Further Details

To expand AI services, the client collaborated with a global GPU manufacturer and introduced GPU-as-a-Service. Traditional CPU racks run at 5–10 kW, but GPU clusters reached 20–50 kW per rack, creating extreme heat. They needed reliable cooling to maintain performance without infrastructure overhauls.

The client deployed 192 ColdLogik CL20 RDHx units:

• 138 units of 4U, cooling capacity 50 kW
• 24 units of 4U, cooling capacity 30 kW
• 30 units of 4U, cooling capacity 20 kW

Air-assisted liquid cooling absorbs and expels heat, releasing air near 22 °C with chilled water at 15 °C. ColdLogik adaptive controllers regulate fan speeds and monitor temperatures for consistent performance and energy efficiency.

Complete deployment—including racks, RDHx units, and wiremesh cable trays—was finished in just 45 days, including testing and integration by Legrand Certified Service Partners.

• PUE of 1.35, classifying the facility as energy-efficient
• Racks run 40 kW loads with N+1 cooling, scalable to 59 kW
• Reduced cooling footprint—no extra ducting or airflow systems
• Minimized hot spots and airflow issues, lowering maintenance costs
• Delivered a flexible, future-ready cooling solution with simplified installation and operations

Timeline: 3 months total (supply and implementation).
Client: A leading Indian data center infrastructure provider offering colocation, cloud hosting, network & connectivity, IT security, and infrastructure management.
