FN series of square counter-flow glass cooling tower is the fourth Ministry of Machinery Industry Design Design Institute of energy-saving new products. The product uses the patented "energy-saving fiberglass cooling tower" obtained by the four factories. In particular, the cooling tower fan is equipped with a variable torque off-pole two-speed motor. When the temperature is low (such as at night), the motor drives low speed and the cooling tower noise 3-5dB lower (A). In addition, the use of two-speed motor energy-saving significant, after calculation, more than one cooling tower with a single-speed motor, although the wet air humidity in the air can be stopped when part of the motor power, but still more than double-speed motor with more power 40% Year).
This product is also applied to the four won the national patent "square counterflow cooling tower with trapezoidal wave packing material" by the Beijing Institute of Watermelon and Foshan solid tower test, the thermal resistance characteristics are better than other fillers.

Product performance and choice
1, design parameters:
Industrial tower: air wet bulb temperature τ = 28 ℃, cooling tower temperature drop: 10 ~ 25 ℃.
Civil tower: air wet bulb temperature τ = 28 ℃, cooling tower temperature drop: 5 ~ 8 ℃.
2, select the tower need to know the cooling water Q, into the tower water temperature t1, the tower water temperature t2, wet air balloon temperature τ.
3, the cooling tower material resistant to -50 ℃ low temperature, but the coldest month average temperature below -10 ℃ should be specified in the order, in order to take anti-icing measures.
4, the turbidity of circulating water is not more than 50 mg / L, short-term not more than 100 mg / L. Should not contain oil and mechanical impurities. Necessary to take algae and water quality stability measures.
5, cooling tower inlet and outlet pipes can be 90 °, 180 °, 270 ° rotation.
6, Cloth water system is designed according to the nominal water flow, such as the difference between the actual amount of water and the nominal water within ± 15%, when ordering should be explained in order to modify some of the data.
7, cooling tower inlet temperature does not exceed 60 ℃, such as more than 60 ℃ should be specified when ordering.
8, adjustable fan blade installation angle, but to maintain the same angle. and the motor current does not exceed the rated current of the motor.
19, fans can be short-term low-speed reversing to eliminate ice.
10, when using the cooling tower tray to do when the pool must be installed separately "automatic water supply pipe", "rapid water supply pipe", "sewage pipe", "overflow pipe", when ordering must be made, the cost of extra.
11, motors, fans are supporting the supply, the factory sent staff to the scene to install or technical guidance.
