Ventilation systems

  • A focus on comfort

    Even if you’re staying at home, there’s no need to miss out on fresh air. Your new VLR ventilation system will ensure regular ventilation for you. Fully automatically and extremely quietly.

    Convenience is in the air

    Your mechanical ventilation system can be left to ventilate your living space. All you have to do is relax and enjoy fresh, filtered indoor air at a comfortable temperature. Our ventilation systems ensure that you really can breathe easily at home. Your ventilation unit noticeably improves the indoor air and your quality of life, with minimal disruption.

    Draughts, along with the loss of over 50 percent of heating energy, caused by window ventilation is a thing of the past. Our ventilation technology works automatically, quietly, and inconspicuously to ensure the necessary air changes.

    Comfort through ventilation systems

    Decentralised ventilation systems

    Our decentralised ventilation systems with heat recovery ensure clean, fresh air in every room. The single units are mounted by your installer in the external wall, making them ideal for modernisation and new build projects.

    Benefits for your home

    A comfortable atmosphere: the result of good indoor air

    What affects our room climate? First, of course, there is the weather: summer heat, dry cold, humid conditions. Fine dust and pollen can get into your home when you open the windows. And you, too, have an impact. After all, you breathe, cook, clean and shower, exhaling carbon dioxide into the indoor air, creating an abundance of scents and smells, and emitting heat and water vapour. A three-person household emits up to ten litres of water per day in the form of water vapour into the indoor air. And emissions from building materials, furniture and floors can also have a negative impact on your indoor air.

    The logical consequence is that the air must be replaced regularly. If it is not, the oxygen content of the air drops while the amount of CO2 and harmful substances it contains increases. And excessive concentration of carbon dioxide in indoor air has been shown to cause discomfort, as well as to negatively affect cognitive performance. And none of us want that... the solution is a ventilation system that works fully automatically to ensure greater living comfort and a better atmosphere in your home!

    Explained in brief

    How a decentralised ventilation system works

    An air distribution system is not needed for decentralised systems. They are therefore especially suitable for retrofitting in a modernisation project. We offer systems with and without heat recovery: in the case of decentralised systems with heat recovery, your installer puts a single unit in the external wall of each room to be ventilated. This may involve systems with two fans and heat recovery via a countercurrent heat exchanger, for example.

    Moreover, you can use units also known as reversible fans. These are always installed in pairs and run alternately so that no underpressure or overpressure is created in the room. If required, you can operate up to eight ventilation units by means of one control unit and one programming unit. Through regenerative heat transfer, the high quality aluminium heat exchanger is charged with heating energy from the extract air. The EC fan changes direction after 40 seconds and blows fresh air from the outside into the room. As this happens, the previously absorbed heating energy is transferred to the supply air. This reduces heating energy loss by up to 93 percent.
