SECTION 3 - MAINTENANCE (CONTINUED)
INNERGY TECH®
Cleaning the Wheel
In most applications, it is not necessary to clean the media
of the wheel because the wheel rotates. Incoming and
outgoing air streams are constantly blowing debris out of
the media during operation. If cleaning is needed, clean
the media with a vacuum cleaner or pressurized air. It is
not recommended to use any type of solvent or detergent
on the wheel because it may cause damage to the media
or the material used to build the wheel.
Adjusting Air Seals
The Innergy tech energy recovery wheels are equipped
with our AirLoop™ labyrinth seals facing the media, low
friction side seals along the depth of the rotor and S-type
labyrinth peripheral seals along the outer edge of the rotor
as shown on the seal general overview drawing (below).
While the side seals and peripheral seals are factory
adjusted and don’t need further adjustment, the AirLoop™
labyrinth seals should be verified prior to start-up and
adjusted if needed. See Figure 68 (below).
As illustrated in Figure 67 (right), the correct adjustment
of our AirLoop™ labyrinth seal is obtained by allowing it to
barely touch the media before tightening the screws. If an
initial gap can be seen between the seal and media, the
seal is installed too far and should be moved closer until it
touches the media. On the other hand, if any deformation
to the lips can be seen, it means the seal is installed too
close and should be moved back until the lips are straight
again.

ADJUSTMENT
FIGURE 68 - ERW SEAL LOCATIONS
It should be noted that the AirLoop™ labyrinth seal is
made of a special material which was specifically chosen
to make sure it could never damage the media. While the
best seal is obtained when the above steps are followed,
if installed too close, the media will simply use the seal a
little more. As the wheel turns, the seal will automatically
adjust itself to the wheel’s tolerance (approximately 1/32”)
for the smallest possible air leakage and become a non-
contact seal that will last throughout the wheel life.
