) motor configuration assist in starting heavy electrical loads?
A2: Part-Winding starting steps down the peak electrical inrush current from 170 A (DOL) to 102 A (PW), minimizing line voltage drop across regional power networks.
Q3: What maintenance procedure should be followed for the outer-accessible suction filter?
A3: Service engineers can isolate the compressor, depressurize the casing, and unbolt the side end plate to extract and clean the filter mesh without removing system piping.
Q4: Can Coolstart provide customized nameplates and private branding for OEM machine builders?
A4: Yes, we provide full OEM/ODM branding services, including multi-language nameplates, custom logo placement, and modified parameter labeling for qualified volume orders.
Q5: What standard lead times apply for sample and batch factory shipments?
A5: In-stock sample units can be dispatched within 3 business days, while standard batch production orders are completed within 10 to 15 working days.
