I have a 220 3 phase water chiller that I can sell for scrap price. The elctronics do not work but the chilling unit works fine. If you know something about electronics you could probably rig up a new thermostat of your chosing on it. Just something that someone might want for the minnow tank. It in Lewisburg TN. Send me a pm if you would like to see it or come get it out of my shop.
