The customer, in this case, needed protection for access to an ATEX-rated dust production zone of raw material with transport carts. The installation of the WZ mat ( https://www.acsupply.it/en/products/cleanroom/item-359 ), for a coverage of approx. 6sqm, reduced the conveyance of dirt within the ATEX zone, by the wheels of trnaspallets and forklifts as well as by the operators’ shoes. The WZ mat offers no obstruction or slowing down of the transit of means of transport and at the same time is washable like a normal resin floor with a scrubber-dryer.
