The PT-Series Waste Oil System is a quality-built alternative to larger, more expensive waste oil systems.

Our waste oil boilers are compatible with a variety waste oil burners, and can burn a variety of waste oil fuels, including: crank case oil, gear oil, transmission fluid, hydraulic fluid, fuel oil, and vegetable oil, these boilers offer a one-stop solution for saving on heating costs and solving your waste oil disposal problems.

The disposal of motor oils and petroleum based fluids from commonly used internal combustion engines has traditionally been a burden. The effects of improper disposal can be devastating to the environment. One quart of waste oil can pollute over 250,000 gallons of water and clean up is next to impossible. Waste oil is toxic and carcinogenic and can be a fire hazard if not properly disposed. On-site recycling is the EPA preferred method to dispose of use oils.
