36" propeller type fan blade, direct drive motor 5hp.
I have a small cooling tower with 2 fans. This time of the year 1 fan runs pretty constantly and the other cycles on and off pretty steadily.
While fan #1 runs it makes fan #2 spin backwards. When fan #2 starts it spins in the correct direction.
Question: How big of an issue is this?
These cooling towers are about 2 years old now, was there some sort of divider supposed to be installed at the factory? Upon original start up of these towers we found out that the factory supposedly installed the wrong type of drift eliminators. It was blowing water over the motors and vibration cut out switches. The factory corrected the problem.
