Products Renewables RA (Discontinued)




Model RA is a used-oil-fired heater. It is fueled by "waste" oils.

What is a "waste" oil?

Typical examples are lubrication products found in the maintenance and service facilities for automobiles, trucks, heavy equipment, fleets, etc. These could consist of any combination of engine oil, transmission fluids, hydraulic oils, and even gear lubes and other acceptable lubricants that have been used.

Any firm generating acceptable quantities of waste oil, and having a need for facility heating or process hot water, is a candidate for waste oil heating. This could include everything from large fleet shops, automobile, truck and heavy equipment dealers and service centers, fast lubes, greenhouses, agricultural facilities, and even small garages.

The Federal EPA has designated typical waste oil as acceptable fuel, to be utilized as such in onsite recycling. A heater, furnace or boiler size limit of 500,000 BTU maximum input is required. Other than that, the facility is to recycle the waste oils generated onsite or dropped off at the site by those who change their own oils, and the combustion gases must be exhausted to the outside. States, counties or municipalities may have their own requirements, but usually follow Federal guidelines. In some instances, a permit to operate a waste oil heater, furnace or boiler may be necessary.
