1. Cooling tower design working condition of the cooling tower: water inlet temperature t1=37℃; water outlet temperature t2=32℃；wet bulb temperature t=28℃；dry bulb temperature 31.5℃；atmospheric pressure=9.94X104pa.

2. The cooling towers standards for  open cooling tower  (natural draught cooling towers )of Wuxi Ark company is designed according to the national working condition. We can also provide special design for non-standard working condition to customers.

3. Due to site limitation or modeling requirement, the company especially design and custom to make the cross flow cooling tower according required dimensions.

4. Base bearing surfaces are in a same horizontal plane and its elevation and each dimension error is less than 5mm.

5. Base height of the cooling tower h2 should be determined according to the pipe diameter of the water outlet pipe and installation height.

6. The principle of evaporative cooling of open cooling tower  is direct free cooling .

7. Compare to the most efficient cooling system from marley cooling towers, although different as marley cooling tower specs, but our cooling tower services and cooling tower accessories
