Mechanical ventilation system

Energy savings through demand-controlled ventilation

For several years now, SYSTEM C+® by RENSON® has been a very successful ventilation system thanks to its simplicity, ease of maintenance and energy efficiency.
Now however, we have the new Healthbox® II which includes new innovative technology. SmartZone technology ensures that the house is optimally ventilated, according to the resident’s activities. The new TouchDisplay allows the residents to control their own personalised ventilation program whilst measuring and displaying indoor air quality. This ventilation system can help homes reduce their energy consumption whilst creating a healthy indoor environment.

Read on to find out how the new Healthbox® II makes energy saving and a healthy indoor environment possible!

Thanks to SmartZone technology you can have ventilation controlled within the rooms that you are most present.
