What Our Customers Say About Us

"I like the water with this holding area system. We don't have water anywhere else in our barn, so the holding area is where we are able to cool our cows. The cows seem to like coming into the holding pen since we put this system in. It has been a reliable system that works year round with the variable speed fans."
Jay Stauffacher
Highway Dairy | Darlington, WI
“At first we were struck by the cost but as soon as we saw what it was capable of, we decided to give it a try. We started with one barn and saw such a big impact that a month later did the other. We feel like the cost has been easily recouped in just over a year.”
