Piston compressors - semi-hermetic

A semi-hermetic piston compressor is a type of compressor commonly used in refrigeration and air conditioning systems.

Unlike hermetic compressors, which have a sealed casing, semi-hermetic compressors have a removable casing that allows for maintenance and repair of the compressor.

The compressor uses one or more pistons to compress refrigerant and move it through the system. The pistons are driven by an electric motor, which is located inside the compressor casing.

The casing also contains compressor valves, which control the flow of coolant through the system.

Semi-hermetic compressors are often used in large commercial and industrial refrigeration and air conditioning systems, where they are capable of handling high volumes of refrigerant and providing reliable, long-term operation. .

Semi-closed compressor structure: contains (piston, crankshaft, coils, oil pan, and electric motor)

Assembled into a single unit with openings and covers secured with screws and gaskets, allowing access for compressor maintenance when necessary.

Advantages of the semi-closed compressor

• Repairable in case of malfunction

• Suitable for higher outputs compared to closed compressors

• You can check the oil level.

• Discharge heads can be connected to control coolant regulation

Best-in-class performance

Copeland Disc Compressors have been the undisputed leaders in commercial refrigeration for over 30 years. Combining world-class efficiency and reliability, Disc is the compressor of choice to meet your refrigeration needs. The unique Disc compressor design provides improved efficiency in operating conditions where most semi-hermetic compressors operate. Rigorous life testing and 30 years of experience

The most reliable disc compressors in the industry

End users want cooling, and they want it reliably.

Even the most powerful compressors in the industry, such as Discus, can fail or malfunction under harsh conditions, such as poor installation. Faced with this challenge, Emerson engineers developed innovative technologies using compressor electronics to increase compressor reliability and service life.

All new disc compressors are shipped with built-in compressor electronics technology.

Using innovative and proprietary algorithms, the compressor acts as a sensor for protection and diagnosis of the compressor when adverse conditions exist. The compressor's electronic technology can proactively shut down the compressor to prevent future damage until the condition no longer exists, enabling longer compressor life and continued product integrity while protecting your investment in refrigeration.
