Rotary heat exchanger – disinfection & cleaning
according to VDI 6022
Rotary heat exchangers are among the most effective devices for heat recovery from room air or process air. The energy-efficient systems are installed in the ventilation technology of residential and office buildings and are also used in the industrial sector. The professional disinfection and cleaning of rotary heat exchangers is therefore a critical task that is regulated in detail according to the VDI 6022 guideline.
Fouling & wear of rotary heat exchangers
During operation, the fins of the rotary heat exchanger become soiled over time with deposits of fine dust and dirt. As a result, the efficiency of the system decreases noticeably. In ventilation systems with strong filtering, this process takes much longer – this means that the filters have to be changed regularly. In the course of disinfection and cleaning according to VDI 6022, we can directly repair or replace defective parts in ventilation systems .
One of the advantages of rotary heat exchangers is their insensitivity to coarse or dry contamination . By changing the air direction, leaves, coarse dust or insects, for example, are simply blown out again. Fine particles and humidity are the real threats that have to be eliminated during cleaning and disinfection according to VDI 6022.
Rotary heat exchangers in commercial operation are often exposed to increased loads. In chemical plants, for example, corrosive material can attack ventilation flaps and filters. In canteen kitchens or laundries, high humidity is a problem because it can promote the formation of harmful fungi and germs in the ventilation ducts.
Consequences of soiled rotary heat exchangers
Regular hygiene inspections as well as professional disinfection and cleaning of the heat exchanger are indispensable for various reasons:
