Energy-saving motors are synonymous with ecological efficiency

Thanks to an aerodynamically optimized plastic rotor, energy-saving motors (ESM) are even more quiet-running, and are better for the environment as they do not require painting. With a figure surpassing 65%, energy-saving motors (ESM) achieve a motor efficiency level more than three times higher than that of conventional shaded-pole motors.

In practice it has often proved possible to reduce the power consumption to below one fifth of the values that used to be normal in the past, as shaded-pole motors are not usually operated at maximum efficiency – which means that this investment quickly pays for itself.

Greater efficiency

The fact that less heat is generated in operation, and therefore less heat has to be dissipated to the surrounding area, also helps to enhance efficiency. Energy-saving motors (ESM) are available with outputs of between 5 and 35 W, for operation with a 230 V or 115 V power supply, and feature additional functions such as automatic night-time reduction to a second operating speed.

Economical refrigeration day in, day out

Energy-saving fans for refrigeration cabinets

The W1G product range is intended for installation under the shelves of refrigerated and freezer cabinets. By contrast, the new K1G range was specially designed for the back wall of refrigerated displays, where installation space is often at a premium. Thanks to its extremely shallow design, it even fits into small gaps and so permits optimum operation.

Energy efficiency has become one of the most important topics in virtually all areas of life. Air conditioning and refrigeration systems in particular tend to be in operation for long periods and so offer tremendous potential for saving energy. Powerful GreenTech EC motors from ebm-papst provide the best possible basis. This is exemplified by the energy-saving fans W1G 250 and the new K1G 250, which already have a proven track record as size 200 and 230 versions.


Energy-saving motor speed programming with the hand-held Programmer

 Programming unit

This programming unit, designed specially for use in production or in the field, provides a user-friendly navigation menu for extremely simple programming of the two pre-set speed levels of the energy-saving fans. An automatic switch-off function extends the battery service life. Software updates can easily be downloaded with a Mini-USB connector. Batteries, programming cable, and operating instructions are included in the scope of delivery.

As a supplement to the functions so far provided by the energy-saving motor product range, these extra features permit demand-based control of the installation as a whole, thus further enhancing overall efficiency. The energy-saving fans are designed for long-term, maintenance-free operation. They achieve a service life generally in excess of 60,000 hours, depending on ambient conditions. The cost of installation in new devices or retrofitting in older devices is soon more than offset by the amount of energy saved.
