The acquisition of the Ireland-based firm serves as a direct expansion of Vertiv’s thermal services, mirroring its 2025 purchase of North American provider PurgeRite. By integrating KES, Vertiv gains regional expertise in fluid-system preparation, filtration, and water treatment—processes essential for preventing corrosion and flow imbalances in liquid-cooled data centers.

Vertiv CEO Gio Albertazzi emphasized that high-density computing requires rigorous field execution to ensure infrastructure longevity. KES, which operates from hubs in Dublin and Frankfurt, provides the necessary validation for high-performance systems before they go live. The move allows Vertiv to offer a consolidated service platform across the EMEA region, addressing the critical need for clean, balanced cooling loops in environments where heat density continues to rise.
