MHI Electric Airtorch® products are compact and energy efficient.
Save on operating costs over traditional electric or gas heating.
Click to learn about decarbonization and energy efficiency.
Save on space, e.g., a 15 MW is only about 6 m long.
New MHI Array heaters for 50 MW and above.
Electric devices’ efficiency is often better than fossil fuel-fired heat exchangers (compare a 10 MW substitution for a 16 MW fossil fuel system).
1 kWh of electric heating saves almost ~ (0.3 – 0.5 kg) of CO2 equivalent emissions per hour.
This is important for decarbonization to assist climate change and reduce global warming.

Why choose the MHI Electric Airtorch®? Efficiency, Temperature, Construction-materials, and Life-cycle cost calculations.
Low operational cost from the very low-pressure drop (~0.1 PSIG, and much lower for Duct Heaters), noise-free, quick-start, high Temperature capable – implies longer life at lower temperatures than process gas heaters that cannot reach high temperatures. Several models in stock – all quality engineered and carefully manufactured—decades of electrical heating experience. The high-power patented three-phase Airtorch® configuration yields high-temperature convective air and may be used for various applications. Use for surface heat treating, simulation, combustion tests, reaction engineering for carbon and calcium, cement, forestry, steel, ammonia industry use, Other environmental decarbonization uses like preheating, drying, powder sintering, testbeds, channel heaters, and large and continuous ovens. MHI Airtorch® systems are extremely energy efficient. Stainless steel or other flanged sealed systems provide both energy efficiency and conservation.
