Energy-saving fans
and energy-saving motors (ESM) 

Optimum solutions
for refrigerated display cases

All the advantages at a glance

Reduced heat loss saves even more energy – with a life expectancy surpassing 40,000 hours The compact design allows space to be saved and, above all, facilitates simple installation.

Motor speeds can be adjusted via a programming interface or controlled as required during operation using the optional ESM plug-in module.

Perfectly coordinated individual components! 

The energy-saving motor is the epitome of ecological efficiency

Their aerodynamically optimised 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.

Greater efficiency

A further factor in attaining greater efficiency is reduced self-heating during operation, which means that less heat has to be dissipated to the surrounding area. The energy-saving motors (ESM) offer outputs between 5 and 35 W, operate at 230 V or 115 V power supply and provide additional functions, such as automatically adopting a lower, second operating speed at night.

Air performance of K1G 250 and W1G 250

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.

Speed programming

Speed programming

This programming unit, designed specially for use in manufacturing or field service, has a user-friendly navigation menu that allows the energy-saving fans’ two pre-set speed levels to be re-programmed very easily. An automatic switch-off function ensures a longer battery service life. Software updates are easy to download with a mini USB connector. Batteries, programming cable and operating instructions are included in the scope of delivery.

Together with the functions already provided in the energy-saving motor product range, these additional features allow the entire system to be controlled based on the demand, allowing even better overall efficiency levels. The energy-saving fans are designed for long, maintenance-free operation. Depending on the ambient conditions, the service life is generally in excess of 60,000 hours. Thanks to the great energy savings, installation soon pays for itself, both in new units and in retrofits.

Plug-on interface module

Plug-on interface module

The plug-on interface module (ESM+) makes it quick and easy to add a 0-10 VDC control input and a +10 V voltage output (10 V, max. 1.1 mA) to the energy-saving motor. The energy-saving motor can then provide a direct power supply, e.g. for an external pressure or temperature sensor. There is no need for an additional, external power supply. The interface module ESM+ also supplies a tach signal for speed monitoring.

Energy-saving fan for 24 VDC low voltage

Energy-saving fans for 24 VDC low voltage are now available for refrigerated cabinets with low-voltage LED lighting. This version of the ESM features an integrated 0-10 VDC control input for linear speed control and a tach signal for speed monitoring. No interface module is required for this.
