Powerful motors for big fans

Fan impellers with diameters of one or two meters are often driven by AC motors. However, by the time the next stage of the Ecodesign Regulation for fans comes into force, many of these solutions will no longer meet the increased requirements. The suitable alternative will then be new high-performance EC external rotor motors that operate at high efficiency levels. »

Roof-top data

The trend toward huge logistics centers presents new challenges for air conditioning systems. And another important criterion for the online mail order company Zalando is data acquisition.

Spinning off the grease

Hovs Hallar, a restaurant in southern Sweden, was looking for a new way to prevent grease buildup in its exhaust ducts. The solution it found was TurboSwing, which flings grease droplets to the side before they reach the duct.»

Smart electronics cooling for industrial applications

In control cabinets hot spots can arise, which can reach temperatures of over 90 °C and cause the destruction of sensitive electronics. Filter fans, units that combine fans and dust filters, can help by conveying excess heat out of control cabinets and electronics housings while also preventing the ingress of dirt particles.»

Improving efficiency with EC motors

Not only do the latest electronically commutated motors (EC motors) consume much less electricity, they are usually considerably more compact at equal or even higher power output. Their use in household appliances provides an example of the resulting benefits for machinery and equipment. A few scenarios described below show the advantages.»

Local heating supply reduces heat losses and costs

A modern local heating station operated with gas premix technology can now provide up to 2 MW thermal output – equipped with a single boiler. Premix technology reduces the emission of pollutants and, in combination with an EC motor with a broad modulation range, the environmental impact is minimal.»
