In this economic climate you need to get the most for your buck. This is the time to make those improvements you need to save energy, cut cost & stay competitive. Waiting will only cost you money. Contact Joliet Technologies today.

  • Wouldn’t it be great to upgrade your equipment, improve production, cut operating costs and still stay within your budget?
  • Retrofit your old, outdated equipment with new digital drives at a fraction of the cost of an entirely new system.
  • Plus 24/7 service and technical assistance.

These are the problems you’re faced with every day. Solutions to your problems aren’t as difficult as you think. What you need is an experienced work force to work with you “one on one” to find the solutions.

Do you have ac motors in your facility?
Do these motors need a variable output?
Do you use mechanical means to vary the output?
If you answered yes to these questions, you need to install variable frequency drives on these ac motors.
If you are not using VFD’s you are wasting energy and throwing money out the window.


Thanks for retro-fitting our two main Robicon DC Drives with Siemens Digital Drives. We came in under budget. Which makes Joliet Technologies a fine company to work with.

Dear Valued Client,

Do the names Bob Meade, Clay Johnson, Greg Thornton or Phil Cheshareck sound familiar to you? Here’s a hint. They were employees of a Joliet, Illinois based company specializing in industrial variable speed drives and controls, which you may have done business with in the past. (Because I can’t use the name of the company I’ll refer to it as the “Previous Company”).

There’s Good News,
We Started Our Own Company!

After months of negotiations, discussions and planning to buy the drives division from the Previous Company, Bob, Clay, Greg, Phil and myself came to the conclusion that the Previous Company did not share the same concerns, values, and philosophies as we did. Together, we thought you deserved better overall service. After we were locked out, terminated, and negotiations broke down with the Previous Company, on June 3rd 2002 we decided to create Joliet Technologies, L.L.C.

Joliet Technologies 10,000 sq. ft. Facility in Crest Hill, Illinois.
