Our team is
Ready to help!

This field is for validation purposes and should be left unchanged.

Crown ERAM’s experienced engineering team detects any issues and will develop a new design parts to advance current capacity of the system.

With proper maintenance, industrial circuit breakers can last for decades. Crown ERAM’s technicians thoroughly inspect your switchgear with all applicable tests.

We test all varieties, sizes, and types of motors, effective in all electrical fault zones for reliability, quality assurance, trending, or fault-zone diagnosis

We scan your equipment functionality safely and quickly. Our Ultrasound non-destructively detects partial discharge and electrical corona while the Thermographic Survey measures passive infrared radiation without down time.

Crown ERAM provides industry-compliant safety education with documented hands-on on-site and performance-based training that is readily available at any location.

We disassemble the machinery, clean components, and replace worn-out parts. It is then reassembled and re-tested. Our machine shop fabricates replacement parts if necessary.
