The fan impeller is made using specially developed high-performance composite material and combines unique material properties with bionic insights.

The high-performance composite material makes it possible to create the innovative shape of the new Cpro centrifugal fan.  The exceptional quality achieved is the result of a one-shot injection moulding process, so it does not have any welded seams or critical connections.  The new shape produces higher efficiency, enabling performance which saves up to 15% energy during operation.

With its specifically profiled three-dimensional blade geometry, the Cpro impeller produces up to 5dB less tonal noise in use (3dB = physical halving).  This reduction in noise makes living and working in the surroundings more pleasant.  Furthermore, less acoustic insulating material is needed – this protects the environment and saves money at the same time.

The composite material combines the positive properties of both steel and composite material:
  • Weight reduction of more than 50% as compared with a steel impeller – this reduces motor bearing loads, guaranteeing longer system lifetimes.
  • The impeller geometry allows tip speeds of up to 70 m/s (60 m/s are customary in the market) – which is only otherwise possible with a steel impeller.
  • No weld seams
  • Can be combined with various types of motors
  • Tonal noise reduction of up to 5dB
  • Suitable for operational temperatures from -20⁰C to +80⁰C comparable with steel impellers
  • Corrosion free
  • No toxic gas emissions
  • Colour stable

The reduced energy usage during manufacture is followed by up to 15% energy which is saved during use.  Moreover, the material can be crushed after the end of the life of the impeller and is 100% recyclable, so there is no waste whatsoever.

The innovative technologies even now exceed the EU minimum efficiency threshold regulations which will come into effect in 2015.

Extremely light, stable, durable, quiet and efficient

Sorption Wheel

067-EcoAirBox-IMG_7398The storage mass in this case has a surface that transmits moisture by pure sorption (ie. without condensation).  The moisture recovery rate is therefore virtually independent of the condensation potential.  The low decrease can be explained with the simultaneous reduction of the temperature difference.

Sorption wheels are recommended particularly systems with mechanical cooling.  The high moisture recovery efficiency, even under summer conditions, dries the fresh air.  This requires less cooling capacity and reduces energy costs for cooling up to 50%.

Series S: sorption wheel, consisting of an aluminium substrate foil coated with a sorption substance (eg. silica gel) for moisture transmission.  This transmits moisture in the form of a gas without condensation.

The depth of the wheel is 200mm.  The wheel is stabilised by double spokes, screwed (and welded) to the hub and welded to the wheel mantle.  This guarantees a long service life.

For stability and performance large-diameter wheels must be made in a segmented design. The diameter of the wheel can be freely selected in 10-mm steps.  The outside of the wheel is held together by an aluminium jacket plate (welded). This guarantees uninterrupted radial runout and enables maximum usage of the wheel surface.

Hub with inner bearing. The hub, whose size depends on the wheel diameter, is fixed to the axle with two internal ball bearings. It is fastened to the crossbars of the casing. This design has the following advantages:
  • The internal bearings are protected against contamination and require little space.
  • The axial lock with circlips makes installation and removal quick and simple.
  • Both bearings are integrated into the hub, i.e. in the same component. This ensures that they mesh together perfectly (in contrast to external bearings). This does not reduce the service life of the bearings.
  • The position of the axle, hub and wheel is precisely fixed by the fastening of the internal ball bearings by the hub and the circlips.
  • The fixed axle connects the two crossbars of the casing. This greatly increases its stability.
