DGS-PCS is a dry-running gas seal,it is a single end gas seal,cartridge design,uni-directional or bidirectional .The complete seal assembly consists of a stationary seal , rotation seal and welded metal bellows. Cryogenic dry gas seals play a critical role in LNG applications, where equipment must operate reliably at extremely low temperatures. By effectively controlling and minimizing the escape of process gases, cryogenic dry gas seals help protect system safety and operational stability. Their robust design supports long-term performance under cryogenic conditions, making cryogenic dry gas seals a key factor in maintaining efficiency and reliability across LNG facilities.Can be used as a replacement for John crane Type 285.
