Choose MHI Airtorch® and Jet Heater Models when the requirement includes:

  • High turn down
  • High energy efficiency. At 900°C, what does the competition offer as a flow rate? At 1000°C? At 1100°C? At 1200°C?
  • Very low-pressure drops
  • Compact units
  • Rapid heat-up and highly stable temperatures
  • MHI uses patented nanostructure surface protections
  • Unique HE designs for gases such as hydrogen or mono-silane for the solar industry.
  • High-quality torispherical terminations on pressure vessels.
  • High damage tolerance.
  • MHI Electric Airtorch® products offer multi-stage heating.   Save substantial operating costs over gas heating.

    Sometimes, the efficiency of electric Devices is far greater than that of fossil fuel-fired heat exchangers (compare 10 MW to 16 MW in one application).

    Compared to fossil heating, 1 kWh of electric heating saves almost ~0.5 Kg of CO2 from polluting the atmosphere.

    This is particularly important for several unique gas-heating solutions for decarbonization and climate change.

    • Heavy duty with very low-pressure drop.
    • Outlet 1200°C and above.
    • High-pressure enclosures.

GTA / GVTA is ideal for demanding high-pressure applications such as:

  • High-pressure engine sensors and exhaust
  • Auto and jet engine test stand
  • Reactors (industrial preheating)
  • Combustion systems
  • Replace combustion burners with Airtorch
  • Drying of fluids
  • Drying of powders and ores.
  • In-line duct heaters with incredibly low-pressure drops
  • Simulation testers
  • MVTA, GVTA, and GTA are often used for combustion (simulation)
