Why choose for Dertec Stainless steel gearboxes and motors


All Dertec stainless steel geared motors and stand-alone Electric motors are being made with laser engraved technical data on the frame thus eliminating hygienic and safety risks.


Tagplates on common geared motors are prime areas for bacterial growth. The small seem under the tagplates offers an ideal spot for bacterial growth. Tagplates will corrode, get damaged or can detach from the gearbox housing without knowing where the tagplate can be found back. This can also lead to traceability issues in your food production line.


IP Sealing

According to the IEC Norm 60529 the IP code consists of two digits. Generally speaking the higher the numbers the higher the protection. The first digit stands for ingress of solid or dust particles. The second digit is an important number for the foodindustry as it stands for the protection against water. Dertec Stainless steel geared motors are rated IP66 and can be rated IP67 or IP69. Please consult our salesteam for the correct IP grade matching your requirements.


Note: IP67 and IP69 are different test methods and intended to be for different industries. Please check the official Norm and understand the differences. For more information select the blue “more information box“.

Terminal box

Dertec Stainless steel geared motors and stand-alone electric motors are being equipped with a round terminal box. The terminal box is welded to the motorframe and has limited spaces to trap dirt or water. A carefully selected Dertec hygienic gland matching the cable diameter will offer a watertight hygienic solution.


Our new series Stainless steel motors will be equipped with a brand-new design terminalbox. The new terminalbox has a similar round design but can be turned around 360 Degrees to offer the best possible cable entry position. The new designed Terminal box offers double sealing against water ingress and hygienic protection by using new silicon hygienic seals between the cover and the base.
