Short description

Swiss Rotors energy recovery wheels (rotor) are regenerative air-to-air energy recovery parts of the air handling unit. The main function of regenerative air-to-air rotors is the transfer of sensible (temperature) and latent (humidity) energy between exhaust and supply airflows. Regenerative rotors are important for energy conservation in ventilation systems that treat outside air in order to ensure good, clean air in your internal environments

Available in 3 recovery types:

  • Sorption / total

    Both foil layers desiccant coated, high latent recovery efficiency and hygienic quality of the device is ensured by sorption material (3A molecular sieve)

  • Enthalpy / Hygroscopic

    Mixture of media types: one foil is desiccant coated and the other in standard aluminum providing moderate latent heat recovery at a cost-conscious price.

  • Condensation / non-hygroscopic

    No desiccant to recover moisture from exhaust air (sensible heat recovery only)

Product Data / Advantages

  • Monolith wheels made using patented foil forming technology that mechanically interlocks foil layers together without any segments, welded spokes or profiles to ensure unconstrained airflow
  • Double peripheral sealing system ensures no bypass and thus creates around 2% higher energy recovery whilst maintaining very low leakage (EATR)
  • Integrated intelligent control and regulation system
  • Silent and highly effective EC or AC motors fully self-contained within rotor casing
  • Efficient and highly automated manufacturing process
  • Direct replacement of the most common industry standard sizes
  • Both the SF and RT series are available with a 3A molecular sieve coated, monolith aluminum wheel
  • No need to keep wheels on stock (with just 2 weeks lead-time)
  • Best price on the market

    • How it works

      In energy recovery wheels (rotors), exhaust air and supply air pass the wheel matrix in a opposite direction. The energy from exhaust air is then transferred to the supply air through the wheel matrix. Thanks to the alternating airflow direction, the wheel is self-cleaning and frost resistant at low temperatures.
