Vertiv has agreed to acquire King Environmental Services, extending its fluid management services into Europe, the Middle East and Africa.
King Environmental Services, known as KES, provides fluid management, commissioning and load-testing services for high-density liquid-cooled data centres and other sites. Based near Dublin, it serves customers across EMEA from hubs in North Dublin and Frankfurt.
Vertiv did not disclose financial terms. The transaction is expected to close in the fourth quarter and is not expected to be material to its financial results.
The acquisition adds field services tied to the preparation and operation of liquid-cooled infrastructure as operators deploy denser computing systems. KES's work includes flushing, filtration, water treatment, commissioning and performance validation, along with thermal load testing for liquid-cooling infrastructure and electrical load testing for critical power systems.
Liquid-cooling systems depend on tight control of fluid quality and flow. Contamination, trapped air, corrosion and chemical imbalances can reduce heat transfer and shorten equipment life. Testing and balancing can also determine whether systems perform as designed as facilities move from construction into operation.
The deal also builds on Vertiv's existing presence in this segment in North America following its acquisition of PurgeRite in 2025. By adding KES, Vertiv links that earlier deal with a regional services base in EMEA.
Customers are seeking a single provider for commissioning, testing and ongoing fluid management as data centre systems become more complex. Vertiv also pointed to regional requirements around fluid handling, treatment and disposal as an area where specialist support is needed.
Field work
Founded in 2002, KES focuses on the point where cooling systems move from design and construction into live use. Its services include design review and feasibility studies, pipework flushing, filtration and water treatment, testing, adjusting and balancing, data logging, thermography, and large-scale thermal and electrical load testing.
That mix of services reflects a wider shift in the data centre market, where demand linked to artificial intelligence and high-performance computing is increasing heat density inside facilities. As operators adopt liquid cooling more widely, specialist contractors that can prepare, test and validate these systems have become more central to delivery and operations.
For Vertiv, the transaction broadens a services portfolio that already spans power and thermal systems for digital infrastructure. The company operates in more than 130 countries and sells equipment and services to data centres, communications networks and industrial customers.
Chief Executive Officer Gio Albertazzi said the acquisition is intended to strengthen execution in the field as infrastructure becomes harder to deploy and maintain.
“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, Chief Executive Officer of Vertiv.
He also linked the move to Vertiv's earlier North America deal and its broader services strategy.
“Our acquisition of PurgeRite in December 2025 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 specialised expertise and disciplined execution customers need as they deploy increasingly complex infrastructure at scale,” Albertazzi said.
The purchase gives Vertiv an established operating base in a region where new data centre construction has continued despite tighter power availability and rising scrutiny of infrastructure efficiency. It also adds a specialist team with experience in commissioning and validation work often required before a facility enters service.
KES has built its business around ensuring cooling systems are clean, balanced and ready for high-density computing environments. Its thermal and electrical load-testing work is used to check whether systems can withstand operational demands before live workloads are introduced.
Both companies are positioning the deal around practical site execution rather than product expansion alone, emphasising maintenance, validation and system readiness in liquid-cooled facilities.
