06CC665 Semi Sealed Compressor

The 06CC665 is a heavy-duty 20 HP semi sealed compressor engineered specifically for demanding low-temperature commercial and industrial refrigeration environments. Featuring a 6-cylinder architecture divided into 4 low-pressure stage cylinders and 2 high-pressure stage cylinders, this advanced unit achieves powerful two-stage compression inside a single body. With an impressive low-stage displacement of 61.2 m³/h and a high-stage displacement of 30.6 m³/h at 1450 RPM, it provides exceptional thermal performance for deep-freezing warehouses, blast tunnels, and supermarket rack systems operating between -30°C and -50°C.

Operating single-stage compressors at extreme pressure ratios often results in high discharge temperatures and degraded lubrication efficiency. The 06CC665 semi sealed compressor mitigates these mechanical stresses by dividing the compression workload across two internal stages. Equipped with an integrated plate heat exchanger subcooler, the system subcools liquid refrigerant before it reaches the expansion valve. This design drastically increases overall system efficiency, enables smaller liquid line piping, and lowers total refrigerant charge requirements.

Built with a rugged cast iron frame weighing 243 kg and supported by an expanded 9.0 L crankcase oil capacity, this heavy-duty semi sealed compressor ensures long-term operational stability under heavy continuous loads. Serving as a direct functional replacement for the 06CY665 model, it comes standard with 42 mm (1-5/8 in) suction and 35 mm (1-3/8 in) discharge ports. It offers broad chemical compatibility across eco-friendly refrigerant setups including R404A, R507, and R22.
