Mean Time Before Failure Analysis
Understanding your MTBF helps us build a service schedule around your equipment's actual lifecycle, replacing components proactively rather than reactively.

Preprogramming Services
Knowing the right parameters and settings for your controls can mean the difference between preventing a catastrophic failure and having one occur. Our experienced technicians pre-program your controllers with factory-approved settings — protection settings that are typically missed or left at default are configured to provide optimal application protection. The peace of mind of a tested, fool-proof system makes all the difference.
PLC Automation & Panel Testing
We test all Automation, UL 508A, and UL 698 panels before they ship. PLCs inside our panels are programmed and tested against all possible process variables, proving their capabilities before the complete panel leaves our facility. Customers are welcome to witness the test process in-person — we encourage collaboration and welcome ideas on changes and improvements as we design the process to meet your specific needs.
