Product Structure
- The refrigeration system (rack) comprises a compressor, oil separator, oil cooler, control valves and fittings, refrigerant reservoir, condenser, electronic control devices, and PLC control.
- Internationally renowned compressor and fittings brands include MYCOM, BITZER, KOBELCO, FUSHENG, Danfoss, and Parker.
- Structural steel base platform with high-efficiency semi-hermetic and open screw compressors.
- The rack controller acts as the system’s core, managing compressors, condensers, defrost cycles, and other components for stability. It also monitors temperatures to uphold product integrity, requiring no operator intervention during operation.
Advantage
- Integral electric defrost control system.
- Mechanical and electronic controls for oil, defrost cycles, and liquid levels.
- Horizontal and vertical receivers with liquid level indicators and pressure relief valves. Insulated suction lines ensure efficiency.
- Leak-tight construction features preformed tubing, minimal brazed joints, and flare fittings, with units leak-tested at the factory.
- Pressure vessels can be ASME or PED certified upon request.
- The PLC touch-screen controller serves as the system’s central control, managing compressors, condensers, defrost cycles, and other rack components to maintain system stability while monitoring temperatures for product integrity.
