Rotary Heat Exchanger Block Alignment
Warning:
Poor and/or incorrect installation of the rotary heat ex
-
changer block can result in costly repairs. It will result in
rotor displacement, which will influence the tightness and
service life of the assembly. Misalignment can be caused
by improper handling during transport or failing to observe
the conditions for correct installation. To check heat ex-
changer rotor fouling, it is necessary to perform regular
monitoring of the heat exchanger rotor pressure loss. The
heat exchanger rotor pressure loss must not exceed 15%
of the pressure loss value measured on a new rotary heat
exchanger. To enable regular servicing, maintenance,
guarantee and post-guarantee service, it is necessary to
provide a service access from both sides of the heat ex-
changer's rotor.
