ChemTreat has published a white paper, The Framework for Operational Readiness in Data Center Cooling Systems, aimed at improving day-one reliability in AI data center cooling systems by tightening the handoffs between design, commissioning, and long-term operations.
The paper is targeted at owners, engineers, project teams, and contractors, with a focus on what ChemTreat describes as emerging gaps in AI data center construction and commissioning processes. ChemTreat ties the framework to uptime expectations in high-density facilities, where availability targets can be “five-nines” (99.999%), and it notes that in 2025, most major data center outages cost more than $100,000.
A core technical concern in the paper is cooling-system water readiness. ChemTreat argues that many projects still use outdated water readiness standards and hydronic cleaning specifications, which can allow contaminants into cooling loops prior to startup. In water-based cooling systems, that early contamination can become a corrosion and fouling problem after turnover, when it’s far more expensive to remediate without disrupting operations.
ChemTreat says it reviewed “hundreds” of data center specifications and found that relatively few include meaningful input from cooling system and fluid chemistry experts. The company’s point is straightforward: if cooling-water and chemistry decisions happen late in the build, key choices around water system configuration and chemical treatment integration are already locked in, limiting the ability to define measurable turnover standards and creating reliability risk before the facility is even live.
“The reality is that long-term reliability is often decided before a system ever comes online,” said Jacob Paugh, Senior Director of Global High Tech at ChemTreat. “This framework provides owners, engineers, and contractors with a practical way to get ahead of potential issues, rather than compromising uptime to fix corrosion and contamination after the racks are running.”
ChemTreat’s Operational Readiness Framework is built around five core principles for commissioning, and it includes a Preconstruction Readiness Assessment intended to bring cooling expertise into the project earlier. It also includes a Day-One Readiness Checklist that spans design, construction, commissioning, and governance, with the stated goal of giving project teams measurable criteria to assess cooling-system readiness before AI workloads come online.
“Commissioning has traditionally been treated as a construction milestone, when it should be the foundation for long-term reliability,” said Dr. Philip Yu, Senior Technical Services Consultant at ChemTreat. He added that earlier involvement of cooling-system and fluid-chemistry expertise can help tailor commissioning to “each site’s unique water specifications, discharge, and infrastructure constraints.”
ChemTreat also points to its Blueprint to Beyond program, which it says supports data center cooling systems from preconstruction through steady-state operations, including field engineers, treatment programs, monitoring, and laboratory validation, plus its CTSolutions D2C direct-to-chip cooling package.
