A Clean Driving Zone" is an area designed and specifically dedicated within a manufacturing production facility or any industrial plant, which assists with the cleaning of lift-truck tires as well as other wheels from intra-logistic transport vehicles. CDZ's are currently installed mostly at automotive OEM's and their Tier 1 & 2 supplier networks. In recent years more industries have adapted a process to assist with "Clean Factory Solutions" and achieve a higher standard of technical cleanliness. Food & Beverage manufacturers have also started to implement a "Clean Driving Zone" at their sites to assist with disinfecting wheels to prevent contamination or cross-contamination.
