SYSTEM FOR ELIMINATION OF WET FOG

The function of this system, especially requested by the textile sector, is to enter indoor an heated air flow rate with low specific humidity, enough to keep the ambient dew point below the surrounding walls temperature, eliminating fog and smoke, preventing condensation of moisture within the concerned area.
The system consists essentially in an air handling unit comprises a filtering section, a heating coil and a fan; the air through some ducts, will be introduce indoor with a controlled level of heat and humidity, keeping an appropriate increase in temperature, to obtain the elimination of fog in the environment.
The extraction, however, will be performed from the top of the area, where the phenomenon of stratification of humid air happens, through suction hoods, ducts and exhaust fans .

kg of evaporated water/mq per hours, of free surface (at ambient temperature of 21°C) for various water temperatures and for various air speeds.
