External cooling tower turbine, installed outside of the cooling tower air tube motor position, without any space limitations, external turbine impeller diameter, number and shape, angle can be designed according to the customer's actual situation to enlarge, increasing torque increase conversion efficiency. 

Different flow and pressure of the system design, to achieve the most perfect transmission conversion ratio to achieve cooling tower fan speed is greater than or equal to the original motor-driven fan speed. External turbines snail shape
