Reverse Ionizer has introduced its Plasma Disinfection System (PDS), a patented technology it says is designed to enable efficient water-based direct-to-chip (DTC) cooling for high-density AI infrastructure. The company positions PDS as a way to improve temperature control while supporting data center energy efficiency and protecting AI chip performance and functionality.

Reverse Ionizer says PDS targets biological fouling in cold plate micro-channels, which it describes as a persistent barrier to using water as a primary coolant in high-density computing environments. The company says the goal is to keep both facility cooling systems and chip-level cooling loops operating efficiently to sustain heat transfer performance as rack power density increases.

“The PDS uses advanced non-thermal plasma discharges to continuously control bacteria growth and biological fouling, eliminating insulating biofilm in cooling systems throughout closed-loop DTC systems to sustain optimal heat transfer efficiency and maintain maximum power capacity per rack—critical factors as chip densities continue to increase,” said Patrick Hughes, CEO of Reverse Ionizer. “It does the same in open-loop chiller/cooling tower systems,” said Patrick Hughes, CEO of Reverse Ionizer. “Compared to glycol-based solutions, water increases heat transfer efficiency by 15% to 20%, allowing designers to reduce pump size requirements while maintaining optimal thermal performance.”

The announcement lands as the company cites broader constraints on AI infrastructure build-outs. Reverse Ionizer points to TheStreet’s reporting that “a looming critical infrastructure obstacle is holding up the AI boom.” It also cites a LinkedIn post from Vertiv Holdings Co. CEO Giordano Albertazzi: “AI workloads are operating at unprecedented complexity and criticality. This demands new levels of data center visibility and insights to operate reliably and efficiently.”
