Aligned Launches Delta Cube 3.0 Air Cooling
The upgraded in-house system adds cooling capacity and energy efficiency within the same footprint as earlier versions.
Updated on Nov. 2, 2026 in Data Centers
Aligned Data Centers launched Delta Cube 3.0, a new version of its in-house air cooling system, built in partnership with power and cooling vendor Munters. The company says the system delivers a ten percent increase in cooling capacity and a ten percent boost in energy efficiency within the same physical footprint as previous iterations.
Why it matters
Aligned states that as compute densities rise, air cooling must adapt to ultra-high-density environments. The update targets operators who need more cooling from existing space as data center demand grows.
Delta Cube 3.0 delivers a ten percent increase in cooling capacity and a ten percent efficiency boost within the same footprint as prior versions, and it is a closed-loop system that requires zero water for operational cooling. The performance figures are manufacturer-reported, and independent testing results were not provided.
The players
Aligned Data Centers
Aligned Data Centers is a data center developer and operator that built Delta Cube 3.0 and owns the Brazilian platform Odata.
Munters
Munters is a power and cooling vendor that partnered with Aligned to build Delta Cube 3.0 and manufactures the cooling units in the United States.
The details
Aligned made enhancements to its proprietary heat exchangers, supply fan impellers, and drive motors to achieve the gains, with Munters' R&D team working alongside Aligned to develop the cooling units. The Delta Cube cooling units will be manufactured in the US at Munters facilities in Selma, Texas, and Daleville, Virginia.
Timeline
January 2024: Aligned launched its DeltaFlow liquid cooling system.
2024: Odata, a Brazilian data center platform owned by Aligned, announced it would begin using Delta Cube.
July: Aligned was acquired by a consortium of MGX, AIP, and BlackRock for $40 billion.
November 2, 2026: Aligned launched Delta Cube 3.0.
Under the Hood
Delta Cube 3.0 extends Aligned's cooling lineup alongside its DeltaFlow liquid cooling system introduced in January 2024, showing the company pursuing both air and liquid approaches as rack densities climb. The air-based update aims to extend what conventional air cooling can handle in ultra-high-density facilities.
For operators and developers, Delta Cube 3.0 offers a way to raise cooling capacity and efficiency without expanding physical footprint or using water for operational cooling. The gains are manufacturer-reported, so buyers would need to evaluate them against their own deployment conditions.
The takeaway
Facilities facing higher rack densities can consider whether air cooling upgrades that keep footprint and water use constant fit their expansion plans. Evaluating manufacturer efficiency claims against independent data before committing to a system is a practical step.
