Please don't SHOUT.

Use the design procedures already in place at the facility.

The transformer mfg has fans made to match the transformer. one set of fans will increase the capacity to your requirements. It is about 6 or 8 fans. Call mfg for the correct requirements. no need to calculate anything. it has already been done.

When PWSlack asked you not to shout, he meant please don't type in all capital letters. It is equivalent to SHOUTING in text messaging, and is viewed as extremely impolite if not outright rude. Please be considerate of our forum participants.

As for transformer cooling fans, one manufacturer with which I am very familiar is Krenz & Company. They make a variety fo fans that are used by many of the major transformer manufacturers as well as aftermarket installers:
