06CC228 7.5HP Two Stage Refrigeration Semi Hermetic Compressor

Designed for heavy-duty commercial cold storage and deep-freezing applications, this 7.5HP carrier semi hermetic compressor utilizes an advanced two-stage compression mechanism built within a single compact body. Featuring 6 cylinders—4 cylinders for low-pressure compression and 2 cylinders for high-pressure compression—it delivers a low-stage displacement of 31.7 m³/h and high-stage displacement of 15.9 m³/h at 1450 rpm. An integrated plate heat exchanger subcooler maximizes liquid subcooling, allowing systems to operate with reduced refrigerant charge while maintaining exceptional thermal capacity under severe freezing conditions.

By dividing total compression work into two distinct stages in one body, this carrier semi hermetic compressor operates at significantly lower compression ratios per cylinder. This optimized internal pressure balance reduces mechanical stress, lowers discharge temperatures, and eliminates the need for separate booster compressors or external subcooler modules. The result is a highly durable refrigeration core that prevents oil breakdown and ensures continuous, low-temperature operation.

Built to comply with global environmental standards, this high-efficiency carrier semi hermetic compressor is UL-approved and fully compatible with R22, R404A, and R507 refrigerants. Supported by a robust 154 kg cast-iron housing, high-flow Swedish steel valve plates, and a 4.5 L oil charge capacity, it delivers optimal bearing lubrication and long-term operating resilience in industrial refrigeration systems.
