| The DPF Airtorch™ line is a line of highly efficient process air heaters, capable of producing air up to 1200°C/2200°F. Users enjoy accurate temperature control, versatility and quiet and clean operations. DPF Airtorches™ may be used to dry, cure, shrink, seal, braze, anneal and a number of other processes requiring high temperature hot air. Convective heating is the most versatile way of delivering heat as it is not limited by line-of-sight. DPF Airtorches™ deliver heated air/gas up to 1200°C/2200°F when used with a ~70°F inlet gas temperature. Contact MHI for pressure ratings. Which DPF to I need? First asses the power required, then employ the following design criteria for air ~ about 2.6 SCFM/kW of convective heat transfer. Call MHI for confirmation as this an approximate number only. Please adjust power requirement to consider any losses in your delivery piping. DPF Airtorches have 1.5"-2.5" NPT Exit Nozzles, depending on model. The DPF models accept user-provided Blower or Compressor driven air/gas input. Our DPF Airtorch™ line is easily integratable into existing process systems or may be used as a stand alone heater or air preheater. Potential use includes cable conveyors, bucket elevators, screw conveyors and pneumatic systems. Airtorches™ offer flexible layouts, gentle product handling, higher throughput, small footprints and higher energy efficiencies in an enclosed, dust resistant system. Airtorch™ devices can easily be integrated into existing systems. MHI Airtorches offer a wide array of use temperatures and other flexibilities. Please Contact Us or Call 513-772-0404 today! |

Inlet: 3kW DPF Airtorch™ |
The 3kW Line of DPF Airtorches™ allow for high temperature process heating at moderate flow rates. (Compared to higher powered DPF Airtorch™ Models.) All DPF models feature high efficiencies, easy integration into existing systems and low emissions. Not only can an MHI Airtorch™ improve your process, it can also save you money in the long run. Which DPF to I need? Simple design criteria yields and estimate of about 2.6 SCFM/kW for the high efficiency MHI DPF Airtorches. Please contact MHI for confirmation as this an approximate number only. |
