The fresh filtered air is made to pass through the cooling coil of 4 Row deep (Sensible cooling) where in the dry bulb temperature as well as wet bulb temperature is reduced. This heat is rejected through cooling tower via pump and piping. This is with 100 % fresh air and is used only during summer.

Multi Layered Air Supply. Uniform Air Distribution. Extruded Aluminum construction. With or Without Volume Control Dampers. 1, 2, 3, or4 Way Discharge of Air.

Evaporative Cooling Pad with exclusive cross fluted configuration is a contact medium specially engineered for direct evaporative cooling and humidification of air. The Cooling Pad is made of corrugated sheets which are assembled in self-supporting pads of light-weight sturdy construction. Evaporative Cooling Pad is manufactured from a special cellulose paper, impregnated with insoluble anti- rot salts, rigidifying saturants and wetting agents.

Fill type system can attain saturation efficiencies of 90% as against 60% efficiency of conventional system. Compact pre-fabricated design to take less space, volume nearly 40% of comparable machine. No masonary work required for room and can be located inside or outside a building. Power consumption nearly 50% of any comparable spray machine due to low pump power and low pressure drop. Maintenance negligible as no nozzles are involved and hence trouble free service. Low noise level in machines as there are no high pressure nozzles. Quick installation as machine is factory fabricated and has flexibility to re-locate at any time.

The core part of Roots Air Systems evaporative air cooler is the high efficiency evaporative cooling pad. Natural multi-layer corrugated cellulose material, which utilizes the physical phenomenon of water evaporation absorbing heat, evaporation area affecting evaporation effectiveness, pump brings water up to water distributor and water goes through cooling pad regularly, which generates a water screen, then the fan runs to make a negative pressure, when outside hot air goes through wet cooling pad and contacts water, water evaporates, and heat is brought away and cool air comes out, dust is taken down by water flow to the bottom at the same time. By this circulation, fresh air without dust always provides you a favorable and more comfortable environment.
