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
oxygen-rich and hygienic air.

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:

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!
