TDC 584 Neutralisation Cabinet
Conditioning cabinet TDC 584 to discharge air filter and air filter media by isopropanol vapor according to ISO 16890-4
The harmonization of international testing standard ISO 16890-4 requires neutralization of tested filter element by Iso-propyl-alcohole (IPA) treatment. Therefore a suitable test cabinet for filter discharging is needed.
The solution proposed in ISO 16890-4, chapter 7 requires a large amount of hazardous substance with approximately 1 l of liquid IPA, whereas particularly the handling of the trays filled with liquid IPA is risky. Furthermore large quantities of IPA saturated air enter the laboratory after opening the cabinet, which is a sanitary as well as a safety-related problem. It also requires an air extraction of the complete laboratory area.
Due to these problems, Topas decided a new cabinet for the filter conditioning according to ISO 16890-4.
Due to these problems, Topas decided a new cabinet for the filter conditioning according to ISO 16890-4.
