INFORMATION FOR PROFESSIONALS
Comfort domestic Ventilation CWL-2

The most compact in its class, extremely quiet and highly efficient – that is the new central domestic ventilation unit series CWL-2 from WOLF. The precise flow rate measurement, enthalpy heat exchanger, preheater and exceptionally easy maintenance make the CWL-2 a true premium product. The new overall concept results in maximum comfort even at low outside temperatures – without draughts or irritating noises.

Nine convincing arguments
for you and your customers

A genuine
powerhouse

State-of-the-art technologies mean outstanding thermal and electrical efficiency. At the same time, the CWL-2 generates unparalleled low noise levels. The complete redesign makes the appliance the most compact in its class, even taking into account the preheater integrated as standard.

Quieter
than ever before

Thanks to the aerodynamic internal configuration and highly-innovative components, the CWL-2 runs extremely quietly, even at high speeds. It is therefore usually possible to avoid the use of external silencers. WOLF ventilation units are ideally suited to the new flow and maintenance-optimised UniAir 125R and 125Q design valves. The integrated helix optimally distributes the supply air throughout the room.

Fan technology
of the latest generation

The latest fan technology ensures an optimally-adjusted flow rate. The precise flow rate measurement with impeller anemometer guarantees smooth running and balanced flow rates. At the same time, this technology creates a clearer structure and a high level of serviceability.

Attractive design

In the modern silver-stripe design, the CWL-2 device series perfectly fits in with the current WOLF look. In combination with the new WOLF UniAir supply and extract air design valves, the CWL-2 brings a sophisticated yet discreet look into the living space.

Enthalpy heat exchanger
for moisture recovery

The CWL-2 series is also available with a moisture-recovering heat exchanger. Thanks to the antibacterial polymer electrolyte membrane (PEM), no odours or pollutants are released into the supply air - for optimum hygiene and comfort. A wastewater connection to the appliance is no longer necessary.

Pre-heater and automatic bypass
as standard

The CWL-2 thinks for you: At low temperatures, the intelligently-controlled preheater ensures trouble-free ventilation. In summer, the customer uses the cool outside air at night via the fully automatic bypass.

Rapid installation
and simple operation

With the new colour touch display, you can now operate the appliance even more easily. The digital step-by-step instructions guide you through installation and filter changes quickly and intuitively. The ball siphon guarantees maintenance-free condensate management and fault-free installation.

Directly
online

With the WOLF Link home interface module and the Smartset portal, you can monitor your customers' systems via the internet at any time. This makes it easy to read the status of the system and optimise settings without costly travel.

Demand-controlled ventilation
for a comfortable indoor climate

Sensors for CO₂, humidity, and air quality enable on-demand ventilation. Thus, the CWL-2 always ensures the optimum air quality as desired by users.
