EC axial compact fans provide 79 % energy savings in control cabinets

Whether in a control cabinet, in refrigeration technology or in filter fans - high demands are always placed on the fans used. Because many of these devices are operated continuously for years, reliability and service life are at a premium. The overall service costs, meaning the power consumption over the years, are likewise critical.

ACi 4400 axial compact fan

The ACi 4400 axial compact fan is based on an electronically commutated drive. One advantage is that with corresponding motor electronics, up to approximately 80 % lower consumption than classic standard AC fans can be attained. Another advantage is that the electronics make the motor, and thus the fan, versatile. With their wide operating voltage range from 50 to 265 V (50/60 Hz), they are suitable for all worldwide mains supply networks.

In number terms, the ACi 4400 saves approximately 1,300 kWh over an AC fan in 10 years of continuous operation. The big brother, ACi 7200, achieves a savings of 2,500 kilowatt-hours in the same timeframe. If we assume energy costs of 0.12 EUR/kWh, this means monetary savings of 156 or 300 EUR during the operating time. Thus in continuous operation, the small fans are amortised after only 3 months, and the larger ones after 5 months. From then on, they save cash money every time they rotate.
