TUBE-VENT is a unique ventilation system consisting of a specially selected fan, which is connected to a suitable ventilation duct. Each individual ventilation system is customized according to the amount of air required by each barn and the category of animals. The amount and speed of air movement varies with the help of automated operation depending on the air temperature in the barn. This ensures better conditions for animals, reduces the negative effects of heat stress and provides fresh air throughout the year.
