The guided rotor compressor (GRC) is a positive displacement rotary gas compressor

Gas compressor

A gas compressor is a mechanical device that increases the pressure of a gas by reducing its volume.Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe. As gases are compressible, the compressor also reduces the volume of a gas...

ally rotating rotor mounted on an eccentric drive shaft with a typical 80 to 85% adiabatic efficiency.

History

The development of the GRC started in 1990 to minimize the use of compressor valve plates and springs by using simple inlet/discharge ports.

Uses

The guided rotor compressor is under research as a hydrogen compressor

Hydrogen compressor

A hydrogen compressor is a device that increases the pressure of hydrogen by reducing its volume. Compression of hydrogen gas naturally increases its temperature, due to Charles' Law....

Hydrogen station

A hydrogen station is a storage or filling station for hydrogen, usually located along a road or hydrogen highway, or at home as part of the distributed generation resources concept. The stations are usually intended to power vehicles, but can also be used to power small devices. Vehicles use...
