Vertiv, a leader in data center thermal and power management, is acquiring King Environmental Services (KES), a Europe-based cooling solutions provider, to expand its data center cooling footprint.
Vertiv announced an agreement to acquire King Environmental Services Ltd. (KES), a Europe-based provider of fluid management, commissioning and load-testing services for high-density, liquid-cooled data centers. The acquisition will expand Vertiv's global thermal management services into EMEA and advances its strategy to support customers across the thermal chain. KES brings specialized capabilities in fluid management, commissioning and load-testing spanning system preparation, performance validation, monitoring, maintenance and lifecycle optimization.
The transaction builds on Vertiv's North American fluid management platform, established through its December 2025 acquisition of PurgeRite. By combining KES's regional field expertise and load-testing capabilities with Vertiv's broader services portfolio, the company expects to provide comprehensive support as customers deploy complex AI and high-density infrastructure with greater reliability, efficiency and accountability.
"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," said Gio Albertazzi, CEO of Vertiv. "Our acquisition of PurgeRite established an important fluid management foundation in North America, and KES is expected to build on that foundation in EMEA. Together, these acquisitions advance our strategy to provide the specialized expertise and disciplined execution customers need as they deploy increasingly complex infrastructure at scale."
As high-performance computing and AI workloads intensify heat densities and accelerate liquid-cooling adoption, fluid quality has become critical to uptime, thermal performance and equipment life. Contamination, trapped air, corrosion, improper chemistry and flow imbalances reduce heat-transfer efficiency, contribute to equipment degradation and create commissioning and operational risks. Beyond initial deployment, customers require lifecycle fluid management services to maintain system availability, thermal performance, equipment longevity and operational economics.
KES has built a strong reputation across Europe through technical specialization, experienced field teams, established operating infrastructure and safety culture. Its capabilities include fluid-system preparation, flushing, filtration, water treatment, commissioning and performance validation, as well as thermal load testing for liquid cooling infrastructure and electrical load testing for critical power systems.
Vertiv and KES expect to deliver significant benefits through expanded capabilities designed to reduce operational complexity via a single accountable partner for commissioning, testing, fluid management and ongoing operations; improve cooling system performance with clean, balanced and validated fluid systems; maintain compliance with regional fluid handling, treatment and disposal requirements; and increase confidence in infrastructure readiness through thermal load testing before facilities enter operation.
KES is headquartered near Dublin, Ireland, and serves customers across EMEA. The transaction is expected to close in the fourth quarter of 2026. Financial terms were not disclosed and are not expected to be material to Vertiv's financial results.
