Airtorch® Air and Gas Heater Models by Category

Several electric process heater models are available in each class (Kilowatt to Megawatt models)

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 UsesProcess 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.

Multi Door Control Panels and MW Airtorch with Vert

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°C1000°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.
