Climate controller for automatic ventilation of classrooms and offices
Climate controller for automatic ventilation of classrooms and offices
Controlled ventilation of classrooms and offices with the STUHL SCC-C02
Virus reduction and CO2 reduction in one
The use of the SCC-CO2 in combination with a ventilation system is an indispensable tool

to automated ventilation systems.
Many parents, teachers, building services managers and business owners have high hopes for mobile air purifiers to reduce the risk of contagion. However, their benefit compared to automatic ventilation is controversial.A first comprehensive study is available:
Ventilation techniques in comparison
Significantly improved air quality with
automatic ventilation systems
The installation possibilities of ventilation systems for classrooms or
office rooms are complex
Sluggish employees and sleepy students –
CO2 concentration often above guideline value
The level of carbon dioxide is an indicator of indoor air quality
Often, ventilation in offices and classrooms is inadequate. Good results are usually achieved only by decentralized ventilation systems.
Where they were in use, the
average CO2 concentration
almost always!
