Ljungström® OPTIFLEX™ RADIAL SEALS

REDUCE YOUR HOT END AIR TO GAS RADIAL LEAKAGE TO AN ALL-TIME LOW

Thanks to LJUNGSTRÖM’s innovative OptiFlex™ Radial Seals, which utilize the latest generation of our flexible seal technology, you can now lower your hot end air to gas radial leakage in your Ljungström® Air Preheater to historically low levels.

INNOVATIVE DESIGN

OptiFlex Radial Seals include a number of intelligent features such as a preloaded flexible leaf.

BUILT TO LAST

Due to a reduced contact force and minimized wear of both the seal and sector plate, OptiFlex Radial Seals offers a prolonged life of up to three years.

CREATED WITH YOU IN MIND

With unique features designed to meet your needs, OptiFlex Radial Seals offers ultimate flexibility.

OptiFlex™ Radial Seals

FACE THE CHALLENGE OF MAINTAINING AIR TO GAS LEAKAGE HEAD ON

For far too long, air preheater owners and operators have had to battle with maintaining their air to gas leakage within acceptable levels for efficient plant operation. Now, OptiFlex Radial Seals means you can ensure your plant is operating at optimal efficiency with minimal effort.

DESIGNED FOR AIR PREHEATERS WITH ACTIVE LEAKAGE CONTROL

Created explicitly for air preheaters that operate with active leakage control systems that adjust the sector plate position to follow the rotor movement during operation, OptiFlex Radial Seals are specifically developed for use in the hot end of your rotor.

UNIQUE ANGULAR MOUNTING ARRANGEMENT

OptiFlex Radial Seals has a unique angular mounting arrangement to the rotor diaphragm plate to reduce the contact forces of the flexible seal leaf on the sector plate.

AN EFFECTIVE AND LONG-LASTING SOLUTION

Our renowned air preheater design knowledge, operational experience, and dedication mean that we can offer you our flexible and patented seal technology that will transform the operation of your plant. Designed to eliminate the radial seal gap and provide the lowest leakage, OptiFlex Radial Seals offers light interference and negligible wear of both the sealing surfaces and actual seal, delivering a flexible and affordable solution that will serve you well for years.

SAFETY

Your safety is also considered, with a holding bar and backing bar that limit loads and provide protection from sootblowing damage.

HOW Ljungström® OptiFlex™ Radial Seals CAN ENHANCE YOUR OPERATIONS

OptiFlex Radial Seals flexible leaf accommodates pressure differentials and encourages deflection away from the sealing surface, therefore providing maximum leakage reduction

Reduced cyclic pressures also lead to a longer operating life and help avoid the premature failure of the flexible leaf portion
