MHI Airtorch®

G. G., Lead Engineer, Major US Controls Company.

Thanks a lot. I was having a hard time with my RS485 to USB adapter, so I wasn’t looking forward to fighting it…how to power up the PLC safely, either. Now, I can do the majority of the DCS troubleshooting before needing to get in the cabinet.

K. W. Professor, Leading University in the Western USA region.

I am impressed by the quality of the heaters and associated electronics!

C. P. Lage Consultancy Project Group, USA

That system utilized an air torch as part of a continuous process very successfully — a series of airtorches instead of a series of 2 MM BTU natural gas burners.

A.M. Principle Engineer at Large Aerospace Corporation, USA
The low-pressure drop and compactness of your Airtorch® are out of this world.

VP of a Rapidly Growing Multi-Million Dollar Company

Your group (MHI) is the only company that can do this higher temperature with proper controls and long-term reliability that I have been able to find.

Your quotes were indeed submitted on time, and your product is good.

D.S. Senior Engineer at a US National Laboratory. USA

We received our system this week, and I’m unpacking it. The components look very nice, and I’m pleased with the detail and how you have designed the controls with so many built-in protections. We are excited to get this integrated with the rest of our systems.

L.S. Distinguished Senior Tech at National Laboratory, USA
You are the Best!  Thank you very much for your support.

“We ran one of the inserts on 17-4 stainless steel on our CNC lathe……..The coating did seem to make a difference. I would say at least 15 to 20% better than without it. I ran the small insert on 1045 steel. bored 40pc with 2 passes for each bore. One thing I noticed right off the bat was,the coating gave an improved finish over a standard insert finish. I did not have to change insert and finished all 40 pcs without the tool breaking down!”

Note from MHI — We have been aware for some time that our elements are the best in the world, based on customer feedback. However even we were surprised by the life some users are getting from them.

We could not perform our Preventative Maintenance on our ovens without the use of these elements.

Thanks again, Leo.”
