CIP/SIP as One of the 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 that it constitutes 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 can 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). Our product portfolio also includes screw systems and other components that are free of dead space.

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