Compare energy efficiency. Efficiency improvements by innovative design, advanced patented heating materials, and the sturdiness of construction. What does the competition offer as the maximum flow rate for a fixed power at any temperature? MHI can sometimes even be 100% better. Why trust anything else?
Unlike combustion-powered devices, the MHI Electric Airtorch® does not produce greenhouse gases (like CO2, Methane, or NOx).
Typically converting from combustion heaters to electric heaters, over a 30% comparative energy efficiency is expected. MHI Airtorch® models offer patented ultra-low pressure drops with flows that enhance relative efficiencies and low product distortion.
Electricity-powered units save approximately ~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 and feature Ultra-low pressure drops, high turndown ratios, and the 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.

Why are MHI Inc. Airtorch® units so compact and powerful? The various Airtorch ®models are a product of intense R&D effort and customer acceptance over the past decades. Surface enhancement nanotechnologies, optimized high-impact heating materials, unique design, and efficient control electronics are uniquely deployed in Airtorch® systems. MHI Inc. holds several modern patents in materials and heater designs.
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.
Why choose the MHI Airtorch®? Low operational cost because of very low-pressure drop (~1psig, much lower for Duct Heaters), noise-free, quick-start, high temperature capable – which also implies longer life at lower temperatures when compared to process gas heaters that cannot reach high temperatures. Several models in stock – all quality engineered and carefully manufactured. MHi has decades of electrical heating experience.
The typical Airtorch® model output is up to 1200°C (~2150°F), depending on its rating. They offer high flexibility and good control of process heaters. Room temperature is assumed as 25°C for standard input in most models – whereas the (HI) models allow even a 600°C input. Single Phase Power to Three Phase Choose from 1KW, 3 KW, 4 KW, 12 KW, 24KW, 36KW, 60KW, 120KW, 144 KW, 180KW, 216 KW, 300KW,400KW, 1 MW, 2.2 MW, 4 MW and higher. Choice of pressure vessels.

MHI special technologies allow for:
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,orLTA models or theMVTA925 models with flanges.If the flow is higher than 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.
Need higher temperatures? Please don’t hesitate to give us a call or contact us. The kW required depends on the temperature of the exit gas from the Airtorch™ models and the flow volume needed. Please use 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 Power Vs. Flow Calculator. This is shown for air and can easily be converted for different gasses and supercritical CO2 (sCO2) recuperators used 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 drop in pressure of the system 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, a maximum temperature, and a pressure rating (if rated to higher than one atmospheric pressure, i.e., the GTA models). Please follow the curve on 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 are provided with multiple control and safety thermocouples plus other safety devices.
Whether to use 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 drop in pressure of the system is no greater than approximately 10-50 in. w.c.
