GCU Centrifugal Seal Gas Booster
Gas Conditioning Unit for Non-contacting Gas Seal for Turbo Compressors
The John Crane GCU Seal Gas Booster delivers differential pressure and gas flow across the seal faces to ensure the gas seals remain in optimum operational condition and equipment is always ready, allowing for trouble-free start-up, the first time and every time.
Reliable dry gas seal performance is dependent on a constant supply of clean seal gas at a pressure above that of the process, but when the compressor is stationary, there is no pressure differential within the gas seal support system to ensure clean gas flow across the seal faces.
