Mission Critical Preventative Maintenance Program

ESM engineers provide preventative maintenance, trouble shooting and repair services on mission critical systems including: Generators, ATS, UPS, Batteries, high voltage, medium voltage substations, switch-gear, MCC, UPS and control equipment. We offer single and multiple year maintenance agreements for Uninterruptible Power Supply (UPS) systems, DC Battery systems, DC Chargers, Power Distribution Units (PDUs), Static Switches and Cathodic Protection Rectifier systems.

We have hired several former employees from some of the largest original equipment manufacturers (OEM) in the country. As a third-party vendor, our field engineers are not only factory trained but  experienced trained. We have the benefit of specializing in a wide range of products; therefore our engineers are able to consider your entire critical distribution block as one system.
