Centrifugal Compressor is a machine in which a particular gas or vapor is compressed by a radial acceleration by an impeller with the help of a surrounding case. It can then be arranged multistage for greater proportions of compression. The compression is largely influenced by a centrifugal pump What is a centrifugal compressor - Centrifugal compressor is a dynamic machine. It achieves a pressure rise by adding kinetic energy/velocity to a continuous flow of fluid through the impellers. This kinetic energy is then converted to an increase in pressure by slowing the flow through a diffuser Ranging from the first high-pressure compressor for fertilizer to the most powerful offshore compressor, we have over 5,000 units installed worldwide since 1960.
