Aerotech Dairy Tunnel Cross Ventilation Dairy Tunnel or Cross Ventilation Maximize production levels with Aerotech fans and cooling systems If you experience a decrease in milk production during hot weather, Aerotech tunnel or cross ventilation system is your answer. Aerotech systems can keep production levels consistent throughout all seasons. Tunnel or CrossVentilation: the exhaust fans draw outside air in through a evaporative cooling system or inlets. The combination of air speed and temperature drop keep livestock in a comfortable and productive environment. FEATURES Fan Features: Vortex® and Advantage® Fans Highest Performance, efficiency and reliability High airflow (CFM) reduces total fan requirements. Impressive CFM/Watt reducing energy costs. Vortex fans are protected by U.S. Patent No. 6,616,404 and 6,953,320. Express Cool™ System: Evaporative Cooling system allows control over interior building temperatures and assists in further production increases. CS Self Contained systems feature extruded-aluminum headers along with a PVC reservoir which eliminates the need for a large sump tank. CM systems feature exclusive extruded-aluminum header and footer, but requires an in-ground sump tank. Fan Performance Information Cat.
