Heat recovery ventilation

profi-air®: heat recovery ventilation healthy & efficient

Heat recovery ventilation is far more than just creating a sound room climate. Since healthy ventilation of a building ensures stable value of the entire property: heat recovery ventilation maintains the structural fabric and therefore the resale value of the building by preventing humidity-related damage and mould growth.

At the same time, heat recovery ventilation reduces heating requirements since less energy escapes through manual airing. Filtered air adjusted to a pleasant temperature ensures a healthy and comfortable climate in all rooms.

profi-air® pipe system for heat recovery ventilation

profi-air is our complete system for heat recovery ventilation and it is suited for all installation situations in both new and existing buildings.

In addition, antistatic and antibacterial agents make the products absolutely sterile.
