Easy solutions for indoor air problems at schools Vallox

Carbon dioxide based control is an excellent means to control ventilation automatically based on the need in premises where the number of occupants varies. The carbon dioxide based control identifies when people enter the premises and enhances the efficiency of ventilation almost steplessly. This way, ventilation is not too efficient when there are only a few people present in the classroom ...
