Booster system for reliable seal gas supply

The reliability of gas seals de-pends on an adequate flow of clean dry gas at the seal. Gas supply systems take product gas from a higher-pressure stage of the compressor, filter the gas and use it to flush the seal. When the compressor is not running, the flow is interrupted and there is no source of high-pressure gas to protect the seal from contaminated prod-uct gas. This can pose a serious risk, because deposits at the seal can cause leakage or even damage the seal. In order to alleviate this problem, piston compressors/boosters driven by compressed air have been deployed in recent years to suck in filtered gas from the compressor, increase the pres-sure and use the gas to flush the seal. More and more end users are specifying booster systems to increase gas seal reliability. Piston compressors have a maximum service life of about 8,000 hours, are sensitive to dry gas, and they wear out when run continually. In contrast to conventional boosters, RoTechBooster of the EagleBurgmann group uses a radial fan which is driven by an electric motor via a proven EagleBurgmann magnetic coupling. There are no fast-wearing parts like the piston rings in piston compressors. The RoTechBooster is virtually wear-free, guaranteeing a high availability of the compressor system.
