Preventative Maintenance

Whether you are talking about your family vehicle, a widget factory or an electrical substation a robust Electrical Preventive Maintenance (PM) program is the very foundation of reliability. Besides safety and reliability, some studies show that unplanned maintenance costs can be up to six or seven times the costs of planned maintenance, or issues corrected during PM. We can evaluate your equipment and create PM programs that meet manufacturers’ and industry specifications in regards to the types of tests, intervals and more. ANSI, NETA, NFPA, OSHA – we’ll take the mystery out of required and recommended Preventive Maintenance. Whether you are in need of a simple Infrared scan (IR) or a complex Shutdown, Turnaround & Outage (STO), we’ll be there to manage every step of the process to make sure ensure your equipment runs safely, efficiently and reliably.

We can also support you and your teams with the following Field Services.
