Air-conditioning services

When conducting field campaigns, the first step is to measure the characteristic values of air conditioning systems.

An extensive pool of instruments is available for this purpose. In addition, convection volume flows that are based on thermal loads and are frequently influenced by transverse flows are identified which cause the ingress of hazardous substances in the production process (gases, dust, aerosols, etc.).

If necessary, associated accredited meter operators determine the quantity and concentration of hazardous substances at the workplace (MAC).

The main task is to determine the key planning figures for thermal and substance mass flow rates, since this knowledge will be essential for balancing, selection, and planning of technical exhaust and supply air components and of the entire plant.

Basic engineering

Basic engineering encompasses the assessment and classification of all findings collected in the course of current-state analyses for the specific application. Based on the key planning figures determined by ETS, a custom technical system concept can be developed.


ETS systems engineering is always dimensioned individually – for safe compliance with the occupational exposure limit value of hazardous substances (AGW/OEL), comfort criteria and energy-efficient operation. The ETS exhaust and supply air components, which are designed and constructed for the specific loading condition, are a determining factor for the quality of the entire system.


The service range of the industrial air technology competence center comprises planning services of the HOAI stages 1–4. Further planning stages are offered in cooperation with the respective ETS sites.
