Your advantages

Avoid dust
as the motors do not have any cooling fins and dirt almost no dirt sticks to their almost entirely flat surface.

Stop germ distribution
because the aseptic motors are convection-cooled they cause no air turbulences and, consequently, do not distribute germs and bacteria.

Aseptic motors: Smoot and easy to clean

We develop and produce aseptic motors with special equipment for hygienically sensitive production areas. The DAS.. series is ideal for use in your sensitive production areas such as in the pharmaceutical, cosmetics or food and beverage industry. Even if an absolutely clean production environment is prescribed, you can safely use the motors in connection with the ASEPTICplus® or XCO drive package.

Two main features of the DAS.. series motors:

In contrast to standard motors, which are equipped with cooling fins, the surface of our aseptic motors is as smooth as is possible. This makes them virtually dirt-repellent.

Standard motors have a fan, our motors do not: they are convection-cooled. This means that they cause no air turbulences and, consequently, do not distribute any germs and bacteria.

The cleaning processes for the production system that are essential in those types of production areas are just as problem-free and practicable. Equipped with the appropriate surface and corrosion protection measures, you can safely apply aggressive cleaning agents and disinfectants to these motors with drive package ASEPTICplus® or XCO drive package. This is because the surface protection and materials used withstand the regular cleaning procedures.

So put your trust in drive technology for hygienic areas made by SEW-EURODRIVE.

Always the right choice

The drive technology used encounters special ambient conditions in hygienic areas, and should therefore be resistant to aggressive cleaning agents and disinfectants. You are making the right choice with our DAS.. series motors because they are protected against:
  • Food and beverage industry
  • Chemicals and pharmaceutical industry
  • Applications in dry hygienic areas e.g.
    • PET bottle conveyor belts
  • Applications in hygienic production areas e.g.
    • conveyor belts in meat processing
