6.5 Sealing system
Both non-contact sealing on wheel peripheries and brush sealing middle beam are maintenance-free but their con-
dition must be checked every year. During the inspection, check their tightness and overall visual condition. Non-con-
tact seals cannot be flipped, rolled or pierced at any place (Fig. 6.8, Fig. 6.9).

Correctly fitted sealing of the Rotary Heat Exchanger.
Swiss Rotors wheels are equipped with durable sealings which should last lifespan of the entire product if properly
used and maintained. If sealings are damaged, please contact our service immediately. A damaged seal may cause
efficiency deterioration, mixing of an air flows and unwanted leakages in the system, especially in environment with
hygienic requirements.

Examples of broken and incorrectly fitted sealings.
To install the new sealing, it is obligatory to start with cutting off the old sealing with sharp knife all along the circum-
ference of the energy recovery wheel (Fig. 14). Try to cut the sealing as close to the recovery wheel matrix as possible.
Don’t use force, don’t pull the sealing, do not damage the matrix of the recovery wheel – caution must be preserved.
