Ljungström® RotaBrush™ Adaptive Brush Seals

THE MOST EFFECTIVE FULL CONTACT SEALING SYSTEM

Designed with flexibility and adaptability in mind, RotaBrush™ Adaptive Brush Seals offers a naturally conforming barrier that prevents air-to-gas leakage. Our innovative brush seals are capable of withstanding variances in gap size as well as surface irregularities, ensuring optimal performance day after day.

CONSISTENT

Tighter seal settings and hard-wearing brush filaments that are very forgiving of a broad range of conditions mean that RotaBrush™ Adaptive Brush Seals brush seals provide more continuous and consistent sealing even in irregular sealing surface conditions.

LONG-LASTING

Thanks to its clever seal elasticity which reduces drag and wear, RotaBrush™ Adaptive Brush Seals offers a long functional service life, which will extend over multiple outages and provide reliable sealing 2 to 5 times longer than standard seals.

RESILIENT

Designed to withstand even the most aggressive service conditions, RotaBrush™ Adaptive Brush Seals have several patented features that ensure reliable and effective sealing even in the presence of turndown or soot blowers.

REAP THE BENEFITS OF EFFECTIVE, LONG-LASTING AND CONSISTENT SEALING WITH LJUNGSTRÖM ADAPTIVE BRUSH SEALS

RotaBrush™ Adaptive Brush Seals offer 80% improved sealing capabilities, longer functional service life, and higher reliability compared to all other types of full contact seals. Our soft-contact brush seals are incredibly resilient and guarantee optimal performance so your plant can keep operating to its full capacity.

REPLACE CARTRIDGES WITHOUT DISTURBANCE

Developed in collaboration with Sealeze, RotaBrush™ Adaptive Brush Seals offer an innovative replaceable seal cartridge design, with a two-part system that allows for fast and easy replacement. The quick-lock holding tabs system secures the seal cartridge in place during service so you can easily replace the cartridge during an outage without disturbing the gap setting.

ENJOY LONG-LASTING RELIABILITY

ROTABRUSH™ Adaptive Brush Seals is made up of thousands of filaments nestled together to create a very tight seal and innovative impermeable, malleable inter-brush membrane that enhances sealing effectiveness up to 80%. Each of these filaments moves independently which dissipates stress and reduces drag and wear, extending your working service life and providing reliable sealing over multiple outage cycles.

DISCOVER THE RotaBrush™ Adaptive Brush Seals DIFFERENCE

With a range of innovative features, including a replaceable brush design and brush filaments offering less drag, RotaBrush™ Adaptive Brush Seals is a sustainable solution for sealing irregular sector plate and axial seal plate surfaces that will keep your plant operating efficiently, cost-effectively and at full capacity for a long, long time.

Our adaptive brush seals are a proven solution for reducing air to gas leakage. With sealing configurations available for a wide range of air preheater sizes, Adaptive Brush Seals offers enhanced sealing with lower drag and wear, as well as resilience and resistance to break-away failures.

With RotaBrush™ Adaptive Brush Seals your plant will:

SAVE ON FUEL - an adequately sealed air preheater improves plant efficiency, resulting in reduced fuel consumption

REDUCE YOUR CO2 EMISSIONS - using the RotaBrush™ Adaptive Brush Seals means you'll be burning less coal and generating less CO2 and other emissions

LOWER YOUR FAN POWER - reducing air preheater leakage leads to lowered fan power consumption and therefore to saleable MWs or recovered valuable fans margins

AVOID CAPACITY LOSS - prevent fan limitations that impact capacity output at the times when MWs are needed most, and an inability to deliver them is most expensive

IMPROVE YOUR APC PERFORMANCE - better control of your flue gas volumes and temperatures means your air pollution control equipment will perform more consistently and predictably

SAVE TIME AND MONEY - RotaBrush™ Adaptive Brush Seal's ingenious replaceable seal cartridge system means you can avoid the time-consuming and costly gap setting process
