Do you trust companies to prioritize infrastructure reliability during the rapid expansion of AI technology?
Aggreko has deployed a new fleet of liquid-cooled load banks designed to simulate the high thermal and electrical demands of modern AI data centers. These units are currently available for facility commissioning, offering scalable options for testing cooling infrastructure.
Why it matters
As AI and high-performance computing drive up rack densities, data centers face increased risks of cooling failure during startup. This testing infrastructure provides a controlled way to validate thermal systems before high-value IT equipment is installed.
The units are built with 316L stainless steel and support flexible configurations of 200kW, 300kW, or 600kW per load bank. Systems allow for precise management of total power load, delta T, and leaving water temperatures for benchmarked cooling validation.
The players
Aggreko
A provider of modular power and temperature control solutions specializing in industrial energy management and temporary infrastructure.
The details
Load banks function as artificial IT equipment, mimicking the electrical and thermal loads generated by servers during the initial commissioning phase of a data center. These units are cleaned, flushed, and sealed to ensure the integrity of the cooling loop before operation. By networking multiple units, operators can scale load management to match the projected density of their high-performance computing deployments.

The Tech Race
This hardware fleet represents a move toward specialized commissioning tools required to support the extreme thermal output of current AI and high-performance computing clusters. It marks a shift away from legacy air-cooled testing methods, which struggle to validate the cooling capacity of high-density liquid-cooled server environments.
Data center operators can now integrate these units into their commissioning workflows to identify potential thermal bottlenecks before installing expensive GPU clusters. The units provide immediate utility for European facilities needing to verify liquid cooling performance under high-load conditions.
The takeaway
Data center engineers should prepare for higher site-acceptance testing requirements as liquid-cooled rack densities become the industry standard. Watch for upcoming case studies on how these units perform during large-scale commissioning projects throughout Europe.
