Firelake Model 145 - 3 Pass Unit

Now small shops and garages generating low volumes of used oil can gain the heating advantages of owning a Shenandoah® Waste Oil Heater.
The Model 145 delivers high fuel efficiency at an affordable price. It efficiently burns waste oil, transmission fluid and even regular heating oil.


Firelake’s three-pass heater models are easy to maintain with clean-out panels on both ends of the heat exchanger.
The three-pass heaters are also durable and designed for maximum heat transfer with 100% aluminized steel corrosion resistant alloy fire chamber and heat exchanger.
