IFA (ATC-HC) Series Air Turnover units are unique floor mounted heating and cooling, or cooling-only units designed to maintain comfortable room temperatures without a duct distribution system.

IFA units are available with air delivery from 13,000 to 81,000 CFM. Standard DX cooling coil capacities are from a nominal 27 to 148 tons. Standard chilled-water coil capacities are from a nominal 28 to 140 tons. The optional indirect fired gas heat section had capacities from 650,000 to 4,000,000 BTUH.

The IFA utilizes the Air Turnover principle to take advantage of air stratification in buildings with open spaces. It does this by allowing hot air to become trapped at the ceiling. Large volume air movement is provided by centrifugal fans, which turn the room air over 2.5 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.
