Airtorch™ Applications

Airtorch™ System Introduction

Easy Design and Selection


Choose KW, MW and even MW/m2 flux


If the flow is higher than 40 scfm, please choose from MVTA models

If the temperature required is above 1100°C please choose DPF models

If the flow rate required is is of the order of 2-40 scfm please choose from MTA, VTA or LTA models or MVTA925 for flanged units

1- 15 Kw 36 KW, 72kW , 144kW,  402 Kw, 900KW, 3 MW


Other MHI products like OAB® and Cascade e-ion also may also be used for such applications

Use powerful Airtorch for continuous VOC removal or use for rapid heat treatment and/or surface treatments like finishing to hardfacing.

The Airtorch™ can be used for curing, surface burning and sealing and simulation operations. The possibilities are endless as Air, Nitrogen, Helium and Argon can be used.

During combustion the time for 98% combustion can change by several orders of magnitude for 100K rise in air temperature. Arrhenius equation and influence of Temperature.


Fuel Cells, High velocity drying and surface heating including simulation.  Contact MHI for Nozzles supplied.

Large Die Heating/ Rapid Dry
Direct Ceramic Drying

The Airtorch™ allows large die heat-up; reclaim dies and aluminumCombustion/flow simulation, curing, dryin or bonding of paper boards.  Removal of inorganic and organic salts, fuel celss, general heat treatment fr bending and deflashing/deburring,, drum heating, plastic rolls, welding organics like plastic soldering disinfection, drying, rapid paper and pulp  dry. With a 4 kW machine  plan to dry 2-4 Kg/hr of desiccant.

Please contact MHI for ROI calculations for typical Die Heating

Free and bonded water can be easily removed. The Airtorch™ can achieve very high temperatures without contamination, therefore direct drying is a natural application. MHI also manufactures several Airtorch™ Continuous ovens. Small Airtorch Augmentation for Heat Treatment Furnaces- typical ROI.


Binder Burn-Off.  Heating for Tensile and Fatigue Testing
Direct VOC removal possibilities

Easy, uniform, safe, and collectable binder burn off. For ceramics, nitrides, powder metals, etc. Substantially improve quality and productivity.

When high temperatures are needed in spaces where resistance heating elements cannot be used, the Airtorch™ provides the solution.  Temperature variations matter during adhesive resin curing. Temperature profiling is particularly is important with an 8 Data Log during start up and cool down. Airtorch is instantaneous and uniform. OAB steam is instantaneous. Hybrid.

The operating cost estimate per pound of VOC removed is about ~0.5¢*, for normal ppm contamination concentration removal. Compare with over $4/lb. Please contact MHI to verify calculations

* Estimate only- subject to change.  The estimate will vary by application,  VOC removal consideration price is considerered primarily from gas stream only.  All ROI's require a 30 day assesment as the assesment may not be current.

Packaging or Sealing
Die Heating
Designed for long life and high temperatures, the non-contaminating Airtorch™ is an ideal solution for inline packaging or sealing processes.

Use the Airtorch™ as a preheating device for dies in the metal forging and rolling industries.

Soldering, Blanketing, Melting and Dental

Use the Airtorch™ for softening, soldering, and melting of precious metals and glass. This feature is very applicable to the dental, jewelry, and glass industries. Use for rapid glazing, burnout and quick melts.

Continuous Furnace and Roll Augmentation

Heating: Create a convective cavity around the assembly using two 4kW Airtorch™ units. Fixture Airtorches™ behind mold and electrodes at angles to create air movement. This should improve the overall heating of the mold.

Insulation: The assembly is surrounded by refractory blankets (all 5 sides) to retain as much heat inside as possible. Blankets can be supplied by MHI at customer's request.

Solution: By supplementing the existing electrodes with the Airtorch™ and blankets, the watt density is increased on the mold thus reducing the workload of the existing electrodes which should improve performance and life. Other results include an increase of uniformity across the mold surface. Call MHI for more information.
