These compressors are often described as being either hermetic, open, or semi-hermetic, to describe how the compressor is enclosed and how the motor drive is situated in relation to the gas or vapor being compressed. Some compressors outside of refrigeration service may also be hermetically sealed to some extent, typically when handling toxic ...
Hermetic seal. A hermetic seal is any type of sealing that makes a given object airtight (preventing the passage of air, oxygen, or other gases). The term originally applied to airtight glass containers, but as technology advanced it applied to a larger category of materials, including rubber and plastics.
Compressors are often described as being either open, hermetic, or semi-hermetic, to describe how the compressor and/or motor is situated in relation to the refrigerant being compressed. Variations of motor/compressor types can lead to the following configurations: Hermetic motor, hermetic compressor; Hermetic motor, semi-hermetic compressor
Inverter compressor. In air conditioning, an inverter compressor is a compressor that is operated with an inverter. In the hermetic type, it can either be a scroll or reciprocating compressor. This type of compressor uses a drive to control the compressor motor speed to modulate cooling capacity. Capacity modulation is a way to match cooling ...
A reciprocating compressor or piston compressor is a positive-displacement compressor that uses pistons driven by a crankshaft to deliver gases at high pressure. [1][2] Pressures of up to 5,000 psig are commonly produced by multistage reciprocating compressors. The intake gas enters the suction manifold, then flows into the compression cylinder ...
Chiller. A chiller is a machine that removes heat from a liquid coolant via a vapor-compression, adsorption refrigeration, or absorption refrigeration cycles. This liquid can then be circulated through a heat exchanger to cool equipment, or another process stream (such as air or process water). As a necessary by-product, refrigeration creates ...

Compression Systems began in 1833 when Charles and Elias Cooper established a foundry in Mt. Vernon, Ohio. "Cooper", as it was known, was licensed to produce the Corliss steam engine in 1869 and entered the production of natural gas internal combustion engines in 1900. In 1929, Cooper merged with Bessemer Gas Engine Company, which was founded ...
