Vertiv Agrees to Acquire KES to Expand Liquid-Cooling Services in EMEA
DataNews Editorial Team
Vertiv has entered into an agreement to acquire King Environmental Services Ltd. (KES), a European provider of liquid-system management, commissioning and load-testing services for high-density, liquid-cooled data centers. Vertiv expects the transaction to strengthen its thermal-management service capabilities across Europe, the Middle East and Africa.
- Vertiv has agreed to acquire KES; completion of the transaction has not been confirmed.
- KES provides liquid-system preparation, treatment, commissioning, validation and load-testing services for high-density liquid-cooled data centers.
- Vertiv expects the deal to strengthen its thermal-management services across EMEA.
- The transaction follows Vertiv’s 2025 PurgeRite acquisition in North America and may indicate a wider focus on liquid-cooling lifecycle services.
Vertiv announced on September 24, 2026, that it had entered into an agreement to acquire King Environmental Services Ltd. (KES). The transaction has been announced but has not been confirmed as closed.
KES is a European provider of liquid-system management, commissioning and load-testing services for high-density data centers using liquid cooling. Its scope includes liquid-system preparation, flushing, filtration and water treatment, as well as commissioning and performance validation.
The company also performs thermal load testing for liquid-cooling infrastructure and electrical load testing for critical power systems. Vertiv expects the acquisition to expand its thermal-management service capabilities across EMEA.
For operators deploying liquid cooling for HPC and AI workloads, fluid quality, flow management, commissioning and validation are increasingly material to reliable operation. The deal points to intensifying competition in the service layer of AI data-center infrastructure, where specialist expertise in coolant quality, testing and commissioning may become more strategically valuable alongside the supply of cooling and power equipment.
The proposed KES acquisition follows Vertiv’s 2025 acquisition of PurgeRite, which established a foundation for the company’s liquid-management presence in North America. Together, the transactions suggest a broader effort to build regional service capabilities around liquid-cooled critical infrastructure, although the operational outcome of the KES transaction remains to be demonstrated.
As HPC and AI workloads drive higher rack and facility thermal densities, data-center operators are becoming more dependent on correct fluid preparation, commissioning and operation of liquid-cooling loops. The proposed acquisition signals the growing strategic importance of specialist field and lifecycle services alongside cooling and power equipment; it could also broaden the availability of integrated liquid-cooling lifecycle services in EMEA.
