Moffitt Air Turnover Unit

Moffitt Air-Turnover unit

Air Turnover Units (ATU) efficiently heats large industrial spaces with a minimal amount of equipment. The system pulls the hot air from the higher elevations back to the floor level where it is the most beneficial. This ensures warm air circulates throughout the building, instead of getting trapped at the ceiling, to improve overall building temperatures and worker comfort. The system is designed to maximize efficiency, provide long-lasting, reliable heating, and minimize noise.
