To prevent damage from cleaning agents and disinfectants, NORD developed the nsd tupH Sealed Surface Conversion System. This innovative solution permanently penetrates the surface of aluminum housings to create a surface seven times harder than the original with high resistance to corrosion, acids, and alkalis that will not flake or blister like paint. The treatment provides a smooth, easy-to-clean surface, and maintains the low weight of the aluminum, keeping the load on the automated system minimal and operation costs low. NORD’s nsd tupH complies with FDA Title 21 DCFR 175.300 and is the ideal solution for hygienic, wash-down environments.
