The unbeatable solution for reliable seal gas supply fl ow Relyonexcellence

RoTechBooster

The reliability of gas seals largely depend on having a continuous supply of clean and dry flushing gas. In dynamic mode, gas supply systems take process gas from a higher pressure level in the compressor, filter it and use it to flush the gas seal. This ensures effective protection of the gas seal against contaminated process gas. When the compressor is in slow-roll or a transient mode, however, the lack of flow in the machine interrupts the source of higher pressure gas. This is where EagleBurgmann RoTechBoosters come into their own. During this phase, which is highly critical for the gas seal, the RoTechBooster compresses the filtered flushing gas in the bypass of the clean gas rail of the clean gas panel and supplies it to the seal. This prevents collections of dirt deposits at the gas seal which may result in leaks or even damage. The volume of gas is monitored by a flowmeter.

AdvantagesEagleBurgmann’s RoTechBooster provides a reliable clean gas flow whenever transient conditions occur. This ensures that clean dry gas is provided to the dry gas seals, resulting in the reliability you expect. No rubbing shafts or seals and no sliding parts means less parts to maintain. Centrifugal solutions are known to be very reliable and eliminate the pulsation in the gas flow• No oils required for lubrication • No limitations for lengths of operating times Hybrid ceramic bearings and absence of shaft seals provide reliability and longer maintenance cycles with less contacting parts. The bearings will not require any lubrication, eliminating any concerns with lubricants contaminating the gas stream

Features• Centrifugal design. High reliability and availability • High efficiency magnetic coupling:• 95 % less eddy currents, reduced power consumption, reduced heat generation

• Extended life. 3-4 times greater than current boosters (>24,000 h)

• Environmentally safe. No leakage to the atmosphere • Simple set-up, easy to operate, virtually maintenance free • Flexible driver systems. Electric motor standard - steam/air optional

• ATEX Certification on request • Various model available, depending on systems requirements

Importantnote

All the technical specifications are based on extensive tests and our many years of experience. However, the diversity of possible applications means that they can serve as guide values only. It should be noted that the extremal values of each operating parameter cannot be applied at the same time because of their interaction. Furthermore, the operating range of each specific product depends on the respective shaft diameter, materials used, mode of operation and on the medium to be sealed. A guarantee can only be given in the individual case if the exact conditions of application are known and these are confirmed in a special agreement. When critical conditions of operation are involved, we recommend consulting with our specialist engineers.
