The new H-Wave rotor has the potential for the highest heat and humidity transfer efficiency. The newly developed waveform is a major factor in optimizing temperature efficiency due to the warm core of the airflow approaching the duct wall.

Our patented technology is now ready to meet the ever-increasing legislative requirements for ecodesign, and with 100% certainty it is a step in the right direction in the benefits of savings for the future.

Main benefits

  • Maximum possible efficiency of heat and humidity transfer
  • Timeless fulfillment of ecodesign requirements for ventilation units
  • Significant savings for the future
  • Optimal wavelength for the most efficient energy transfer with regard to the pressure loss of the duct
  • Increased perpendicular strength of individual layers and thus the rigidity of the entire rotor
  • The most suitable shape of the duct and the most optimal thickness of the Al foil
  • Optimization of energy transfer and rotor statics


Technical parameters

  • For all types of rotors – temperature, entalpic, sorption
  • Increase in temperature efficiency compared to standard wave by up to 5%
  • Temperature efficiencies of almost 90% for the condensing rotor type
  • Humidity efficiency for hydroscopic rotor design up to 95%
  • Complies with Directive 2009/125/EC of the European Parliament and of the Council establishing a framework for the setting of ecodesign requirements for energy related products and its implementing Commission Regulation (EU) No 1253/2014 (Ecodesign requirements for ventilation units)
