Airpollutech water evaporative type cooling system is one of the most reliable & efficient by which the atmospheric air gets cool and pumped into the department through GI ducting & grills. Due to negative pressure created by the fan, the atmospheric air enters through a pre-filter into the cooling media (may be spray type or pad type). Where the air gets cool near its wet bulb temperature by adiabatic. Further, the cool air is pumped into the department through GI ducting & a double deflection grill with a volume control damper etc
