Spare Parts &
Replacement Parts


With the financial times that we are all having, companies tend to underestimate how integral it is to have parts on hand to keep their systems up and running. It is also difficult to keep the inventory that we need. We would all want our systems to run fault free forever, but we all know that is impossible.

We are here to help in times of breakdown situations when you are looking for that specific part. We can supply you with all the parts from all the major manufactures of AC Drives, DC drives, fuses, silicon controlled rectifiers (SCR’s), Circuit Breakers/Molded Case Switches… (see our list of parts). We are not limited to just those items on the list, give us a call at (815) 725-9696, whether you are looking for replacement parts or spare parts, we can supply you with what you are looking for.

Spare parts are something that never gets a second thought, because nobody wants to spend money on parts that are going to sit on a shelf. If most companies took the time to calculate their losses when they are down compared to what it costs for spare parts, they might think twice.

When you have a breakdown situation you have to look at how much production costs you lose per hour, per day or however long you are down. You not only have to look at the cost of lost production and the freight costs to have the new parts flown in, but also how many people do you have standing around not being productive because of downed machinery.

We are not recommending you have a spare part for every part in your system, we suggest that you stock just the main components such as the main printed circuit boards, SCR’s and fuses, it varies with each system. Give us a call at (815) 725-9696, if you’re not sure what you need, we can evaluate your system and give you a recommendation on what we feel you should have on hand.
