The semi hermetic refrigeration compressor (SP4HN1500/SP4HN150E) is built for high-capacity commercial liquid chilling, medium-to-high temperature cold storage, and heavy-duty HVAC applications. Featuring a 4-cylinder reciprocating design, it provides a displacement of 49 m³/h at 50Hz (58.8 m³/h at 60Hz) with a 15 HP (11.2 kW) rated motor, delivering efficient volumetric output and reliable continuous cooling under dynamic thermal loads.
360° Rotatable Shut-off Valves
Equipped with heavy-duty suction and discharge shut-off valves that feature a 360° rotatable flange design, this semi hermetic refrigeration compressor simplifies mechanical piping layout. Operating engineers can easily adjust valve orientation to align with system piping, reducing installation time and reducing physical stress on suction/discharge connections.
Integrated High-Density Suction Filter
Featuring a built-in high-density suction filter element, the unit removes scale, piping debris, and solid impurities before refrigerant enters the motor chamber. Positioned conveniently on the outer suction flange, the filter allows for quick inspection and routine cleaning without requiring full disassembly of the compressor body.
Advanced INT69B2 Motor Protection Module
To safeguard the motor against thermal overload, electrical imbalance, and high discharge temperatures, the compressor integrates an electronic INT69B2 protection module paired with embedded PTC thermistor sensors. The module continuously monitors internal coil temperatures, cutting control power instantly if safe limits are exceeded to prevent motor damage.
Applications
Commercial Supermarket & Cold Storage Systems - Provides stable, high-capacity refrigeration for medium-temperature food storage rooms, cold distribution centers, and display cabinets.
Liquid Chillers & Air Conditioning - Ideal for air-cooled and water-cooled liquid chiller plants supplying commercial building HVAC systems and industrial process cooling loops.
Industrial Process Fluid Cooling - Delivers consistent thermal control for commercial food manufacturing, beverage cooling, and industrial processing operations.
