Tips For Purchasing High Quality Closed Cooling Towers

8 Tips for Purchasing High Quality Closed Cooling Towers

1. The cooling tower shell needs to reach a certain thickness, with high hardness and toughness, good bending strength and good surface gloss. In order to save costs, some cooling tower manufacturers not only choose materials of poor quality, but also the shell is easy to age, crack, and fade, and the thickness and strength of the shell are not good, which greatly shortens the service life of the cooling tower.
2. The metal frame should be high-quality steel with good bearing capacity and strong corrosion resistance. Therefore, the cooling tower should use high-quality steel of national standard. In addition to stainless steel, it also includes some high-quality steel that is hot-dip galvanized. The galvanized layer is required to be uniform and fine, but the steel used by some cooling tower manufacturers is of poor quality (thin). And the galvanizing treatment is not in place, which makes the shell of the cooling tower easy to be damaged by rust.

 3. The Closed Circuit Cooling Tower packing should be made of high-quality PVC and other materials with strong anti-ultraviolet and chemical corrosion resistance.

4. The motor has high insulation grade, good starting performance and reliable operation. As for the direct-connected cooling tower not equipped with a gearbox, the motor used should be a motor with a higher number of series, which has a lower speed and smooth operation.

5. The requirements for the fan are: reasonable structure, small wind resistance, large air volume, low noise, light weight and high efficiency.
6. The cooling capacity is satisfied. The product practice standards of some cooling tower manufacturers do not match the specifications, and the actual volume of the cooling tower is obviously too small, which is a typical cut corners. It is also difficult to achieve a good cooling effect, and the fan speed is too fast, which will not only shorten the service life of the fan and the motor, but also easily cause serious floating water problems.
7. When selecting the cooling tower, the flow rate should be judged according to the actual needs of the equipment. If it is too small, it will not achieve the expected cooling effect. If it is too large, it will cause unnecessary power waste. Regarding the square cooling tower, in the case of large weight, considering the stability of work and energy saving, it is advisable to use the multi-fan parallel type.

8. The overall placement of the cooling tower is scientific and reasonable. On the premise of ensuring heat dissipation (cooling), the shape should be circulated, the gloss should be good, the color will not fade, and it should be easy to repair.
