The SP4HF1200(SP4HF120E) reciprocating semi hermetic compressor features dual-stage capacity regulation at 100% and 50%, allowing system operators to seamlessly match output with changing thermal loads while cutting overall power demand during partial-load conditions.
Heavy-Duty Mechanical Design & Bearings
Engineered with floating dynamic sleeve bearings and a precise counterweighted crankshaft layout, this 4-cylinder reciprocating semi hermetic compressor minimizes operational vibration, suppresses friction losses, and extends total service life in demanding high-temperature duties.
Integrated System & Motor Protection
Equipped with an advanced INT6982 motor protection module, an internal high-density suction strainer, and an internal safety valve rated for high-pressure limits, the unit effectively guards against electrical overloads, debris contamination, and unexpected pressure spikes.
Applications
Commercial HVAC Systems: Ideal for high-capacity liquid chillers and commercial air conditioning units requiring precise load adjustment.
Cold Storage Facilities: Provides consistent high-temperature and medium-temperature cooling performance for food preservation and distribution centers.
Industrial Process Cooling: Well-suited for factory process chillers that demand high operational reliability under varying thermal loads.
Supermarket Refrigeration: Serves as a dependable reciprocating semi hermetic compressor choice for centralized rack systems managing multiple display cases.
