Our gear units and motors can provide additional protection against typical corrosive agents in industrial environments, such as moisture, oils, dirt and chemicals, than what is provided as standard. Additional treatments and special materials allow these devices to be used even in extreme conditions. Use our drives in any atmosphere, from those with low moisture and contaminants to environments with regular wet cleaning using acidic and caustic agents.

Our surface protection levels range from standard to levels OS1* to OS3*. With the ASEPTICplus® package, OS4* is set as standard.

The XCO drive package is even going further. The innovative tin-nickel surface protection prevents coating from coming off and provides a stainless steel like appearance. This XCO surface protection is an essential feature of the XCO drive package. In addition, the XCO drive package includes among others stainless steel screws, IS connectors, and motors in IP69K degree of protection.

*Similar to corrosivity categories C1 (negligible) to C5-I (very high).

It is not only our standard components for which optional preventive measures are available. Our aseptic motors of the DAS.. series with XCO and ASEPTICplus® drive packages are optimized for use in sensitive, hygienic production areas. Our stainless steel gear units of the RES.. and KES.. series complete the range of products for cleaning-intensive areas. The surface made of high-quality stainless steel is resistant to acid and alkaline, and is easy to clean.
