CIP/SIP as one of main challenges of the process industry

Freudenberg Sealing Technologies offers highly resistant materials that reliably withstand demanding CIP/SIP media and processes.

CIP/SIP (Cleaning In Place/ Sterilization In Place) is a common process in the food and beverage industry. Its key advantage is a fully automatic cleaning process that eliminates the need for disassembling equipment and machine parts – and for a final visual inspection. But CIP/SIP requires special components that withstand cleaning media and high temperatures.

Freudenberg Sealing Technologies offers seals made of special materials suited to these conditions. They are highly resistant to aggressive cleaning agents based on acids, lye and peroxide as well as high temperatures (steam as high as +284 F). The product portfolio also includes screw systems and other components that are free of dead space.

Using the highest recommended operational concentrations and temperatures Freudenberg has carried out extensive exposure testing. This makes our database for CIP/SIP cleaning agents consisting of over 200 compositions and 5,100 measurements a solid basis for the CIP/SIP Guide. It offers you the possibility to find the right material for the below explained cleaning agents.
