Programming tunnel mode
In a barn set up for tunnel ventilation, air inlets are located on one end wall of the building, while
exhaust fans are on the opposite end. When tunnel ventilation is active, air moves through the
length of the barn at a higher speed than it does using traditional cross-flow ventilation. This creates
a wind chill effect that maximizes the cooling of animals in hot weather.
The benefits of using tunnel mode are reduced heat stress, increased animal comfort, and the ability
to maintain productivity during hot weather.
Producers often use tunnel ventilation alongside traditional cross-flow ventilation. During cool
weather, they use sidewall fans and ceiling inlets. During hot weather, when more cooling is
required, they switch to tunnel ventilation.
Select ventilation gives you a way to switch off or close equipment not needed during tunnel mode.
Tunnel mode allows you to automatically switch from cross-flow to tunnel ventilation. During the
transition, tunnel fans switch on and inlets open, while sidewall fans switch off and ceiling inlets
close.
