Compact Housing & Integrated Gas Passages
The SP4HF1500 semi sealed compressor is designed with an optimized gas flow channel that minimizes pressure loss and improves overall volumetric efficiency. Its compact body structure integrates shut-off valves, oil strainers, and pressure sensors into a single frame, reducing physical footprint and simplifying installation in commercial systems.
High-Density Internal Suction Strainer
To prevent dirt and mechanical debris from reaching the motor and compression chamber, this 15HP semi sealed compressor features a built-in high-density suction strainer. Positioned conveniently on the outer side of the crankcase, it prevents dew condensation on the inlet housing while enabling quick inspection during service.
Multi-Voltage Motor with Efficient Gas Cooling
Equipped with specialized winding insulation, the internal motor supports Part-Winding (PW) starting and dual-frequency operation (50Hz / 60Hz). Cold suction gas passes directly around the motor windings before entering the cylinders, ensuring effective thermal control, low operating temperatures, and high stability across R22, R407C, R134a, and R404A applications.
Applications
Commercial HVAC Systems: Serves as a dependable semi sealed compressor for central water chillers and package air conditioning units.
Medium & High Temp Cold Storage: Provides stable cooling performance for agricultural storage and food distribution centers.
Industrial Process Cooling: Suitable for factory chillers requiring continuous operation under variable load conditions.
