Data center cooling and power equipment provider Aggreko has expanded its liquid-cooled load bank (LCLB) fleet by 120MW to meet rising demand from the AI data center sector.

The company said it plans to double this capacity again in 2026, with investments spanning North America, Europe, and Asia.

According to the company, Aggreko’s expanded LCLB fleet supports liquid-to-liquid testing for primary and secondary cooling loops, including chiller systems and coolant distribution units. The equipment also simulates electrical load profiles for integrated systems testing.

The company said the investment allows contractors and operators to commission high-density facilities faster, reduce risk, and meet stricter energy-efficiency requirements.

“The data center market is growing – fast – and with that speed comes the need to adopt energy efficient cooling systems. With this comes challenges that demand innovative testing solutions,” said Billy Durie, global sector head of data centers at Aggreko.

“Our multi-million-pound investment in liquid-cooled load banks enables our partners – including those investing in hyperscale data center delivery – to commission their facilities faster, reduce risks and achieve ambitious energy efficiency goals.”

The company claims that its LCLBs are engineered for mobility and remote operation and are built with corrosion-resistant materials for use in sensitive environments. The company provides full-service commissioning support, offering project-specific testing programs rather than off-the-shelf equipment delivery.

Aggreko said the expanded fleet positions the company to support next-generation AI and HPC data center deployments and comply with regional sustainability and efficiency regulations.

Based in the UK, Aggreko supplies data centers with temporary and permanent power, energy, and temperature-control solutions.
