LITEON takes 25% stake in DCX

LITEON is investing approximately $176 million for a roughly 25% stake in Warsaw-based DCX Polska, giving the electronics group a sizeable minority position in a specialist supplier of liquid-cooling infrastructure for high-density data centres.

The transaction, announced on 3 September, brings together two increasingly connected parts of AI infrastructure: moving large volumes of electrical power into racks and moving the resulting heat back out. DCX develops coolant distribution units, facility distribution units, cold plates, immersion-cooling systems, and associated thermal infrastructure, while LITEON is expanding its work around server power management, rack-level power distribution, and 800VDC architectures.

DCX was founded in Warsaw in 2019 and has concentrated on liquid-cooling equipment for data centre and high-performance computing environments. LITEON said the company’s enterprise coolant distribution units span capacities from 600kW to 2.6MW, while facility distribution units aimed at hyperscale environments can extend substantially further. Those are not simply rack accessories: at the upper end, cooling distribution becomes part of the mechanical plant serving an entire data hall.

The two businesses plan to work together on product development, engineering, manufacturing scale-up, and global sales. LITEON is not buying DCX outright, leaving the Polish company as a distinct business while giving the investor direct exposure to an area in which server density is pushing cooling decisions further upstream into facility design.

The underlying engineering shift is already visible in the specification of new AI infrastructure. Conventional air cooling remains suitable for large parts of the installed estate, but processors drawing several hundred watts each and racks designed around much greater compute density can create heat loads that are difficult to manage efficiently with air alone. Liquid systems move heat closer to its source, but introduce a different set of plant requirements around coolant distribution, heat exchange, controls, redundancy, maintenance, and integration with the building’s wider thermal system.

That makes the relationship between power and cooling less separable than it was in lower-density facilities. An 800VDC rack architecture is intended to reduce conversion stages and distribute large amounts of electrical power more efficiently, but higher delivered rack power also increases the thermal load that has to be removed. Designing one side without the other simply moves the bottleneck.

For DCX, LITEON’s manufacturing scale and customer reach could provide a route into larger deployments as liquid cooling moves from specialist high-performance computing rooms towards broader AI capacity. LITEON, meanwhile, gains access to thermal equipment rather than relying solely on the electrical side of the rack.

The investment also puts a Polish engineering business inside a supply chain that is becoming more strategically important as European data centre developers plan higher-density facilities. Much of the discussion around AI capacity is framed around GPUs and power connections, yet the practical limit is set by the complete system: grid capacity, transformers, switchgear, rack distribution, cooling loops, heat rejection, water strategy, and controls all have to arrive in the right sequence.

The transaction remains a minority investment rather than a full integration, so execution will depend on how closely the businesses can align their engineering road maps and manufacturing programmes. If the partnership develops as planned, the combination gives LITEON a more direct position in both sides of the rack-density equation — the power entering the compute environment and the heat leaving it.
