Chiller Tonnage

[jthjr]

Can someone tell me the tonnage for the following three chillers from their model numbers?

York YTG1A1B2-CGH8
York YCWJ55HE0-46PA
York YCWZ33AB0-46PB

Is this information avaiabe in either Preston's Guide or Technical Reference Guide by Carson Dunlop?

Or is there a different refence guide for commerical HVAC equipment that has this type of info?

Thanks.

Why not ask the manufacturer?

Or even do a websearch:

I have done both in the past.

I guess I was trying to see if someone would give the tonnage answers and then mention they got them out of a book. And then tell me you can get the book at...

Thanks for your reply.

The second and third chiller has a nominal tonnage of 55 and 33 tons, respectively. (use the 5th and 6th digits)

I got this from the technical guide book, you can get that from the manufacturer. (or website)

knowledge is power

@cdxx139 - These numbers refer to the size of each of the recip compressors. ie. two #5's. This is in the posted manual which I also found but doesn't tell much more. It gives the compressor part numbers, but not the nom. tons of each. The OP would need to take the comp part numbers to the manufacturer, in which case may as well just send the chiller number.
