Centrifugal compressors compared to other compressors are expensive piece of equipments. These are fluid flow dynamic machines which are required for compression of gasses. Centrifugal compressors are constructed according to 2 configurations. These are either horizontally split construction or barrel type construction. Integrally geared centrifugal can operate at speeds much more than any other compressors. These are more reliable compressors which are targeted toward large scale factory level enterprises.
