Diversey Care, a division of Sealed Air, creates a quality, innovative detergent/disinfectant system for North American commercial kitchens, on-time, on-budget, and made-in-America

OptifillDiversey Care, innovative pioneers in the commercial cleaning and hygiene business, turned to Wisconsin-based Knapp MFG., Inc. and Sussex IM to re-launch the manufacture of their North American supply of the Optifill™ system for manual ware washing.

Development of the commercial cleaning system, made by Knapp MFG and Sussex IM, was moved back to North America to provide Diversey Care’s customer base with a reliable supply chain for a high-performance detergent and disinfectant program that is precise, consistent, safe, and easy to -use and maintain.

Knapp MFG., Inc. is the leading precision molder of liquid dosing and delivery systems, and Sussex IM is the award-winning, one-stop source of design, engineering, lean manufacture and post-molding plastics-related operations for a wide range of global power brands.

The precision Optifill™ system developed for Diversey Care utilizes a sturdy, multi-piece, polypropylene design and was created with durability and recyclability in mind, to withstand repeated, harsh use in a typical commercial kitchen environment. 

“We were gratified to demonstrate how our U.S.-based capabilities deliver world-class, innovative products that truly benefit the end-user,” said Keith Everson, President, Sussex IM. “Our experience allowed us to reverse engineer and improve upon the product’s original design.  As a result, Sealed Air’s Diversey Care team realized supply chain efficiencies in terms of time and cost, as well as a first-rate product that benefits their commercial food customers.

“On-shoring,” Everson said, “is most definitely back.”

“We teamed our expertise in Precision Plastic Injection Tooling and molding with Sussex IM’s decades of plastics experience to create a superior U.S.-made commercial detergent and disinfectant system,” said Knapp MFG’s Vice President, David Horvath.  “Our seamless work is another example of how – when all factors are considered – the pendulum has swung back to domestic manufacturing.”

Diversey Care’s Optifill™ system is designed for easy, hassle-free use right out of the box, without complicated installation or training instructions.  It is one of the only non-wall-mounted systems that can deliver precision dosing and dispensing of ware washing chemicals, use after use.
