Moffitt CoolStream

The Moffitt CoolStream system is designed for commercial and industrial applications to cool outdoor supply air 10° to 30°F below ambient utilizing evaporative natural cooling. It is up to 7 times more efficient than conventional air conditioning and in many cases just as effective.

The units use direct drive variable speed motors to reduce maintenance while increasing efficiency. Each is constructed of aluminum to reduce weight and eliminate corrosion without compromising durability. Learn more about Hybrid Ventilation in our blog post here.
