Generator radiator ATS redundancy

[Jonmad99]

Has any one ever seen any kind of redundancy built into an ATS? I ask because the geniuses that I work for decided that they didn't want to see the ugly radiators on the side of the building. Instead they put them on the roof, which in turn, now makes them require power to turn the fans. If their ATS ever drops out we are dead in the water. Any ideas or has anyone seen any redundancy that could work in this situation?

Why would the radiator fans be on their own ATS?

I would have expected the to be fed directly from the genset.

Do you have a second generator to make an ATS worthwhile?

If so, you can use a isobypass type ATS

Not sure what you question is but from what you state it sounds like the radiators for the backup generators have been separated and placed on the roof and the cooling fans are powered by motors (which are normally powered by the gen) that are fed from an ATS. With that said are you asking how to provide a backup source of power to the fan motors should the ATS fail to transfer? :?

Anytime we have powered fans or damper motors for generator cooling it has been a direct tap of the generator output.

If the generator runs the power goes to the fans or dampers regardless of the transfer switch position.

This also allows the generator to exercise or be started without the transfer switch changing state.
