Innovative technology, easy to install and rapid maintenance - these are the reasons for the success of our CRL compact ventilation unit. The previous model of our popular ventilation unit could handle flow rates of 1,300 to 9,000 m3/h. It’s now available in four other sizes up to 20,000 m³/h.

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).
• Four sizes: 11,000 m3/h, 13,500 m3/h, 16,500 m3/h and 19,500 m3/h
• Available as an indoor unit (CRL-iH evo max) and outdoor unit (CRL-A evo max), each with horizontal duct connections.
• The outdoor units are designed to protect the appliance and for ideal operation with intake and exhaust hoods (including droplet separators) as well as a 3D drip tray.
• Variety of extension options, such various heating and cooling coils, filter pre-dryers, silencer modules and filter modules.
• Equipped as standard with space-saving short bag filters.
• Optionally available: second filter stage and carbon filter against odours in the supply air.
• Perfectly integrated into the WOLF control environment: The CRL range can be easily connected to the Link pro interface module via ModBus. In this way, the system can be conveniently checked online in the Smartset portal and the parameters adjusted.
• Heating – ventilation – cooling in one package: “WOLF Clima Split Systems” are optionally available and optimally harmonised with the WOLF CRL.
As standard:
• Eurovent- and RLT-certified
• Compliant with VDI 6022
Top housing values in accordance with DIN EN 1886:
• Thermal insulation: T2
• Thermal bridge factor: TB2
• Mechanical stability: D1
