The reciprocating semi hermetic compressor (SP4HF1200/SP4HF120E) is designed for medium-to-high temperature commercial refrigeration, liquid chillers, and HVAC systems. Built with a 4-cylinder layout, this model delivers 42 m³/h displacement at 50Hz (50.4 m³/h at 60Hz) with a 12 HP (8.9 kW) rated motor, offering smooth, energy-efficient performance under demanding duty cycles.
Optimized Suction Gas Circulation & Motor Cooling
Featuring an advanced gas passage design and optimized internal flow channels, this reciprocating semi hermetic compressor reduces pressure losses and gas turbulence. Cool suction gas flows past the motor windings prior to compression, providing uniform motor cooling and lowering overall energy consumption across various operating conditions.
Precision Machine Body & Integrated Compact Layout
The high-density cast iron housing operates under continuous working pressures up to 28 bar. Built with an integrated footprint, it houses the internal suction filter, shut-off valves, and safety mechanisms in a compact structure, reducing overall dimensions while simplifying installation and field maintenance.
Integrated Safety Valve System
To protect the compressor against extreme overpressure, an internal safety valve connects the high-pressure and low-pressure chambers. Engineered for rapid response and reliable resetting, it automatically discharges overpressure gas to maintain safe internal operating pressure without loss of refrigerant to the ambient environment.
Applications
Commercial Supermarket & Cold Storage Systems: Delivers stable cooling for supermarket display cases, walk-in coolers, and commercial cold storage rooms.
Commercial HVAC & Chillers: Ideal for packaged air conditioning units, modular liquid chillers, and environmental control systems.
Food Processing & Industrial Cooling: Provides consistent temperature management for commercial food processing lines and manufacturing cooling setups.
