The complete RadiCal series using EC technology now includes sizes from 133 to 630. A simple, mechanical 1:1 replacement of existing AC solutions is possible using EC technology thanks to identical dimensions for sizes of 190 to 250. This allows the advantages of EC technology to be utilized, such as energy efficiency, continuous open loop speed control and high power density, with just a small investment in time and money. In addition, the 250 size was supplemented with a variant with increased power. RadiCal fans can be controlled using a voltage anywhere from 0 to 10 V; from size 280 onwards they are even equipped with MODBUS by default. As far as the motor is concerned, its improved thermal management guarantees extremely high efficiency and also ensures high IP protection.
The impeller made of high-quality composite material provides high mechanical strength and resistance to ambient influences. In addition, using composite materials allows flow regulation to be optimally designed. This avoids flow separation and turbulence in the flow channel, which leads to increased efficiency and extremely low noise emissions.
In terms of efficiency, RadiCal fans already far surpass the minimum legal requirements for electrically powered fans. Eco-design Directive 327/2011 EU stipulates the minimum efficiency level for new fans on the market driven by motors with an electric input power of more than 125 watts.
In addition to traditional applications in ventilation and air-conditioning technology, RadiCal fans are used in heat pumps, home ventilation with heat recovery, clean room ceilings and roof fans.
