AJL15-FH31A AOLAN Indirect Evaporative air cooler(new technology)

Energy saving green evaporative cooler

Characteristics
1.The casing is made of high strength weather ability polymers which is UV-proof,anti-aging,and resistant to deformation
2.Using specially designed axial fan,with large airflow,low noise,low energy consumption  and wide applicability
3.Using high quality aluminum housing motor,with good heat dissipation,high protection grade,waterproof and moisture-proof
4.Using automatic control of water system and opean type water distributor, so water can flow smoothly and distributor is not easy to block
5.Using highly efficient cooling pads with large evaporation capacity,good cooling efficiency and easy to clean.

Working Principle
Fresh air is divided into many small flows which pass the dry channels in the cooling core.Every small flow is cooled by all the small flows before it crossing pass in another side channels called wet channels. Dry and wet channels are placed one by one with thinner wall separately made of special materials.Heat transfers but no water exchanges.Flows are coolde down but no moisture added.Then every flow goes into wet channels placed its two sides by through its controlling holes,contact with the counter-flow water.It is cooled and little moisture added.Bring the heat out passed from its two-side.Its temperature is lowed down continuously,at the end;its temperature goes under the wet-bulb of its beginning flow,near the dew-point temperature.cif
