This chiller, it looks like it is an aircooled chiller.

How does it compress the refrigerent? It does not make the typical chiller sound I am used to hearing, much quieter.

How old is it, and how many tons? Should I be budgeting for replacement and if so, what is a good option?

It is unusual for me to see a chiller at a small, 8,000 sf building, which unfortunately, is a reheat system, very high utility bills, but I have not figured out any way to convert it to a better system.

Thanks everyone for being so helpful.
