Gene Mantei, Phase Technologies

It is not often you meet someone who knows more about a product than the manufacturer. At Kay Industries it is that way. They know our digital products, they understand the customers application, and even though they make rotary phase converter they do not strictly offer their own products. Amazing, trustworthy, and the ultimate source for all things three phase.

James Burt, CED - Burlington

Super nice people who really know their stuff. They are a little more expensive, but you pay for what you get. Plus, their service from start to finish is unmatched.

Justin Greenfield

We have called on Kay Industries for help getting a phase converter for several pieces of construction equipment at varies job sites. They always answer the phone friendly, have great knowledge, and are very professional. On one project, I remember Donnie going above and beyond to make sure we got the installation right. Rob is great at follow-up, John, Larry (now retired) Matt, and Jay are real (3 Phase converter) experts. I have been a happy customer each time. I will definitely buy again, and recommend them anytime.

Ron Permenter
