"CoolIT engineered the CHx1500 to exceed AI and HPC's most demanding cooling roadmap requirements," said Neil Mulji, CoolIT's VP, Product. "What we created in the CHx1500 is not only the powerful row-based CDU unit in the market – providing the best cost per kW – but also a unit packed with all the advanced features and functionality that our OEM and hyperscale customers expect of CoolIT."
Leveraging 24 years of direct liquid cooling (DLC) innovation and developed in close collaboration with leading processor manufacturers and hyperscalers, the CHx1500 delivers 1500kW cooling capacity with a flow rate of up to 1.2 liters per minute per kilowatt (LPM/kW) at 5°C approach temperature difference (ATD).
CoolIT's CHx1500 liquid-to-liquid CDU can cool 9 x NVIDIA GB200 NVL72 racks today, as well as provide ample performance for more thermally dense AI chips and servers in the future.
CoolIT's CHx1500 CDU is not only the most compact but also the highest performer on all key metrics: cooling capacity, flow rates, pressure and density. Compared to similar units from other manufacturers, the CHx1500 provides 27% to 148% greater cooling load, 53% to 463% more cooling load density and 26% to 75% greater pumping pressure.
The following chart shows the nominal performance of the CHx1500 and other CDUs estimated using a 4°C ATD.

For data center operators, the CHx1500 also provides superb serviceability and reliability. The single rack-sized unit is fully front and back serviceable with hot-swappable critical components and multiple levels of redundancy. Control of the unit is available through a 10" touchscreen or remotely through Redfish, SNMP, TCP/IP, Modbus, and several other protocols.
Engineered to strict AI and HPC requirements, the CHx1500's high-reliability design consists of stainless-steel piping, built-in 25-micron filters and highest-grade wetted materials, plus intelligent controls that dynamically regulate the precise temperature, flow and pressure of the coolant to the chip.
The CHx1500 is now available for worldwide orders. CoolIT offers comprehensive support and onsite services in over 75 countries, including system design, installation, CDU-to-server certification and maintenance.
