Convective Heat Treating

True Convective Heat Technology

We would like to introduce to you the MHI Airtorch™, the only energy efficient universal convective heat source. By itself, the Airtorch™ can rapidly heat any part up to 2000°F. It can be used as either a stand-alone heating device, or an integral component of a convection oven. This makes the Airtorch™ an incredibly versatile product.


What Makes Airtorch™ Special?

The Airtorch™ produces convective heat to 2000°F without air or noise pollution. Powered by electricity, it provides up to 70% more energy efficiency over conventional gas ovens.*

What Does This Mean For Heat Treaters?

Consider the Airtorch's™ (Airtorch™ 6.5/10.5kW models) high power and superior uniformity. A batch, conveyor, or continuous pusher furnace utilizing our technology will allow heat treaters to process more parts faster, with substantially less part failure caused by non-uniform furnaces.

Retrofit To Add Value And Performance

MHI recognizes that the Airtorch™ will improve the value and performance of many furnaces already in use. One can easily retrofit any existing oven structure with the Industrial Airtorch™ because of its unique design. Heat treaters can upgrade existing furnaces or use the Airtorch™ by itself for a variety of applications.

MHI's design team can provide complete engineering designs to help you build your own Airtorch™ oven. We can design and manufacture custom furnaces, tailored to your specifications. Call our sales engineering team today to learn how the Airtorch™ and Thermoblower™ can revolutionize your process as well as your bottom line!
