Rotary heat exchanger
The safety switches must be switched off and locked after the unit has been switched off
before starting any service work.
Function
The rotary heat exchanger is a regenerative aluminium recovery unit that recovers
heat/cooling between the supply and extract air ducts. Outside air and extract air flow
through the rotor in counter-flow. The rotor consists of a large number of small ducts,
which means that it is very important to check, clean and care for the rotor and air filter.
Stopped or impaired function may cause considerable heating and/or repair costs.
The rotor normally self-cleans by switching the air direction when the rotor goes in or
out of the intermediate plane. The rotor is equipped with a blow-out sector that prevents
the extract air from flowing in to the supply air during rotation. It is important for the
blow-out function that the extract air part has a greater underpressure than the supply air
part. There should be 20–30 Pa greater underpressure on the extract air side.
The rotor motor and gear and the rotor shaft are permanently greased and do not need to
be lubricated.
Check
1. That the surface of the rotor is free of dirt.
2. That the rotor can be easily moved by hand and that there is no noise.
3. That the brush strip is intact and tightly secured.
4. That the rotor belt is intact, tensioned and free of cracks/damage.
5. That the rotor motor and pulley are undamaged and clean.
Corrective action
1. Before cleaning, first loosen the rotor belt. Vacuum with a soft brush while spinning
the rotor manually or use compressed air to blow the area clean.
