Refcomp SP4HF1000 SP4HF100E Semi Hermetic Compressor for Cold Storage
Product Overview
The semi hermetic compressor (SP4HF1000/SP4HF100E) is built for medium-to-high temperature commercial refrigeration, process chilling, and commercial HVAC systems. Delivering a displacement of 35 m³/h at 50Hz (42 m³/h at 60Hz) with a 10 HP (7.5 kW) rated motor, this 4-cylinder unit ensures low vibration, quiet running, and reliable continuous cooling.
Key Features
Precision Crankshaft, Connecting Rod & Piston Dynamics
Featuring custom-designed balanced crankshafts with counterweights, this semi hermetic compressor maintains rotational balance and low mechanical vibration. Advanced valve plate design minimizes gas flow friction losses, while optimized piston geometry paired with wear-resistant connecting rod bushings ensures extended durability in demanding cooling cycles.
Hydrodynamic Sliding Bearings for Extended Service Life
Engineered with babbitt-lined hydrodynamic sliding bearings and thrust washers, the internal mechanical structure prevents axial and radial friction. This high-precision layout operates with minimum wear and low noise, delivering a design service life of 50,000 to 80,000 operating hours.
Advanced INT69 Protection Module & Electrical Safety
To protect the motor against thermal overload and phase faults, the unit comes equipped with an electronic INT69 protection module and embedded PTC thermistors. The protection system monitors coil temperatures in real time, preventing motor burnout and ensuring long-term operational safety across various grid power supplies.
Applications
Commercial Supermarket & Cold Room Systems: Provides stable medium-to-high temperature refrigeration for food display cases, cold rooms, and commercial storage hubs.
Commercial HVAC & Air Conditioning: Ideal for packaged air conditioning units, modular chillers, and building environmental control systems.
Industrial Process Chilling: Delivers precise fluid and thermal cooling control for commercial food processing and manufacturing facilities.
