How We Operate
The manufacturing agent model in data center infrastructure has traditionally split along a clean line: one set of firms sells facility-side equipment — chillers, condensers, power distribution — while engineering teams handle compute specification independently. That model worked when racks drew 30 kilowatts of air-cooled compute and the cooling conversation started and ended at the facility wall.
At 100 kilowatts and above, that line disappears. Cooling architecture is now driven by what's inside the rack — which GPU generation, which server OEM, what workload, what density. Facility-side equipment has to be sized and aligned to those decisions, not the other way around.
Critical System Infrastructure operates across both sides of that conversation. We work with MEP firms and general contractors on the cooling loop, chiller sizing, and facility integration. We work with data center operators, neoclouds, and GPU-as-a-service providers on the compute stack, deployment path, and infrastructure timeline. One firm, both audiences, one coherent design conversation.
Our role
Critical System Infrastructure is not the OEM, the thermal engineer, or the MEP. Our role is to identify opportunities early, understand where our technologies are relevant, educate stakeholders, and bring the right manufacturer resources into the conversation.
CSI opens the door, frames the opportunity, and moves the deal.

Leadership
Charles J. Bachmann
Founder & Principal
Charles brings two decades of enterprise technology and data center sales leadership to Critical System Infrastructure. His career spans cloud and colocation services, data management and industrial IoT software, and most recently the go-to-market build-out for two-phase direct-to-chip liquid cooling — where he developed partner ecosystems spanning MEP engineering firms, manufacturer representatives, and modular builders, and supported reference architecture work across powered land sites and high-density deployments.
He founded Critical System Infrastructure to work the full infrastructure conversation: aligning the engineering teams designing next-generation facilities with the manufacturers building the cooling and critical power technologies those facilities depend on. He holds an MBA from Carthage College and a business degree from Loyola University Chicago.
Critical System Infrastructure is a DBA of CJBE LLC, an Illinois limited liability company.
