ODATA is installing Aligned Data Centers' DeltaFlow liquid cooling at two of its campuses, SP04 in Osasco outside São Paulo and QR03 in Querétaro, Mexico, with installation and testing of a first phase already underway at both sites. The company puts the combined first-phase investment at US$630 million, or 3.2 billion Brazilian reais. It has not broken that figure out between the two campuses, nor said how much of it is the cooling plant itself rather than the wider phase of construction the cooling supports.
The announcement reached the market as a company release, carried in English by Mexico Business News and in Portuguese by DCD's Brazilian edition. Neither version includes pricing, a commissioning date for the first phase, or the rack density the liquid-cooled halls will support. ODATA has not posted the release to its own newsroom, and it did not reach the US wires.
DeltaFlow is Aligned's proprietary, patent-pending liquid cooling system, launched in January 2024 and developed with Munters. It runs as a secondary fluid circuit inside the data hall: a closed loop of deionized water recirculates continuously, so the cooling side consumes no water in operation. That claim is the company's, and a measured water usage effectiveness figure from a running hall would settle it.
The system is built to sit beside Aligned's Delta Cube air cooling, known as Delta³, in the same hall, so air-cooled and liquid-cooled racks can run side by side without a separate AI-dedicated building. ODATA introduced Delta³ across its Latin American sites in October 2024, with SP04 the first Brazilian facility to get it, and it lists both SP04 and QR03 at an average of 50 kW per rack on air. Aligned's claim for the combined platform is 3 to 300 kW per rack. Whether DeltaFlow goes hall-wide at these sites or serves specific tenants is unknown.
Size separates the two campuses. SP04 is a 48 MW IT-load facility on 27,422 square meters of floor area, which ODATA says runs on 100 percent renewable energy from wind farms. QR03 is designed for 300 MW of IT load across as many as five buildings in the PyMe Industrial Park, and ODATA describes it as the largest data center campus in Mexico. Spreading US$630 million across a 48 MW site and a 300 MW site tells a buyer little until the company says which phase of QR03 the money belongs to.
Munters manufactures DeltaFlow units at its plant in Araucária, in the Brazilian state of Paraná, the same facility that builds Delta³ for ODATA. The company says that production complements its US manufacturing and is meant to supply future ODATA projects in Chile and Colombia as well. For a buyer, a domestic factory matters for lead time and import duties on later phases, both of which the release leaves unquantified.
The trade-off is the usual one with a proprietary platform. A tenant taking liquid-cooled capacity at QR03 or SP04 gets a facility engineered for hybrid air and liquid from the outset, but it takes Aligned's cooling architecture rather than specifying its own coolant distribution units and supply temperatures, and Aligned publishes DeltaFlow's thermal limits only in broad terms. The questions to put to ODATA before signing are the supported per-rack density on DeltaFlow at each site, the technology-water supply temperature, and the commissioning date for the first phase.
These are the first DeltaFlow installations ODATA has announced, and they arrive with local manufacturing that shortens the supply chain for every phase after this one. The density, temperature and commissioning figures that would let an engineer size a deployment are not in the announcement, and buyers should treat their absence as the first item on the agenda.
