Heat recovery systems (HRS)
Rotary heat exchanger
In the case of rotor casings supplied in two parts, the rotor casing must be bolted together in
accordance with the rotary heat exchanger manufacturer's specifications before the accumulation
mass is installed. For this purpose, it is necessary to lower the upper rotary heat exchanger case
accordingly.
Rotor assembly
If the rotor assembly is done by the customer, the connection between the rotary heat exchanger and
the casing must be sealed properly (e.g., with permanently elastic joint sealant).
Sealing strips
Check sealing strips for compression. They must be pushed as close as possible to the accumulation
mass, avoiding direct grinding even under operating pressure conditions.
Bearing
Generally, the bearing of the rotary heat exchanger is aligned in the factory. It may need to be
adjusted. Follow the manufacturer's operating instructions.
Drive
1. Open the inspection hatch at the marked rotary heat exchanger corner.
2. Check whether V-belt is sufficiently tensioned by the tensioning device. If necessary, shorten
the V-belt as follows:
3. Open the joint lock.
4. Shorten endless V-belts accordingly.
5. Close the joint lock.
6. Close the inspection hatch.
