Case Study: Paraguay

Amid a rapid rise in demand for high-density computing and increasing global pressure to develop sustainable digital infrastructure, data center operators seek solutions that provide exceptional performance, scalability, and environmental sustainability. A key challenge in this segment is delivering extreme rack densities without compromising uptime or consuming additional water resources, especially in hot climates.

One such project was delivered in Paraguay, where a 30MW data center designed for cryptocurrency workloads and future AI clusters was developed. DCX supported the operator by delivering a complete hydro liquid cooling system in an end-to-end deployment, enabling continuous high-density performance with zero water consumption. This project transformed the facility into one of the world’s first large-scale Net-Zero, AI-ready liquid-cooled data centers.

DCX Solution

The DCX team engineered a high-efficiency, fully sealed liquid cooling infrastructure. The system includes 12 closed-loop cooling circuits, each supporting 11 racks with space for up to 22 specialized servers per rack, engineered to operate continuously at extreme density levels exceeding 200 kW per rack. The entire cooling infrastructure was designed to maintain stable thermal conditions under full load, ensuring consistent inlet temperatures and preventing thermal throttling even during peak ambient conditions.

The system covers roughly 1,764 m² of data hall space, with all cooling components integrated smoothly into the existing building layout. DCX designed and installed dedicated manifold assemblies within each rack, ensuring uniform coolant distribution and steady flow to every server. Supply and return piping were installed above the floor for easier maintenance access and hygiene control. In contrast, main return lines outside the facility were routed on elevated supports to enhance security and serviceability.

Heat rejection is managed by high-performance dry coolers located directly next to the building, with a combined capacity of about 2.5 MW at a 35°C ambient temperature. This dry-cooler setup removes the need for evaporative or water-consuming systems, supporting fully water-free operation in a subtropical climate. The entire system runs on demineralized water in a sealed loop, protecting component longevity and maintaining strict media purity standards.

Results:

• Stable operation of a 30 MW infrastructure in tropical environmental conditions.
• 200 kW per rack with no thermal throttling under continuous full-load operation.
• 90% heat extraction efficiency with minimal temperature delta.
• Zero-water-use system, no process water consumption.
• Even coolant distribution across the entire facility, using a Tichelman loop architecture.
• Maximum serviceability and uptime ensured by above-floor piping routes.
