Vertiv is expanding its data-centre thermal management capabilities across Europe, the Middle East and Africa (EMEA) through a planned acquisition of Ireland-based King Environmental Services Ltd. (KES), a specialist in fluid management, commissioning and load testing for high-density and liquid-cooled infrastructure.
Vertiv Holdings Co, the US-based critical digital infrastructure company, announced on October 1 that it had entered into an agreement to acquire KES. The transaction is expected to close in the fourth quarter of 2026, although financial terms were not disclosed.
The proposed acquisition comes as the rapid growth of artificial intelligence and high-performance computing drives higher heat densities in data centres and accelerates the adoption of liquid-cooling technologies.
Unlike conventional air-cooled systems, liquid cooling places greater emphasis on the condition and performance of the fluid circulating through the cooling system. Contamination, corrosion, trapped air, inappropriate water chemistry and flow imbalances can affect heat transfer, damage equipment and create operational risks.
KES will add specialist capabilities covering fluid-system preparation, flushing, filtration, water treatment, commissioning and performance validation to Vertiv’s existing services portfolio. The company also provides thermal load testing for liquid-cooling systems and electrical load testing for critical power infrastructure.
Headquartered near Dublin, KES operates across the EMEA region and has developed field-service capabilities focused on the preparation, testing and ongoing management of cooling and critical infrastructure systems.
For data-centre operators, the significance of such services extends beyond initial installation. As liquid-cooled systems become more common, maintaining fluid quality and verifying system performance throughout the infrastructure lifecycle can become an important part of ensuring thermal efficiency, equipment reliability and availability.
The acquisition is also intended to strengthen Vertiv’s ability to provide integrated services covering commissioning, testing, fluid management and ongoing infrastructure support.
“As computing density increases, the performance of cooling and power infrastructure will depend as much on execution in the field as on engineering and system design,” Vertiv CEO Gio Albertazzi said.
The deal follows Vertiv’s acquisition of North American fluid-management company PurgeRite in December 2025. Vertiv said the two acquisitions are expected to complement each other by giving the company fluid-management capabilities in both North America and EMEA.
The company said combining KES’s regional field expertise and load-testing capabilities with Vertiv’s wider infrastructure and services portfolio should provide customers with a more integrated approach to preparing and operating increasingly complex data-centre environments.
The expansion comes at a time when data-centre operators are reassessing cooling architectures to accommodate AI workloads. Higher-density computing can significantly increase the amount of heat generated within a rack, creating challenges for conventional cooling systems and increasing demand for technologies capable of moving heat more efficiently.
Vertiv said the planned acquisition is expected to help customers reduce the complexity of commissioning and testing, improve cooling-system performance, meet regional requirements for fluid handling and treatment, and validate infrastructure before facilities enter operation.
The transaction is expected to be completed in the fourth quarter of 2026, subject to customary closing conditions. Vertiv said the financial terms were not disclosed and are not expected to be material to its financial results.
