DeltaStream adiabatic natural cooling unit

The DeltaStream is a tri-purpose device that provides adiabatic cooling, heating, and air re-circulation for your building. It is designed for commercial and industrial applications to cool outdoor supply air 10° to 30°F below ambient. Utilizing evaporative natural cooling it can make a dramatic difference in hot facilities. It is up to seven times more efficient than conventional air conditioning and in many cases just as effective. Moves up to 17,500 CFM.

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.
