Combi-Tunnel ventilation

Combi-Tunnel ventilation is a negative-pressure system that is best suited for areas with significant daily or seasonal temperature fluctuations. It ensures optimal conditions for the animals by switching between ventilation principles.

System – summer

During warm periods, fresh air is pulled in through a Tunnel opening to create a chill effect using airspeed through the barn with Tunnel ventilation. Negative pressure is generated by wall fans at the opposite side of the barn.

System – winter

During cold periods, fresh air is pulled in through wall, roof, or ceiling inlets, providing even air distribution to remove excess humidity, CO2, and ammonia. Low air speed is desired to prevent drafts. The air is exhausted through chimneys or some of the wall fans.
