Their aerodynamically optimized plastic rotors make the energy-saving motors (ESM) even quieter, and the fact that they do not require painting means they are better for the environment too. With a figure of over 65%, the motor efficiency level attained by the energy-saving motors (ESM) is more than three times that of conventional shaded-pole motors.

In practice, it has often proven possible to reduce power consumption to less than one fifth of previously standard values – in the light of the fact that shaded-pole motors are not normally operated at maximum efficiency – so that energy-saving motors promise a rapid return on investment.

The W1G product range is intended for installation under the shelves of refrigeration and freezer cabinets. By contrast, the new K1G range was specially designed for the back wall of refrigerated display cases, where installation space is often at a premium. Thanks to its extremely shallow design, it even fits into small gaps, permitting 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 any energy savings make a big difference. Powerful GreenTech EC motors from ebm-papst provide the best possible basis for this. This is exemplified by the energy-saving W1G 250 fans and the new K1G 250, which already have a proven track record in sizes 200 and 230.
