Higher-density computing is changing the role of cooling infrastructure, with direct-to-chip systems introducing new considerations around fluid selection, chemical management and long-term system reliability. A coolant that appears suitable on paper can create challenges further down the line, from corrosion and inhibitor depletion to fouling, contamination and degraded thermal performance.

This Dow whitepaper breaks down the 6+1 questions data center operators should ask when selecting a PG25 coolant and supplier, covering inhibitor chemistry, fluid purity, service life, supply security, technical support and ongoing fluid management. It looks beyond the initial specification to examine the factors that can influence the reliability and performance of a technical cooling loop throughout its lifecycle.
