What Is a Semi-Hermetic Compressor?

Built for reliability and convenience, a semi-hermetic compressor houses both the motor and compressor in the same casing and is designed in a manner that provides easy access for maintenance. While open compressors rely on shaft seals to maintain internal pressure, hermetic and semi-hermetic compressors are able to prevent gas leaks since the key components are sealed within a steel shell. At Compressor Solutions Group, our meticulous remanufacturing process for semi-hermetic compressors is backed by decades of experience. Every spring, bolt, and bearing must meet the highest quality standards.

Benefits of
Semi-Hermetic Compressors



Semi-hermetic compressors are housed with a two-piece shell that allows easy access to the motor and compressor.

Less Leaks

Unlike open compressors, there is no shaft seal for gas to leak in a semi-hermetic compressor.


Since semi-hermetic compressors are designed to be easily accessed, this cuts down on overall costs and maintenance hours.
