The nVent Liquid-to-Air (LTA) Sidecar Heat Rejection Unit (HRU) is a completely integrated liquid-to-air heat rejection system that enables up to two racks of liquid-cooled IT equipment when a Facility Water System (FWS) is not available.
The LTA Sidecar comes in a 48U rack with footprint of 600mm (24 inches) wide by 1200mm (48 inches) deep.
The LTA Sidecar comes standard with 14 hot-swap fans in N+1 configuration, a reservoir pump unit (RPU) with N+N hot-swap pumps, a hot-swap controller, a hot-swap concurrently maintainable redundant filtration system, 6 x N+N redundant power supplies, integrated leak detection, leak-free hose connections, and an LED Light Path status panel. Active components such as fans, pumps, power supplies, and liquid connections for filling and draining the system are all located on the front side of the Sidecar HRU for easy access.
Support for GB200 NVL36 and GB200 NVL72 rack configurations with a single GB200 NVL36 rack supported by a single Sidecar HRU (1:1) and a single GB200 NVL72 rack supported by two Sidecar HRUs (2:1) in parallel
LTA Sidecar supports GB 200 NVL72 configuration in a 2:1
CONFIGURATIONS WITH THE NVL36 & NVL72
Integrating liquid cooling into existing data centers can be achieved through specific configurations utilizing NVL36 and NVL72 racks. These configurations are designed as reference for the AI Chipsets. Using an LTA sidecar, you deploy AI Chips in existing data centers with minimal infrastructure swap outs.
WHY DEPLOY LIQUID COOLING WITHOUT FACILITY WATER
Deploying liquid cooling without relying on facility water offers significant advantages, such as avoiding the complexities of facility water infrastructure and reducing operational costs. This approach allows data centers to leverage alternative cooling solutions while maintaining high performance and reliability.
