Perfect ventilation:

your protection against Corona

For managers of schools, offices, cinemas, museums, etc. control of the indoor climate by ventilation is an important weapon in the fight against Corona. However, the indoor climate is subject to numerous variables, which makes control particularly challenging.


We offer you full control

Our system measures the CO2 content, humidity and temperature in every room. We collect data and make it transparent via our dashboard and/or app. In this way, you can see the real situation at a glance, in every room, at any time. Wherever you are.


As soon as you need to ventilate, you will receive a notification via our app. If you want, you can also receive a text message or, we can even call you awake. Do you already have a ventilation system and, would you like to know if it works properly? If so, we can make that clear for you as well.
