Free Rotating Retractor Provides 100% Cleaning Coverage for Ducts and Tanks

June 13, 2024
Alfa Laval's high-efficiency retractable cleaning device, the Free Rotating Retractor, provides complete 310-degree cleaning assurance in hygienic processing lines.

The Alfa Laval Free Rotating Retractor, a retractable cleaning device, provides complete cleaning assurance when cleaning ducts, tanks, and other confined spaces with hard-to-reach shadow areas.

Preparing hygienic vessels quickly and economically so that all interior surfaces are spotlessly clean and ready for production is easy with the Free Rotating Retractor. This retractable cleaning-in-place device remains sealed off from the product area during production, flush with the vessel wall. The spray head slides out, expelling cleaning media in a 310-degree-up spray pattern across the vessel surface. Upon completion of the cleaning cycle, the spray head retracts, and the vessel is production-ready.

The Free Rotating Retractor quickly removes residues from the interior surfaces of hard-to-clean vessels, limiting cross-contamination. It complies with FDA, EU, and China regulations while securing good manufacturing and hygiene practices at dairy, food, beverage, home & personal care, and other processing facilities.

For high-purity pharmaceutical and biotechnology processing lines, the Free Rotating Retractor UltraPure is the solution. A 3.1 documentation package for metal parts is available upon request.

It's easy to install, operate, and maintain due to its construction. To fully automate operation, pair two or more of these cleaning devices and Alfa Laval ThinkTop sensing and control units with an existing CIP system.
