Cooperation with Schweitzer Chemie in the area of chemical sterilisation

For energy conservation reasons, state-of-the-art paint finishing facilities are operated by means of an ever-increasing portion of circulating air. This trend is being promoted by the increasing use of water-based paint systems and the high degree of automation during the application of the paint and thereby the removal of the need to adhere to occupational exposure limit values for breathing air. Depending on the extent of contamination of the circulating air, germ formation within the circulating water may, even if operation complies with specifications, reach a level at which physical sterilisation methods (UV immersion lamps/UV reactors) do not suffice for operation in accordance with VDI 6022. In such cases of high germ infestation, we now offer supplementary chemical sterilisation methods (hydrogen peroxide, chlorine dioxide) in cooperation with Schweitzer Chemie. In the case of old systems, the retrofit is carried out via a separate dosing station. In the case of new systems, we recommend implementing the chemical sterilisation equipment directly on the humidifier’s operating side.

Our partner, Schweitzer Chemie, has been operating in the field of water processing and treatment for many years. Its range of products includes water softeners, filter systems, desalination units, dosing units for chemical water treatment, UV sterilisation systems and conductivity-driven elutriation systems. Schweitzer Chemie also provides a wide range of chemical products for water treatment as well as for cleaning/disinfecting systems in contact with water. Firma Schweitzer has a nationwide service network for installation, commissioning, maintenance, inspection and professional cleaning of water-bearing systems. The company’s own laboratory enables a fast and reliable analysis of water quality. The analysis results provide the basis for a targeted selection of the appropriate chemical products for cleaning the systems and disinfecting the water in operation. Schweitzer Chemie also works, in this regard, with accredited samplers and analysis laboratories.
