Actually two Bio Diesel processors. Each one can make about a 40 gallon batch, when done you will have slightly less than 40 gallons. I have used these for several years and I can teach someone how to get started making bio diesel. This diesel engines do not require any modifications to the engines that run it. Works great in old engines. Not sure but may not be the best in some of the newer engines.
You will need a pump or a way to get the used fryer oil into the tanks and a filter to filter the oil before putting in the storage tanks or the engine tanks. Mixes with petroleum diesel. With two processors you can make the biodiesel faster. When I used these they were inside a shed so the wind did not hit them. I think the wind blew the one over but it looks okay. It is slower and a little harder to make bio diesel when cold. If you have a heated place you can make about 40 gals about every 3 or 4 days and all summer when above 70 degrees with just one processor. Phone calls or text are the only way to contact me.
