The Air Destratification principle eliminated stagnant air in heated buildings with open spaces by recirculating hot air which becomes trapped at the ceiling. This is accomplished by removing colder layers which maintain the thermal barrier responsible for the problem. Large volume air movement turns the room air over 1 to 5 times each hour. Continuous air circulation then thoroughly mixes the air to maintain uniform room temperature.

This uniform room temperature eliminated the possibility of condensation forming on stored materials because of uneven room temperature. Cold air from open doors in shipping and receiving areas becomes less of a problem with and Air Turnover unit. Temperature recovery is almost instantaneous after doors are closed.
