Electric Airtorch®
Electric process-air and process-gas solutions for meeting the industrial sector’s stringent targets for zero-carbon emission and deep-decarbonization with high energy efficiency.
An Airtorch is a device that heats air and other process gases to temperatures ranging from 20°C to 700°C /800°C /900°C /1000°C /1100°C /1200°C /1300°C. This is one of the most compact decarbonization industrial heating methods with high energy efficiency. The Airtorch uses a convective system to heat the ambient air and direct it towards a surface or into a chamber. The Airtorch can be used for high-temperature industrial processes such as iron-making, cement-making, aluminum, magnesium production, general high-efficiency heating, food and liquid heating, and glass furnace decarbonization. The Airtorch can improve the efficiency of many chemicals and energy production processes. The price of an Airtorch goes up with the demand for power, temperature, and pressure ratings requested.

- Unlike combustion-powered devices, the MHI Electric Airtorch® does not produce greenhouse gases (like CO2, Methane, or NOx).
- When converting from combustion heaters to electric heaters, a 30% energy efficiency improvement is expected. MHI Airtorch® models offer patented ultra-low pressure drops with flows that enhance relative efficiencies and low product distortion.
Electricity-powered units prevent approximately ~0.2 to 0.7 Kg/KWh of CO2 production at the Airtorch site compared to combustion units. Additional energy savings are enabled with the ultra-low pressure drop technology, which features Ultra-low pressure drops, high turndown ratios, and an outlet temperature of 20°C-1200°C. One will experience low-pressure drops in high-pressure enclosures with fully stamped ASME, UL, ATEX, and CE codes. Rapid temperature-rise units add to lower energy consumption.

The Airtorch® is a highly efficient scalable electric process air/gas heater. MHI Airtorch® systems offer patented low-pressure drop technology called the Direct Flow Drop with industry-leading quality, price, and delivery.
A low-pressure drop equals savings in energy costs. For a 2000 SCFM flow, saving ~5 psi in pressure drop equals about 30 KW in power savings, a savings of ~$25,000 per year.
A high-temperature capability also equals savings in energy and productivity. MHI provides units for 750°C, 1000°C,1100°C, and 1200°C. The typical Airtorch® use is illustrated in the Airtorch® Infographic.

Very High Temperature
Operating Temperatures to 1200°C/~2150°F. DPF models can take fan or blower input and a compressed air/gas input.
Important volumetric conversion.[ 1 m³ = 35.315 ft³ ]
MHI special technologies allow for the following:
- Incredible Warranty.
- Inlet temperatures can be high on specific models of MVTA.
- Pressure drop: Very Low. MHI offers DirectFlow™ Airtorch.
- We use our combined thermal knowledge across diverse equipment offerings to optimize and provide low-friction Airtorch systems.
- Quick Selection Guide: If the flow rate is 2-40 scfm, please choose MTA, VTA, or LTA models or the MVTA925 models with flanges. If the flow exceeds 40 scfm, please select from the highly energy-efficient MVTA models.
- If the temperature required is above 1100°C, please choose the DPF models.
- When comparing Airtorch heating to other methods, please note that the MHI Airtorch systems do not produce appreciable sound.
Quick Units-Conversion : (800°C=1472°F) (925°C=1697°F) (1000°C=1832°F), (1100°C=2012°F) (5 Bar=0.5 Mpa)
Need higher temperatures? Please don’t hesitate to give us a call or contact us. The required kW depends on the exit gas temperature from the Airtorch™ models and the flow volume needed. Please use the Easy Design Criterion or this formula to calculate the approximate temperature vs. flow rate for a fixed power for an Airtorch™ model number. MHI also provides flow rate vs. temperature for TA and DPF models—request Graphs.
Allowed Air/Gas Inputs: Air/Gas from the compressor, blower, or fan may be attached (varies by model). Depending on the model, input such as Gas Cylinders, Compressors, Blowers, and fans may be used. Some Airtorch® models also accept high-temperature feed gas as an input. The Airtorch® models are highly efficient electric process heaters (inline, cross line, and independently standing models are offered). DPF models have very low-pressure drops associated with them.
Airtorch Operation: The flow rate and temperature are connected. The heater cannot go beyond its rated temperature or power. The thermocouple is integral to the heater. The principle of an air/gas heater is for flowing gas to heat within the residence time of the heater/configuration. The flow temperature curve is given on the Power Vs. Flow Calculator. This is shown for air and can easily be converted for different gasses and supercritical CO2 (sCO2) recuperators for a Brayton cycle demonstration.
Flow Rate is Important: If using a blower or fan, the airflow will be controlled by the fan’s or blower’s characteristics. Fans are employed when the system’s pressure drop is no greater than approximately 50 in. w.c. (50 in. w.c./inches of H20 is approximately 1.8psi.) This condition remains true even when the fan outputs large CFM values. Blowers are considered in circumstances where more significant pressure drops are present.
Every MHI Airtorch has a maximum power rating, temperature, and pressure rating (if rated to higher than one atmospheric pressure, i.e., the GTA models). Please follow the curve on the Easy Design Criterion while operating safely within the device ratings. The power should be fixed close to the rated capacity. Please maintain a low flow cutoff sensor if used close to the highest-rated temperature. Please observe limits with care. MHI Airtorch models have multiple control and safety thermocouples and other safety devices.
Whether to use a Compressor or Blower? Ans: The Airtorch units accept all types of inputs. Please contact MHI to check whether a particular blower or fan is suitable. The most crucial issue is not falling below the minimum SCFM rating or temperature for the maximum rated power. Fans are employed when the system’s pressure drop is no greater than approximately 10-50 in. w.c.
