Howdy everyone,

I am searching for mechanical information about large cooling tower fans.

I have found reference to fans up to 10 feet in diameter. Is this the upper limit or do they go even larger?

What is the fan motor horsepower rating and load on the largest towers?

Which fan manufacturers have the best reputation for high quality?

Any links to performance curves and sound decibel measurement greatly appreciated.

Thanks in advance for sharing your knowledge.
