[We have a used chiller 4 ton, we got a new 20 tons chiller. This used unit needs a reservoir and a control temperature for the reservoir , it was working great until we shift for the big guy. It is prepare to work outside in winter and summer. I check the other day the abandoned unit and looks like is a little oily around the expansion valve, so maybe there is a small leak that need to be fixed.
You will need a refrigerant guy to install it, it is a 3 phase chiller.
we ask for $1500 (good deal) and we help you to put it on your truck. it is in our roof right now
