US AI Infrastructure Firm Crusoe Debuts 3.5 MW Liquid-Cooled Modular Data Center Unit to Bypass Grid Delays
Crusoe launches the sixth-generation Spark Liquid modular data center, supporting 3.5 MW per unit and optimized for Nvidia's latest racks, aiming to accelerate AI compute deployment through factory-built solutions.
US-based AI infrastructure company Crusoe debuted its new Spark Liquid modular data center unit on November 4, 2026. The unit is designed to support up to 3.5 megawatts (MW) of compute capacity per module and is built specifically for Nvidia GB300 NVL72 and Vera Rubin NVL72 racks. Crusoe stated that this platform will join its existing production line in Brighton, Colorado, with manufacturing scheduled to begin in 2027.
Unlike traditional on-site construction, Spark Liquid utilizes a closed-loop direct liquid cooling (DLC) system to manage heat from high-density GPU clusters. Bryan Schramm, Head of Spark at Crusoe, noted that as rack power continues to rise, air cooling can no longer remove sufficient heat, making DLC necessary. The system recirculates water in a closed loop, minimizing ongoing water usage and eliminating evaporative loss. Schramm emphasized that this factory-built approach addresses three key constraints facing AI infrastructure: power availability, predictability, and "time to token."
Regarding power, large grid interconnections often take years to secure, whereas modular units can leverage available distributed power sources such as on-site generation, small modular reactors, or solar paired with batteries. This allows for faster connection to demand centers. In terms of predictability, factory environments offer more reliable delivery dates compared to construction sites, which is critical for organizations reserving capacity in advance. Additionally, modular infrastructure significantly shortens the time from build to revenue, with Schramm stating that capacity can come online in as little as a few months from a ready site.
Crusoe also announced that its Spark platform will support Nvidia's recently released DSX POD standard, a blueprint for modular infrastructure designed for the Vera Rubin platform. Nvidia designs and validates the reference architecture, while partners manufacture and integrate the units. Crusoe is one of eight container solution providers listed by Nvidia. While specific performance metrics are vendor-reported, this move reflects the industry's shift toward vertical integration and standardized modules to overcome physical and regulatory bottlenecks.
