~Evaporative cooling pad Features:
1) Corrugated paper with the spatial crossing linking technology, high absorbability, high water resistant, anti-mildew and long service life.
2) Large evaporation area, cooling efficiency as high as *0%.
3) The product absorbs water naturally, with fast speed of pervasion and lasting effectiveness. One drop of water can diffuse within 4~5 seconds. The natural absorption height is *0~*0mm/5minutes, as **0mm/1.5 hours, having reached international standard.
4) The product does not contain phenol and other chemicals which is irritant to the skin. It is safe, energy saving, environmental protective, economic and durable.
5)  optional.

Working Principle
When the water cross the cooling pad, the water become water film on the surface of the pad. The water film exchange heat with the passing air and evaporate into the air. As the principle of evaporative cooling, controlling the temperature and humidity through modifying humidifying volume and the ventilation size.

Reduce Temperature by “Pad-Fan” System~Why “pad-fan” system is necessary?
Generally speaking, the best environment for growth is in the temperature of ****5℃ and in the humidity of ****5%. In hot summer, the temperature in the greenhouse can be ****0℃ higher than external temperature, which harms the growth a lot or even burns the plants.
By long time development, we finally got an efficient, stable and economic way to cool the greenhouse in hot weather—The “Pad-Fan” system.
 
How it works?
This “pad-fan” system reduces the temperature by evaporation. It consists of cooling pad, pump and exhaust fans with high volume. The cooling pad is corrugate shaped, which has great capability to absorb enough moisture. When the external hot air goes through the cooling pad, the evaporation occurs on the pad surface and creates cool and wet air, which finally cools the entire greenhouse.
 
What the result can be?
The higher the outside temperature, the better cooling effect it can be.
For example, if the outside temperature is above *5℃,the inside one can be around *0℃ lower.
If the outside temperature is around *0℃, the inside one can be around 5℃ lower, and so forth.
