Cantherm EC- Series

Indirect fired oil heaters engineered for efficient, clean, and dependable heat in demanding industrial and commercial environments. 

Includes Preheated Fuel Filter, Single Fuel Line Kit, Upgraded Fuel Lines, Chimney Kit, Chimney Holder Kit

Engineered for Superior Efficiency: A proprietary four-loop heat exchanger extends the exhaust path for greater heat transfer, delivering up to 2% higher efficiency versus traditional three-loop designs and as much as 10% more usable heating power. Hot gas passages operate at lower temperatures, protecting components while maximizing performance.

Clean, Safe, and Reliable Operation:

• Built-in oil burner with electronic flame control for precise, consistent combustion.
• Safety-first design: overheat thermostat, pressure switch, and double-skinned combustion chamber.
• Two-stage startup with pre-purge and post-ventilation cycles for smooth, reliable ignition—even in cold conditions.
• Stainless steel heat exchanger for long-term durability and corrosion resistance.

Ready for the Job Site:

• Integrated fuel tank for extended runtime and a twist-lock cap with leash for easier fueling.
• Pneumatic tires and a mobile chassis for straightforward transport and positioning.
• Internal thermostat for on-the-fly temperature control and steady comfort.

Fuel Flexibility: Compatible with Diesel, Kerosene, Fuel Oil, JP-8, and Jet A fuel to match your supply and operating needs. A pre-heated oil filter supports smooth operation across models where equipped.

Why it’s a smart choice: By combining advanced heat-exchanger technology with robust safety systems and easy mobility, these indirect fired heaters deliver powerful, clean, fume-free heat to enclosed or ventilated spaces such as construction sites, warehouses, workshops, and event structures—without introducing combustion byproducts into the air stream.

Key benefits at a glance:

• Higher thermal efficiency and heating output from a four-loop design.
• Clean, ductable air for occupant comfort and material protection.
• Reliable cold-weather starts and stable flame control.
• Rugged build for industrial duty with low-maintenance components.

Choose an indirect fired solution that prioritizes efficiency, safety, and uptime—purpose-built for professionals who need dependable heat, day after day.

1) Reinforcement Supports w/ Gusset, and Long Carrying Handles w/ Gussets that provide obvious lifting points at the front and back of the heater (and the sides on the EC 300) making it easy to pick up and load in and out of a truck, van, etc.;
2) Additionally, the Long Carrying Handles run the length of the fuel tank thereby increasing the rigidity and durability of the heater overall;
3) Designed for frequent moving, lifting, etc. (ie. going into ‘combat’)
