Extraction of welding and other process fumes as well as steam and heat results in a good “work climate”. Venti Oelde develops total solutions for this for machines, processes, workplaces, cabins, rooms and workshops of all sizes. For example, in industrial printing processes, the discharged air may be loaded with solvents, moisture, odours and excessive heat. Our highly effective systems reliably clean the flow of discharged air. The heat energy contained can be efficiently recaptured by a heat exchanger.
