As a food grade facility, Exal Corporation must adhere to strict environmental requirements in their factory. The building needs to keep a constant positive pressure to keep dirt and debris from entering the plant and they need to stay within a specific temperature range throughout the year.

Moffitt created a CFD model that determined CoolStream units would meet both of these criteria. The natural water-cooled air lowers the building temperature up to 15˚ below ambient. It also helps maintain constant positive pressure by running the fan even when the evaporative cooling unit is not required.

To compensate for the cold weather, three (3) 60,000 CFM, 6.5 MM BTU/h Make-up Air Units were also installed. These units were designed to keep a minimal temperature of 40˚ during shutdown and a minimum temperature of 60˚ during operation.

This new ventilation system gives Exal complete control over building pressure, air-flow, and temperature throughout the year.
