Clipdisc CIP sanitary tank washers from Chemdet Inc. feature an ultra-hygienic, patented design that delivers vigorous cleaning action with a high-density 360-degree spray pattern. Engineered to meet rigorous USDA, FDA and 3-A material and design standards for sanitary food and dairy processing, the maintenance-free clipdiscs eliminate screw threads, ball bearings and other debris trapping orifices. They are made with just one moving part, a chemically inert, food grade polyvinylidene fluoride disc that rotates on a 316 stainless steel shaft. The unique Clipdisc design utilizes the cleaning fluie to drive, hydraulically balance and lubricate the precision-shaped disc.
