Designed for efficient low-temperature refrigeration performance, this Refcomp semi-hermetic compressor features a solenoid-driven capacity control system supporting 100% and 50% output steps. Matching compressor displacement directly with reduced evaporator loads prevents excessive motor cycling, stabilizes suction pressure, and optimizes electrical efficiency during part-load holding periods.
Featuring an internal gas-flow path, returning suction gas passes directly across the motor housing to keep operating temperatures low under low-evaporating-temperature conditions. This Refcomp semi-hermetic compressor motor supports dual-frequency power supplies (400V/50Hz and 460V/60Hz PW) and is fully compatible with multiple refrigerants, including R22, R407C, R134a, R404A, and R507.
Built on a heavy-duty 4-cylinder platform, this Refcomp semi-hermetic compressor incorporates a dynamically balanced crankshaft with wear-resistant journal bearings and precision piston-connecting rod assemblies. The optimized mechanical geometry dampens gas pulsation and minimizes radial vibration during continuous duty.
To ensure operational safety under demanding conditions, the Refcomp semi-hermetic compressor is equipped with an INT6902 electronic protection module that guards against motor overheating and phase imbalance. An internal high-to-low pressure safety valve automatically relieves internal casing overpressure, while an outer-accessible suction filter screen prevents system debris from entering the cylinders.

Q1: What technical parameters must be verified when replacing an existing unit with the SP4LF0800?
A1: Key checks include matching the mounting footprint dimensions, suction and discharge pipe diameters (35 mm and 28 mm), electrical voltage/frequency, and ensuring oil type compatibility with your current refrigerant.
Q2: What should operators check if the INT6902 motor protection module trips during operation?
A2: Operators should inspect for motor winding thermal overload, check control circuit supply voltage, verify operating suction superheat, and measure discharge gas temperature before attempting a system reset.
Q3: Why must the crankcase heater be energized prior to compressor startup in cold environments?
A3: Preheating the crankcase drives off dissolved refrigerant from the lubricating oil during idle periods, preventing oil foaming and ensuring immediate bearing lubrication upon startup.
Q4: Can Coolstart provide custom nameplates and private labeling for OEM system builders?
A4: Yes, we offer full OEM/ODM support including multi-language nameplate customization, custom branding, and technical parameter labeling for qualified production orders.
Q5: What standard warranty policy applies to Coolstart semi-hermetic compressors?
A5: All Coolstart compressors are backed by a standard 1-year factory warranty covering manufacturing and material defects under rated operating conditions.
Whether you are designing new parallel compressor racks or replacing units in existing cold chain facilities, Coolstart provides factory-direct technical guidance and reliable compressor solutions.
