We have a Cook n beals spin float and heat exchanger. The spin float runs great. Turn it on and go. It is loud and I would like to have a room built around it someday. We took the tray out from the bottom and put a barrel underneath that we cut down to fit to catch the wax. The only time you need to clean it out is if you run into some crystallized honey. We cleaned it out once durning the season this year right towards the end of 27 extractings. The heat exchanger gives me some fits sometimes at startup. Our honey house is unheated and the honey and wax during startup is pretty cold later in the season. Also I did have the power go out but I heard the spinner winding down and flipped the gates on it so saved it from having a big mess. This outfit has probabbly about paid for itself condidering we hardly have any melter honey anymore.
