COMFORT THERMAL WHEEL HEAT EXCHANGER VENTILATION UNIT
CRL-iD/iH for indoor installation

Maximum air quality and tightness despite the short installed length.

The new CRL series from WOLF sets new standards. Three different thermal wheel heat exchangers are available to choose from: Versions with sorption, enthalpy or condensation rotors.
All versions are equipped as standard with the new sealing system that features an extremely high tightness rate of 98 %. The sorption rotors (option) enable direct moisture transfer from the extract to the supply air side. All appliances are fully assembled electrically and, thanks to their modular design, very easily installed.

CRL compact units with heat recovery provide rooms with fresh, filtered outdoor air, in sufficient, variably adjustable amounts. At the same time, a corresponding volume of stale indoor air containing CO₂ is removed and expelled as exhaust air. In this way, other pollutants such as odours, fine dust, moisture, etc. are removed effectively as well. Heat is recovered using a corrosion-resistant thermal wheel heat exchanger with heat recovery rates of up to 90 % and moisture recovery rates of over 90 %. This significantly reduces the primary energy costs of the heating system. The high energy efficiency also explains the favourable SFP value (specific fan power).

COMFORT THERMAL WHEEL HEAT EXCHANGER VENTILATION UNIT CRL-iD/iH

iD for indoor installation with vertical/horizontal duct connection and iH for indoor installation with horizontal duct connection
  • Output sizes: CRL-iD/iH -1300, -2500, -3500, -4800, -6200, -9000 (m³/h, nominal air flow rate).
  • iD for indoor installation with vertical/horizontal duct connection
  • iH for indoor installation with horizontal duct connection
  • Combined supply and extract air unit with integral, high performance, thermal wheel heat exchanger for heat recovery, with the characteristic benefits (no condensate removal necessary, resistant to icing-up).
  • Highly efficient, variable speed EC fans ensure an optimum air change rate.
  • Depending on customer requirements, 3 different rotor types are available: Sorption rotor (recommended by WOLF – with the additional benefit of moisture recovery in winter and pre-cooling in summer), enthalpy rotor, condensation rotor
  • Compact 3-piece casing design (iD, iH) with integral, fully wired control unit; can be optimally split for ease of handling and the programming unit can be used as a remote control.
  • Thermal wheel heat exchanger types featuring the new, all-round, WOLF labyrinth sealing system, i.e. a completely new sealing system with leakage rates below 2 %.
  • Extensive range of accessories.
  • The units comply with all relevant standards and guidelines, such as VDI 6022, VDI 3803 and EN 13779

Compliance with all relevant regulations and standards goes without saying for WOLF. Furthermore, our CRL units are certified to EUROVENT. Thanks to our international experience, projects abroad can also be completed with the aid of our professional consultants.
