Model CB-5000 Furnace


The Clean Burn CB-5000 is the largest used-oil furnace the EPA allows. No other unit is as robust and reliable for extracting free heat from used oils. The CB-5000, which generates approximately 500,000 BTU/hr, is the choice for large repair and service facilities with multiple bays where larger quantities of used oil are generated and/or collected. A Clean Burn Distributor is the expert you want for furnace selection and installation.
