Whether the inlet is to be embedded in a wall, used as a flange inlet for walls made of sandwich panels or installed in the ceiling, Big Dutchman can offer the best solution for every application. For both high and low outside temperatures, the goal is to create stable and circulating air flow so temperature conditions are the same for all birds in the barn.
