Refcomp SP4HF1500 SP4HF150E R22 Semi Sealed Compressor for Condensing Unit
Product Description
The semi sealed compressor (SP4HF1500/SP4HF150E) is built for medium-to-high temperature commercial refrigeration, liquid chillers, and industrial HVAC applications. Operating with a 4-cylinder reciprocating design, it delivers a displacement of 49 m³/h at 50Hz (58.8 m³/h at 60Hz) powered by a 15 HP (11.2 kW) motor, delivering reliable energy efficiency under continuous operating loads.
Key Features
- Flexible Step Capacity Modulation: 2-stage capacity regulation (50% and 100%) adapts to dynamic thermal load changes and optimizes power consumption during part-load cycles.
- 360° Rotatable Shut-off Valves: High-flow suction and discharge shut-off valves with 360° rotational adjustment for flexible mechanical room layouts and simplified pipe routing.
- Integrated High-Density Suction Filter: Internal filter element captures debris and particulate matter before refrigerant reaches the motor winding chamber, allowing quick inspection and easy cleaning.
Applications
- Commercial Supermarket & Cold Storage: Stable cooling for walk-in coolers, medium-temperature display cabinets, and regional food storage rooms.
- Commercial Chillers & HVAC: Ideal for air-cooled and water-cooled liquid chillers, packaged HVAC units, and industrial environmental control systems.
- Industrial Process Cooling: Constant displacement cooling for commercial food manufacturing, beverage cooling, and process fluid lines.
