Notes
One of the biggest challenges in operating centrifugal compressors with dry gas seals is seal gas supply contamination. Liquids or particles in the supply gas are the main causes of shortened seal life. With special features, the RoTechSeal increases the lifetime of a normal seal in a wet and dirty environment. The robust seal features will be defined case-by-case based on the operating conditions and failure analysis.
