Stainless steel motors SBN/SBH - new design

Rehfuss has long been involved in the development and design of drives for use in areas where hygiene, cleanliness and characteristics for easy cleaning are important. For this reason, we have been offering our customers a stainless steel motor for many years now and placing it very successfully in the respective industries. Since some time, customers have no longer been satisfied with just a standard stainless steel motor or a stainless steel gearbox. Today the trend is more and more towards drive concepts in HYGIENIC DESIGN. We have now revised our motor sizes 71 with the help of our extensive experience in the field of stainless steel drives and in compliance with the corresponding EHEDG guidelines and now can offer electric motors in HYGIENIC DESIGN to our customers.

SBE - SMOOTH BODY E (stainless steel) stainless steel motor

The SBE execution is a stainless steel motor for hygienic applications (packaging industry, pharmaceutical industry, food industry, ...). It is easy to clean and it is designed that it is very difficult, that dirt can deposit on it. It also is very resistant to aggressive media.

SBH - SMOOTH BODY H (hygiene) stainless steel motor

The SBH execution is based on the SBE execution and has basically the same characteristics as the basic model. In addition, however, this variant has additional modifications that facilitate its use in the processes (for example directly near the foods to be processed). For this, the EHEDG guidelines were explicitly taken into account when designing the products.
