A large quantity of modern process gas compressors is equipped with Dry Gas Seals. A Dry Gas Seal Supply System is used to make sure that the gas entering the Dry Gas Seals is conditioned correctly to maintain optimal seal health. Filtration is an important part of Seal Gas Conditioning, as it ensures no particulate or liquid contaminations to enter the Dry Gas Seals and cause pre mature seal failure.
