Who We Serve
Critical power fails the same way in a hospital as it does in a hyper-scale data center. What changes is the regulatory environment, the maintenance window, and what an outage actually costs. Those differences are what we plan service around.
Our ExpertiSe
Specification, installation, maintenance, and the engineering studies that keep it all compliant. All handled by one team, under one point of accountability.
Our Service Coverage
Orange denotes a dedicated Account Manager & 24/7 emergency phone support.

01. Expertise
UPS Field Service Engineers
In critical power, a service agreement is only as good as the person who shows up. Ours arrive factory-trained on the platform in front of them, certified to work it safely, and positioned close enough to key markets to be on site fast when something fails.
02. Expertise
UPS Services
Four service programs covering the full lifecycle of a UPS: scheduled maintenance, emergency response, service agreements built around your budget structure, and documentation that tells you what actually happened.
03. Expertise
Asset Management & Analytics
We use asset data to right-size your SLA, so the scope of work fits what your equipment actually needs — not what’s convenient for us.
04. Expertise
Comprehensive Battery Solutions
Batteries are the part of a UPS system that’s guaranteed to fail, the only question is whether it happens on your schedule or theirs. We test, plan, replace, and dispose of them so the answer is always yours.





the right parts, in the right place, at the right time.
Our warehouses (Madison, Dallas, Houston, Detroit, Orlando, and Toronto) stock more than 15,000 OEM and aftermarket components: fans, fuses, contactors, capacitors, circuit boards, and batteries. Over 20 years of service data tells us which parts fail on which platforms and when, so what sits on the shelf is what a failing UPS is most likely to need.
We also supply new, refurbished, and rental systems across single- and three-phase UPS and lighting inverters.
