Central mechanical ventilation

CWL-T-300 Excellent

The WOLF CWL-T-300 Excellent central ventilation system has an especially slimline design. It can either be used alone or in perfect harmony with your heating system when integrated into your building services centre.

Perfectly coordinated with your HVAC system

The CWL-T-300 Excellent mechanical ventilation unit has been specially developed for use in combination with a heat pump in a compact building services centre. It can also be combined with a gas or oil condensing boiler instead of a heat pump. When integrated into a building services centre, the unit interacts seamlessly with all HVAC components.

Naturally, you can also use the CWL-T-300 Excellent as a standalone system. The advantage: the elegant, tower-shaped solution has a sleek and space-saving design that fits perfectly in any installation site and can even be free-standing.

Automatic adjustment

The CWL-T-300 Excellent controlled mechanical ventilation unit is equipped with sensors for CO2, humidity and air quality (VOC content) so the output is always automatically adapted to suit your current requirements. This also keeps the air quality in your home at pristine levels. Read more

No draughts

Draughts are formed when bodies of air at different temperatures meet. The CWL-T-300 Excellent has a reheater coil that prevents this phenomenon from ever occurring. Read more

Optimum airflow

The appliance adjusts the flow of fresh air and extract air precisely to ensure that air exchange is perfectly balanced. This prevents any areas of low or high pressure from forming.

Fail-safe, quiet as a whisper and user-friendly

Integrated preheater coil

The preheater coil guarantees that the ventilation unit works reliably even at nippy sub-zero temperatures in the depths of winter. You will enjoy fresh air all year round no matter how cold it is outside. Read more

Very quiet EC fans

The noise produced by a ventilation system is largely due to the fans. The CWL-T-300 Excellent uses EC fans that are particularly quiet.

Indicates filter changes

The CWL-T-300 Excellent is also an impressively low-maintenance unit. And when the filter really does need changing, this is simply shown on the easy-to-use display.

Perfectly in tune with you.
