Marley cooling towers, especially wooden decks, what are acceptable overall vibration levels?

It depends on many things. How many cells? How large diameter fans? What speeds? Vertical or horizontal? Draw thru? Center of gravity?

Not counting all of the structural questions.

Can you be more specific?

Could it help ?
If you want it more clear, I could email it if you give me your address.
2 years ago, I contacted Marley for the same question and they never reply.

Thanks,

J Marc I would like a copy of the chart also. Thanks

Can you also supply the source for this material?

I don't have the original document. It come from CTI and could probably be find at http://www.cti.org/

More precisely it is in "Chapter 10, Mechanical Components for Cooling Towers"
and the link is http://www.cti.org/pub/ctimanual.shtml

guys,

im also gonna be involve in cooling towers, what could be the most critical parameters to be observed during commissioning of CT Fan gearbox and Motor Vibration.?
tnx.
