Holder System

A properly designed seal is essential for easy installation. The patented Sealeze design makes replacing worn seals quicker, easier and less costly than other seals.

Sealeze adaptive air preheater brush seals - Holder System

Sealeze adaptive air preheater brush seals are constructed of corrosion-resistant stainless steel and are designed to install just like OEM seals, but with a smaller gap. When it’s time to replace the seals, the patented, replaceable seal cartridge design allows fast and easy replacement.

Because it is a 2-part system (brush seal and holder), once the system is installed and aligned, in future outages the brush seal can be replaced in about half the time it takes to replace the OEM seals, and at significantly lower cost. (You only replace the brush, not the holder!) Since the holder remains in place, the time-consuming process of realignment is eliminated. With our system, the holder has already been set and locked in place.

Our quick-lock system holds the brush seal securely in place during service, but during the outage allows the brush to be removed and replaced quickly without disturbing the gap setting. The only tools needed for brush seal replacement are a screwdriver and large jaw pliers…no cutting, grinding, torching or welding.


How the Quick-Lock System Works


Tabs are cut into holder and bent inward.

An edge is created inside the holder. When the brush is inserted,
it butts against the edge locking it in.

The brush is easily removed by lifting the tab with a screw driver.
