CoolIT, a leader in AI and high-performance liquid cooling, has introduced the CHx2000, the highest performance row-based Coolant Distribution Unit (CDU).
This follows CoolIT's announcement of the CHx1500 CDU in early March 2025 which set a new standard in performance.
Already in production and shipping globally from CoolIT's multi-gigawatt capacity manufacturing facilities, CHx2000 offers an unrivaled 2 MW liquid cooling capacity.
With a flow rate of 1.2 litres per minute per kilowatt (LPM/kW), it supports cooling for up to 12 120kW NVIDIA GB200 NVL72 racks—all within the industry's most compact CDU footprint of 750x1200mm.
The CHx2000 provides 66% greater cooling capacity than CoolIT's CHx1500 and outperforms alternatives by providing over 2X cooling capacity than the next best "1350" CDU and unmatched 53 psi secondary head pressure.
CHx2000 is built with high-grade wetted materials, stainless steel piping and integrated 25-micron filtration.
Engineered to meet the highest standards for performance, uptime and serviceability, CHx2000 features front and back service access with hot-swappable pumps, filters and sensors.
Built-in critical component redundancies and industry-leading group control functionality for up to 20 units enable six-nines (99.9999%) availability. Intelligent controls support secure remote monitoring and communication via Redfish, SNMP, TCP/IP, Modbus, and other protocols.
