OptiFlex Radial Seals include a number of intelligent features such as a preloaded flexible leaf.
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.
With unique features designed to meet your needs, OptiFlex Radial Seals offers ultimate flexibility.
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.
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.
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.
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.
OptiFlex Radial Seals offers an optional hardened wear tip that can be adjusted to the specific application.
Your safety is also considered, with a holding bar and backing bar that limit loads and provide protection from sootblowing damage.
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
Utilize the latest generation of our flexible seal technology to significantly lower your hot end air to gas radial leakage in your Ljungström® air preheater
