Airtorch™ System Introduction and Flow Charts. Use for continuous VOC removal or use for rapid heat treatment and surface treatments like finishing to hardfacing. The operating cost estimate per pound of VOC removed is about ~0.5¢*for regular ppm contamination concentration removal. Compared with over $4/lb. Please contact MHI to verify the 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 several other features. Contact Us or See More Information for more information about MHI’s control panels. | 
XPAN (Several Configurations) |
 |
|
| MHI Data Acquisition and Control Software (MHI DACS) | |
| MHI devices are compatible with MHI DACS for furnace controls, step programming, data logging, and more. DACS also allows for remote furnace control, allowing one central location to control multiple devices.
We are now offering DACS – Ver. 8.1 on select Panels – standard.
