Airtorch™ System Introduction and Flow Charts.  Use for continuous VOC removal or use for rapid heat treatment and/or surface treatments like finishing to hardfacing. The operating cost estimate per pound of VOC removed is about ~0.5¢*, for normal ppm contamination concentration removal. Compare with over $4/lb. Please contact MHI to verify calculations.

Electronic Controls

MHI’s DPF Airtorches™ are compatible with our electronic control panels and DACS software. Standard features include overtemperature controls and programmable steps. In addition to standard electronic controls, MHI DACS allows for remote furnace monitoring, data logging and intricate step programming.

MHI Airtorch™ Controls
Many of MHI’s electronic furnace controllers feature multiple voltage inputs, overtemperature controls, programmable cycles and a number of other features. For more information about MHI’s control panels, Contact Us or See More Information.
