Asheville Refinery manufactures oil refining systems that enable the recycling of waste vegetable and motor oils. Our unique design uses no harsh chemicals and only inert natural materials. The Refining process is a simple gravity fed system that requires no power, or chemicals of any type. Use is as simple as filling the feed module with oil, and allowing gravity to flow the dirty oil through the refinery and come out cleaned. While traveling through the refining module, the oil is naturally dewatered, other water based contaminants such as acids & salts are removed and solid contaminants above 9 Microns in size are trapped in the refinery. All of this is done via a single step without the need for heat, electricity or chemicals, producing only clean usable oil.
