Circular cooling tower: all those cooling towers mentioned in this instruction are energy saving type. Low-noise type and lower-noise type cooling tower, with temperature drop in 3-8℃, are suited to the cooling of ordinary temperature drop like air conditioning refrigeration.Industrial type cooling tower,with medium temperature(＞42℃）& high temperature(＜60℃）and the cooling water temperature drop 10-25℃, enhances the diameter of the tower body, air volume, wind pressure, power and filler height,which makes it suitable for the cooling of high temperature industrial water. This product is suitable for the water temperature under 60℃，

Please inform us while making an order for above 60℃.
