RAB Reznor Waste Oil Boilers

These Reznor boilers are equipped with burners that are designed to burn used oil but will also burn no. 2 fuel oil. The used oil must be no heavier than 50 weight and not lighter than no. 2 fuel oil.

Model RAB used oil boilers include the same style burner, oil preheater, and positive displacement pump as other Reznor waste oil products. The air atomizing burner mounted on the boiler door provides excellent flame retention. Air for atomization of the oil is provided by a piston-type compressor mounted on a shelf on the side of the boiler. The oil preheating system (U.S. patent no. 5,080,579) heats the oil, maintaining it at a temperature required for atomization but preventing nozzle after-drip. The burner has electric spark ignition and an electronic cad-cell flame safety system with manual reset. Size 350 burners are wired for a 115 volt, 60 Hz power supply. A size 500 burner requires a 230 volt, 60 Hz power supply.
