IFJ: An Air Turnover Product for Smaller Spaces

Any small business building a new structure will encounter certain unavoidable problems during the course of design. Until now, one area of difficulty was always the design of a heating and cooling system that could save on energy costs and maintain a comfortable working environment for employees.
'Air Turnover Systems' is a designation describing a unique class of commercial and industrial heating or heating and cooling equipment used to condition large spaces. The IFJ is an air turnover system designed for smaller spaces (4,000 to 12,100 CFM) and can also provide cooling via an optional "A"-coil with cooling capacities from a nominal 9.5 to 24 tons.
The Air Turnover principle eliminates air stratification in heated buildings with open spaces. It does this 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 eliminates 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 an Air Turnover unit. Termperature recovery is almost instantaneous after doors are closed.
