Ventilation

Good indoor air quality depends on a reliable supply of fresh air and effective removal of stale, humid air. Tersus offers HANSEN ventilation systems designed for local, controlled ventilation in residential and other indoor spaces. The systems combine fresh-air supply with heat recovery, helping reduce the heat losses associated with ventilation while maintaining a comfortable indoor environment.

HANSEN systems operate through alternating ventilation cycles. During one cycle, indoor air passes through the ceramic heat exchanger before being discharged outside, storing its heat in the exchanger. During the following cycle, fresh outdoor air passes through the same heat exchanger and enters the room with the stored heat recovered. The system can therefore provide fresh air while helping to retain energy within the building.

The range includes different HANSEN ECO models designed for varying room sizes and ventilation requirements. Models such as the Eco Active 100, Eco Active 150, and Eco Wireless 150 offer different airflow capacities, while quiet operation makes them suitable for regular use in living and working spaces. The systems use filters to help ensure that the incoming air is cleaner before it enters the room.

HANSEN ventilation systems can also be connected and controlled as a coordinated group. Depending on the model, wireless communication allows several units to work together, while the HANSEN application provides additional control options. This makes it possible to adapt ventilation to the requirements of the building and the people using it.

Tersus provides advice, installation, maintenance, and servicing for HANSEN systems. With compact local units, ceramic heat recovery, adjustable airflow, and different control options, the range provides a practical solution for introducing fresh air into rooms without requiring a conventional central ventilation installation.
