ROTARY EXCHANGER - RO

The main part of the heat recovery RO section is a rotary heat regenerator for recovering heat
from the exhaust air. Depending on the version, the rotor of the exchanger may be a
condensating one or a hygroscopic one. Exchangers with a condensating rotor are used in
systems, where humidity recovery is not important. The exchanger can be adapted for operation
with constant or variable rotational speed (in this case the exchanger).

The efciency of the recovery of heat and humidity may be controlled by
changing the rotation speed of the can be controlled.
