Hygienic, practical, efficient
Energy-saving GreenTech EC fan for smaller unit coolers.

Cool unit

Thanks to the GreenTech EC motor, the new unit cooler energy-saving fan for evaporator applications sets new standards with its compact design and high efficiency levels. And this plug and play solution offers maximum installation flexibility, so it’s ideal for retrofitting as well.

All the advantages at a glance

  • Up to 40% lower energy consumption than AC solutions
  • Simple installation thanks to plug & play
  • Version with two settings for day and night-time operation
  • High degree of protection IP54 and integrated plastic grill for safe cleaning and optimum hygiene


The characteristic features of the fans, developed specially for evaporator applications, are great efficiency, outstanding reliability and a long service life. They were designed as complete units.


When using the GreenTech EC motor combined with the tried-and-tested HyBlade fan impeller, energy savings of up to 30% can be made compared to evaporator fans with conventional AC motors.


Installation using the one-piece mounting arms is made relatively simple by the flexible mounting hole circles. This design ensures that customers can retain the outward appearance of existing applications using the guard grill. Even for retrofits, the evaporator unit does not have to be disassembled.
