1, Why choose evaporative cooler? 
1. Fully automatic electronic screen display controller, easy operation; 
2. Using the company's unique design of 4 leaf aluminum alloy fan blade, which is aluminum alloy die casting, and powerful airflow, the effective air distance is up to 35 meters. 
3. Automatic water supply system, the open water distributor and the distribution is uniform and smooth 
4. The shell is made of weathering injection molding, high strength, corrosion protection, anti-aging, anti-ultraviolet, beautiful, durable and stable performance; 
5. High-performance evaporator (cooling pad), well evaporation and good cooling effect, and process with high-tech, completely eco-friendly; 
6. High quality cast iron motor with strong power. 

Evaporative vs Refrigerative 
Evaporative can offer you general health, fresh air, energy saving, lost cost and ECO friendly. 

2, Characteristics 
A. Our evaporative air cooler The casing is made of high strength weather ability polymers which is UV-proof, anti-aging, and resistant to deformation. 
B. Different air discharge type(including top, down and side)can meet different installation requirements of various applications. 
C. Using specially designed axial fan, with large airflow, low noise, low energy consumption and wide applicability. 
D. Using high quality aluminum housing motor, with good heat dissipation, high protection grade, waterproof and moisture-proof. 
E. Using automatic control of water system and opean type water distributor, so water can flow smoothly and distributor is not easy to block. 
F. Using highly efficient cooling pads with large evaporation capacity, good cooling efficiency and easy cleaning. 

3. How many degree can take the green house down? 

That depends on the temperature and humidity of the ambient air. Referring below specific ambient conditions.
