"Your elements have lasted at least 3X of the original mfg."

C. K. , OH
"I’ve been using your elements for a long time and I have no complaints everything is working well."

Researcher, major US University
"...used at 1450°C... MHI MP1800 elements... ran over 2000 cycles... best ever seen by a long shot."

Researcher at another major University
"Now using in 7th year."
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. Users should recognize that the life depends on maximum temperature of use and other factors. MHI elements reach 1900°C... are we your supplier? (also see our articles in Technical Articles on how to choose the best element for maximum productivity).

Tim B, GA
"You make them so good, no need for replacement elements. It's scary, they're still going..."

William S, Illinois
"I'd like to thank you (and MHI-INC) for your efforts. I would like to let you know that I enjoyed working with your company. Your response time was very fast and you had the lowest price, XXX was second, and then there was XXXXXXX (who never called us back after repeated inquiries.)

Thanks again."

JZ, USA

Leo M, Pennsylvania
"We are very happy with the heating elements, the MP1800™ last for us. MHI has supported us completely with very good service."

"I would like to thank Kevin and MHI for recommending the use of Nickel coated elements. These new elements have been very successful in our process. We could not perform our Preventative Maintenance on our ovens without the use of these elements. When we would check our connections we would break the ends of our elements due to the fact that they would adhere to the elements that are connected to braided straps. It's been a great help. Thanks again, Leo."
