Functional description

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 a conditioning system and using it to flush the seal.

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

The RoTechBooster incorporates an EBNM high efficiency magnetic coupling eliminating the need for an additional mechanical seal. Incorporating a magnetic coupling removes any possible additional system leak paths, eliminates emissions, increases safety for personnel and produces virtually wear free operation. Using a high efficiency design efficiently transfers torque, which delivers higher pressure ratings and reduced operating costs. This coupling design guarantees maximum RoTechBooster availability ensuring abundant seal gas flow through all operating conditions.
