Summary
- OData is deploying DeltaFlow at SP04 in Brazil and QR03 in Mexico.
- Installation and testing are under way within a combined $630m first-phase investment programme.
- DeltaFlow will operate with existing Delta³ air cooling, allowing hybrid air-and-liquid environments.
OData is deploying Aligned Data Centers’ DeltaFlow liquid-cooling technology at its SP04 campus in Brazil and QR03 site in Mexico through a combined $630 million first-phase infrastructure programme.
Installation and testing are already under way at both facilities. The $630 million figure covers the wider first-phase investment at the two campuses and should not be read as the cost of the liquid-cooling equipment itself.
DeltaFlow was developed by OData parent Aligned Data Centers with cooling supplier Munters. The system is intended to support dense computing environments while operating alongside Aligned’s Delta³ air-cooling architecture.
That creates a hybrid model in which air-cooled and liquid-cooled workloads can operate within the same data hall or campus.
The approach provides a useful comparator for European operators because established data centres are unlikely to convert every rack to liquid cooling at once. Conventional servers, storage, and network equipment can continue to operate efficiently with air while selected AI clusters require much higher cooling capacity.
Hybrid deployment can therefore avoid replacing mechanical infrastructure unnecessarily. It also creates operational complexity because multiple cooling architectures must coexist within the same resilience and maintenance framework.
Operators have to manage secondary coolant loops, coolant distribution units, heat exchangers, pumps, controls, leak detection, and water chemistry while preserving redundancy across the facility.
OData says DeltaFlow operates as a secondary-fluid loop within the data hall. The company’s facilities use closed-loop cooling arrangements intended to avoid operational water consumption for heat rejection.
That distinction matters in markets where the water footprint of data centres is under increasing scrutiny. A closed loop can continually recirculate coolant, although the full water and energy profile still depends on the wider heat-rejection design and local operating conditions.
Munters is manufacturing DeltaFlow equipment at its Araucária facility in Paraná, complementing production in the US. Local manufacturing is intended to support the Brazilian and Mexican deployments as well as future regional projects.
The supply-chain point is increasingly important as liquid cooling moves from bespoke projects to repeated infrastructure programmes. Coolant distribution units, pumps, heat exchangers, valves, controls, and specialist pipework all have to arrive in step with server and electrical deployment.
The project itself is outside Europe, so it should be read as a delivery comparator rather than a regional capacity story. European brownfield facilities face the same question of how to add dense AI capacity without replacing every existing system.
OData’s rollout provides one model: supplement existing air cooling with dedicated liquid infrastructure, then expand it alongside customer demand. Its installation and testing programme should provide further evidence of how that hybrid architecture performs at multi-campus scale.
