    Balanced ventilation systems

    Increasingly well insulated buildings with increasingly well sealed shells lead to humidity and odours no longer being able to permeate through the joints. Added to this is the fact that fresh air can also not enter the house unhindered. This is where a balanced ventilation system (BVS) comes in: These ventilation-supported systems ensure an air exchange by introducing fresh air into the rooms and transporting used air, pollutants and odours away. This increases well-being and prevents moisture damage and mould:

    Indoor ventilation maintenance – here’s how it’s done

    Indoor climate measuring instruments and probes from Testo support you in all phases of a BVS: From the planning phase through the optimum adjustment up to regular monitoring of the performance – intuitively, precisely and taking legal conformity into consideration. Indoor climate measurement technology from Testo can of course be used not only for centralized, but also for decentralized indoor ventilation.
