De-On Supply
lean Burn multi-oil heating systems let you safely and economically burn used oil generated on site. It provides free heat — dramatically cutting or eliminating your heating costs — while eliminating your used oil liability and disposal costs.
Clean Burn products are ULC-listed, meet all Canadian regulatory safety requirements, feature advanced combustion technology and carry a 10-year limited warranty.
Not all used-oil-fired furnaces are built alike. In fact, many so-called used-oil furnaces are merely adaptations of conventional fuel-oil heating systems. Not so with Clean Burn. Every Clean Burn furnace is designed exclusively to burn used oil–and burn it efficiently, safely, and reliably. From the design of the burner and heat exchanger to the distributor who installs and services it, a Clean Burn furnace is your best choice in used-oil heating and recycling. Here’s why over 80,000 owners chose Clean Burn.
The Clean Burn CB-200-CTB, CB-350-CTB and CB-500-CTB Coil Tube Boilers are engineered from the ground up exclusively to burn used oils and standard fuel oil for added versatility. Clean Burn boilers provide hot water while complying with CSA regulations for used oil recycling through heat recovery and have the required Canadian Registration Numbers (CRN) numbers for each province.
The Clean Burn coil tube boiler design is unique in the industry because of its ease of access for maintenance and service. It is designed and engineered for use as a single boiler unit or as part of a series of boilers working as a larger system. They are listed at 200,000 BTU/hr, 350,000 BTU/hr, and 500,000 BTU/hr respectively and are unsurpassed for robust engineering, construction and reliability.
Typical installations include car washes, truck service facilities, radiant floor heating, and other places where economical production of hot water is an operational benefit.
The DSi Tank Mounted Furnace Systems are designed for those shops with minimal storage requirements. The tank provides a solid workbench area in addition to a practical storage area for used oil. The mounting brackets make for a simple set up of your Clean Burn furnace. It is ideal for applications where hanging of a furnace is impractical and space below the furnace is available. This design also provides easy access for routine maintenance and service. DSI can tank-mount a variety of furnace models, tailored to your shops requirements.

Energy Savings
Selecting the low combustion stage setting will reduce fuel consumption. This can save on operating costs when heat demand is lower.

Fuel Preheater
Excellence Reborn
As ambient temperature decreases, viscosity increases, to counterbalance this effect, a heater is built into the fuel line to keep the fuel moving smoothly.
