Electronic Support Systems ESS is a manufacturer's representative with a complete line of high-quality precision environmental, We have been a member of the Electrical Board of St. ft.

Electronic Support Systems (ESS) is a manufacturer’s representative business offering a complete line of high quality products to support electronic equipment. Our product line covers your power protection, power conditioning, and precision environmental needs. We will provide clean, reliable power, and cool, conditioned air to maintain our customers systems 24 hours a day, 7 days a week, and we s

upport the full range from very small sensitive systems, to larger, more complex systems that extend to multiple buildings. We also offer efficient ways of removing the heat that is generated by electronics. While we have grown since our operation began in 1992, our focus has remained the same…providing equipment to support and maintain conditioned space on a 24-hour basis with no down time. We have built our reputation on service, both before and after the sale. Our customers include a who’s who in the manufacturing, banking, healthcare, transportation, retail, telecom and data processing industries. The extensive inventory we maintain and our investment in service support staff demonstrates our dedication to keeping our customers on-line. Our in-house technical service and support staff is factory-trained in all aspects of the equipment we represent. We have in stock availability of over $250,000.00 worth of replacement parts for Liebert Systems alone. Our staff has grown over the years, and so has the number of manufacturers we represent, but we are still focused on you, the customer, and providing 24 hour support. Our employees’ average years of employment with ESS are over 12 and they average more than 15 years experience, with some having 30 years in the industry. Louis since 1988, Engineers Club of St. Louis since 1988, Ashrae since 1993, and Afcom since 2004. We are located in a 10,000 sq. facility in Northwest St. Louis County. Our territory includes eastern Missouri and southern Illinois. We have recently expanded our demo room to be able to demonstrate to our potential customers some of the products we represent, and to highlight some of the latest changes in technology. These new technologies include more efficient and powerful UPS systems, digitally controlled cooling, variable speed air circulation, local and remote monitoring, and management reporting. ESS has received many annual awards for achieving sales quotas from multiple manufacturers.We received Liebert’s Eagle award in 1999 for exceeding sales of $25 million and were honored again in 2007 for exceeding sales of $100 Million and in 2015 exceeding $250 million.

Most organizations deploying AI on-premises hit the same wall. Not the compute, the infrastructure.

Power infrastructure that cannot support AI density. Facilities without liquid cooling. Procurement cycles that add months before a single GPU goes live.

Vertiv™ SmartIT is a pre-integrated, pre-validated rack-level AI infrastructure solution. Power, cooling, compute, and monitoring — we package all of it into a three-rack footprint that fits the space you already have. Ordered as one solution. Delivered as one unit. Commissioned by Vertiv lifecycle services without multi-vendor coordination on your end.

No facility redesign call for. No complex partner management. AI infrastructure built to run when it arrives.

The question now is how fast you want to move.

As you evaluate liquid cooling to support workloads with increasing power demands, the focus often shifts quickly to the technology itself. But successful deployment starts with infrastructure fundamentals.

CEU 337, a continuing education session, explores the foundational elements of liquid cooling infrastructure, including how equipment support, warranty coverage, and ongoing service contribute to long-term operational performance.

The session also examines the role of service in helping sustain critical infrastructure and the IT loads it supports as cooling strategies evolve.

Deploy high-density AI data center infrastructure up to ~85% faster.

Traditional builds slow deployment with multiple vendors, sequential installation, and heavy on-site coordination.

Vertiv™ SmartRun brings power, cooling, and IT infrastructure together in a pre-integrated, manufactured system assembled and tested before delivery. The result is less on-site work, more consistent ex*****on, and faster time to capacity.

Request a consultation to evaluate how Vertiv™ SmartRun can support your next AI infrastructure deployment.

Vertiv announced the acquisition of Strategic Thermal Labs LLC, to strengthen our engineering capability at the interface between server‑side liquid cooling and supporting infrastructure — an increasingly critical factor in high‑density, AI‑driven data center environments.

As AI and high‑performance computing deployments accelerate, system‑level performance and reliability are increasingly shaped by how cold plates, flow dynamics, controls behavior, and serviceability interact across the thermal and power chains. Bringing this specialized expertise in‑house is expected to help Vertiv better simulate and emulate real high‑density compute conditions, optimize system interaction, and improve reliability and lifecycle outcomes across liquid‑cooled environments.

The acquisition reinforces Vertiv’s thermal‑chain strategy while remaining aligned with our commitment to open, interoperable, server‑ and silicon‑agnostic infrastructure ecosystems.

Vertiv announced the acquisition of BMarko Structures LLC, expected to strengthen our ex*****on capacity for manufactured and converged infrastructure.

As AI-driven data center deployments accelerate, customers require faster time to capacity, greater customization, and more control across the infrastructure layer. Bringing structural fabrication capabilities in-house is expected to further enable Vertiv to meet those demands—by expanding engineering and manufacturing capacity, further strengthening supply resilience at scale.

This acquisition vertically integrates a critical capability into Vertiv’s Infrastructure Solutions business in North America, supporting more scalable delivery across our portfolio as infrastructure requirements continue to evolve.
