Compressor Rack Units

A compressor rack unit is a fully integrated refrigeration solution that combines multiple compressors and essential components into a single factory-assembled system. By working in parallel, the compressors deliver precise capacity control, energy efficiency, and built-in redundancy for reliable operation in small to medium commercial applications across supermarkets, cold storage, food processing, and industrial applications.

Each rack is designed as a complete, plug-and-play package. The key components typically include:

Compressors– Semi-hermetic piston or screw compressors. Customers can choose the type and number of compressors (2–8+ units) depending on capacity and redundancy requirements.
Cut-off Valves– Installed on suction, discharge, and liquid lines for safe service and isolation.
Condenser– Available in air-cooled, water-cooled, or evaporative types (for condensing unit versions).
Oil Separator– High-efficiency separator with return system to keep compressors properly lubricated.
Three-in-One Device– Combines filter, sight glass, and dryer functions for reliable refrigerant management.
Liquid Receiver– Sized to system duty, with safety relief valves and service valves.
Heat Exchanger– Optional economizer or intercooler to boost efficiency.
Control Cabinet– PLC/HMI with compressor sequencing, capacity modulation, alarm history, and remote connectivity.
Pressure Controls– High/low pressure switches, oil pressure protection, and discharge temperature safeguards.
Expansion Valves & Accessories– For stable refrigerant flow and efficiency optimization.
