The ST rotor is ideal for ventilation systems without mechanical cooling. The condensation rotor only transfers humidity during the winter when extract air condenses in the storage mass and is taken up by the supply air stream. Untreated aluminium foil is used for heat recovery.

Reduces CO2 emissions
Lower investment for heat generation and distribution
Ready-to-install and functional product
Perfectly coordinated system (storage mass, drive, control unit)

The advantages

  • Proven: for many years in numerous applications
  • Efficient: high levels of temperature efficiency
  • Easy to use: excellent indoor climate in the winter
  • Individual: wide range of accessories

Technical information

  • Reliable: Eurovent-certified and hygiene-certified
  • Stable: differential pressure stability up to 1000 Pa
  • Flexible: width can be selected in 1 mm increments
  • Extensive range: shafts in six different heights all achieve optimum efficiency with a low pressure drop
  • Rotatable: suitable for vertical and horizontal installation
  • Safe to operate: complete drive technology available

Casing

The robust design prevents rotor movements that can cause leaks.

Suitable casing is available for each rotor size in the range. It can also be custom-made for the room ventilation unit in question on request. The standard casing is intended for vertical installation. However, smaller models can also be made for horizontal installation.

Storage mass

The ST storage mass is a cost-efficient solution for recovering sensible energy (temperature). The rotor only transmits humidity when the extract air falls below the dew point. Epoxy-coated foil should be used for applications with a major risk of corrosion, such as in industrial ventilation. Seawater-resistant foil is available for marine applications (e.g. for use in cruise liners and coastal environments).

Drive

Hoval Enventus provides easy, reliable drive equipment for both constant and variable speed operation.
