MAIN FEATURES
In working environments heated with hot air systems the need to keep the
temperature at approximately 18°C, causes the air to stratify at the top of the
room, with much of the heat remaining unused, which is destined to flow
toward the atmosphere.
The DST destratifier eliminates this problem by generating a vertical flow of
air to reduce the difference between the temperature at the floor and the
temperature at the ceiling to about 3°C.
In the hot season the DST destratifier may be used to obtain a good
ventilation.
