Ventilation -  Reduce heat stress and resultant production loss by utilizing natural ventilation designs and practices and further optimizes your system with automated ventilation systems. Combine exhaust fans with intake shutters and environmental controls to replenish, cool, and refresh the air inside your dairy barn.  With the right design, your cows will close their eyes and imagine they're on the hillside pasture with a fresh cool breeze caressing their face; happily munching away. 

Air Circulation -  Depending on your location and building design, air circulation may be another vital component of your environmental control system. Mount the circulation fans to rafters, posts, columns, hang them from the ceiling to create a horizontal airflow to mix, temper, and refresh all areas of the building.  Check out the Misting Systems to really cool the air and animals.
