Adequate, clean, and dry gas flow at the seal governs seal reliability. During normal operation, this is achieved by taking product gas from a high-pressure stage or discharge of the compressor, flowing it through filter(s) and using it to flush the seal.

When the compressor slows or is at pressurized standstill, the gas flow is interrupted and leaves the seal(s) unprotected from contaminated product gas. This poses a serious risk, because unfiltered product gas leaves deposits at the seal, leading to high seal leakage or even seal failure. In order to alleviate this problem, boosters are utilized to draw gas from the compressor and flow it through filters providing clean and dry gas to the seal(s).

Using the RoTechBooster, which incorporates the NMB high efficiency magnetic coupling, eliminates the need for an additional mechanical seal. This removes any possible additional leak path in the system, eliminating emissions and increasing safety for personnel. The coupling design also achieves the most energy efficient torque transfer for further minimizing operating costs along with the virtually wear-free operation to guarantees maximum availability for ensuring delivery of abundant seal gas through all operating conditions.
