Crusoe Unveils Spark Liquid Modular Data Center for Nvidia's Latest GPUs

Neocloud provider Crusoe has developed a liquid-cooled iteration of its modular data center product line, Crusoe Spark, marking a significant step forward in compute density for prefabricated infrastructure. The launch comes as demand for AI-capable data center capacity continues to outstrip supply, pushing operators to seek faster, more flexible deployment models that can accommodate the latest generation of high-power GPUs.

The new Spark Liquid system supports up to 3.5MW of compute per unit, a five-fold increase over the 500kW IT capacity of the existing air-cooled Spark version. Co-founder and President Cully Cavness told DCD that multiple units can be deployed together to reach capacities of up to 100MW, with production expected to begin next year at the company's existing factory in Brighton, Colorado. Each Spark consists of three shipping-container-sized modules snapped together, forming a footprint of roughly 60 feet by 50 feet. The system uses closed-loop cooling, consuming no additional water beyond the initial filling phase.

The product is currently aimed squarely at Nvidia's latest hardware, supporting GB300 NVL72 and Vera Rubin NVL72 racks, with all Spark Liquid units produced in 2027 expected to use Nvidia equipment. Cavness noted that Spark Liquid is one of the first designs compliant with Nvidia's DSX Modular reference architecture, and that the platform has achieved what Nvidia calls Exemplar status for cloud reliability. "They've done a bunch of testing on the way we interconnect different Sparks, and they've said that B300s perform in that deployment to the same level of speed and reliability as they do in a large stick-built traditional data center," Cavness said.

Despite the comparable performance, Crusoe still expects to rely on traditional construction for larger-scale builds. "Ultimately, if you're going to go train a frontier model, we think still the large interconnected campus, like our flagship project in Abilene, probably makes sense if you're going toward gigawatt scale," Cavness said, adding that Spark is primarily targeting deployments of 10MW and above, with 20-50MW representing the sweet spot. All modular liquid deployments planned for next year are currently earmarked for Crusoe Cloud, the company's cloud platform. Erwan Menard, SVP of product, said customers increasingly reserve capacity ahead of deployment given current supply-demand dynamics, and that the modular approach could serve latency-sensitive workloads such as physical AI and sovereign deployments requiring dedicated, resilient compute regions.

Crusoe's vertical integration strategy extends to manufacturing its own switchgear at a factory in Tulsa, Oklahoma, where the company performs all sheet metal work and produces switchgear boards including low-voltage and medium-voltage components. This approach helps mitigate some supply chain constraints, though Cavness acknowledged that long lead times for chillers, CDUs, and transformers remain industry-wide challenges. Menard also expressed optimism that the smaller modular format could reduce local opposition compared with megaprojects, noting that a 20-40MW site with comparable per-megawatt economics can bring tax revenue to communities while allowing operators to dial energy consumption and avoid water use entirely.
