Engineering Services

Many electrical failures are caused by mechanical defects that can include the wrong lubrication, bearing wear, metal fatigue, out-of-balance vibration and misalignment. So to repair equipment correctly, we fix both the mechanical AND electrical defects.

We appreciate that machine downtime costs you money. That’s why our in-house engineering division is committed to quality workmanship and quick turnaround. We’ll go the extra mile to get the job done even faster for those crucial breakdowns.
