B500M Waste Oil Boiler

Ten Year Warranty

The B500M waste oil boiler produces 750,000 net BTU/hr, making it the ultimate answer to your used oil disposal challenges. It is a modified version of our popular B500 with an upgraded induction fan assembly. This modification allows the boiler to increase the amount of air pulled into the combustion chamber. The excess air enables the boiler to have a larger fire, creating more BTU/hr.

The B500M showcases the potential of all the B-Series waste oil boilers.

We can build a custom machine to meet your unique requirements. Each machine carries a 10-year warranty against defects in materials and workmanship. Dedicated craftsmen build the B500M waste oil boiler in Harrisonville, PA, USA.

Engineered for incredible efficiency, our B500M Waste Oil Boilers are the most state-of-the-art design on the market, excelling over competing brands for over 25 years.
