Please contact MHI for Airtorch™ and Airtorch™-recuperation uses. Smart Recuperaters,
Typical Applications include Simulation, Chemical Reactions, Heating Reactions, Drying, and many more.
Simple 5-step selection guide and flow as a function of temperature for various models.
Suggested Uses: Process gas heater, gas heater, decarbonizing heater, gas preheater, air preheater, supplemental heater, and many other process-heating applications. See Applications
The required kW depends on the exit gas’s temperature from the Airtorches® and the flow volume needed. Please use this formula to calculate the approximate temperature vs. flow rate for a fixed power or an Airtorch® model number. MHI also provides flow rate vs. temperature. Request graphs here.

Typical Applications for Airtorch®:
- Several applications are in high-pressure test stands for automotive and jet engines— key Features: Long-lasting, high temperature, high energy conversion, high pressure, and compactness.
- Electric hot air generators are often used to heat commercial and industrial environments. Several applications are in energy-efficient comfort heating. Key Features: Compact, long life, and rapid heating.
- Several applications in chemical processes and drying. Key Features: Energy efficient, extremely compact, controlled high temperature, and rapid heating. Airtorch® nano-structuring is used for gas combinations like hydrogen, methane, or syn-gas where combined catalysis action is enabled.
- Use in Ammonia, Cement, Steel, and General Heating Industries
Each type of application has its unique control system designed for that market.
MHI Airtorch® systems offer patented low-pressure drop technology called the Direct Flow method—industry-leading quality, price, and delivery. Several models are displayed below. Units for 750°C,925°C, 1000°C,1100°C and 1200°C. The typical Airtorch® use is illustrated in the Airtorch® Infographic.
Why are the MHI Airtorch models efficient? Prices are scaled with power, temperature, and pressure. Please discuss your best value with MHI. The following classes are available: Flow GTA – For high-pressure vessel Airtorch use—custom engineering. Please contact us directly for assistance.
Airtorch™ and LTA’s may be purchased with several exit configurations generally shown on the specific web or catalog page. In addition, further customization is also possible.
