Taking a radical step forward in fan design, ebm-papst has announced the release of new technology primarily used in ventilation and air conditioning applications.
The new low pressure centrifugal fan series known as RadiCal is also used in heat pumps, home ventilation with heat recovery, clean room ceilings and roof fans.
The development philosophy behind this technology is that the product must surpass its predecessor in terms of economy and environmental responsibility.
It uses EC technology including diameter sizes from 133 to 630mm.
A simple, mechanical one-to-one replacement of existing air conditioning solutions is possible using EC technology thanks to identical dimensions for most sizes.
Increased energy efficiency, continuous open loop speed control and high power density are part of the package, with short installation times.
RadiCal fans can also be speed controlled using 0-10V; sizes 280mm and above are also equipped with MODBUS. The motor's improved thermal management guarantees extremely high efficiency and 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 optimum flow regulation.
This avoids turbulence and flow separation, resulting in increased efficiency and extremely low noise.
RadiCal fans already far surpass the minimum legal requirements for electrically powered fans. The EU's Eco-design Directive 327/2011 stipulates the minimum efficiency level for new fans on the market driven by motors with an electric input power of more than 125 watts.
Their efficiency already surpasses the new MEPS industry standard for electrically powered fans.
