Dry gas seal rack DGSR is dedicated system for sealing of gas compressors. Main purpose is to provide dry, clean gas at specified parameters such as flow, pressure and temperature during start-up, normal work and settle out. Our systems are designed to fulfilled all requirements stated in API 614 (including final client’s specification) and standards like EN, ASME and GOST. It can be places in harsh environments, explosion zones or extreme low temperature. Racks can be provide with CE (for Europe Union) or EAC (for Eurasian Custom Union) mark. For Eurasian Custom Union we also provide all necessary documentation such as technical passports or justification of safety.
