How Glycol Concentrations Can Make or Break Liquid-Cooled Technology Cooling Systems

Read this whitepaper for an overview of the effects of suboptimal propylene glycol concentrations, and recommendations for coolant health monitoring.

Technology Cooling Systems (TCS), employing direct to chip liquid cooling rely on a defined range of propylene glycol concentrations to protect sensitive infrastructure. For data center operators, the risk is subtle but real, and the challenge is that there are no “fill-and-forget” coolants.
