Airtorch™ Overview:
The Airtorch™ is used for several modern direct heating configurations (see typical application pages in Airtorch™ Handbook available free from MHI). Airtorches™ are also used for augmenting or heating existing ovens and furnaces. They offer high flexibility and control of any heating process. Input of air or gas may be from a compressor, blower or fan (depending on the model). MHI offers several categories of Airtorches™ such as LTA's (generally 900°C and below), AT models up to nearly 1200°C and Plasma/Ultra-Torch™ models up to nearly 1500°C. Several MHI Airtorch™ models accept high temperature feed gas input. LTA's accept line voltage. Some Airtorches™ may require feedback controls which are easily available from MHI. The kW required depends on the temperature of the exit gas from the Airtorches™ and the flow volume required. Please see formula to calculate. Please obtain flow rate vs. temperature graphs for individual Airtorches™ from MHI. Airtorches™ and LTA's may be purchased with several exit configurations which are generally shown on the specific web or catalog page. In addition further customization is also possible.

Article Brief: Convective Heating for Ovens

75% Improvement in Energy Efficiency/Elimination of Distortion.

A comparison of the benefits of heating by convection and radiation at temperatures below 1000°C (1830°F) is presented in this article. The convective heating data is for a nonpolluting furnace that uses an electrically powered, ultra hot-air/ gas generator. The Airtorch source quickly and efficiently produces hot air or inert gas heated to temperatures as high as 1000°C (1830°F). The complete article is available in the October issue of ADVANCE MATERIALS & PROCESSES magazine (pages 213 to 215,10/1999). Read complete article and other similar articles. Article - 1.

Airtorch™ Continuous Oven

* MHI will honor the calculations made by your furnace consultant or OEM for power, flow and process applicability when using or retrofitting a non-MHI furnace. However the responsibility of the calculation rests with your consultant. MHI cannot recommend power for any Airtorch retrofit as the complete details of your furnace (e.g insulation, furnace load, exact process details etc.) may not be available to MHI. MHI is responsible only for the proper working of the AirtorchTM unit in a stand-alone condition as supplied. MHI is not in a position to discuss applicability for your individual process except in broad general terms, if at all. If you have purchased a complete furnace from MHI including controls then MHI will provide its standard guarantee as applicable. However MHI also gives you the option of purchasing only the the components you may want to purchase from MHI. Therefore, alternately for customers who purchase only the Airtorch™ Units or Controls seperately, or for a retrofit, MHI will still work with you or your furnace consultant/OEM for explaining Airtorch™ safety, use, any start-up issues, and other issues only if MHI is in a position to do so for your application.

Please contact MHI to design the best
solution for your application.
