Cooling technology firm CoolIT has claimed a breakthrough in row-based coolant distribution unit (CDU) performance with a new 2MW product.
The CHx2000 offers 2MW liquid cooling capacity, supporting cooling for up to twelve 120kW Nvidia GB200 NVL72 racks. It does this within a CDU footprint of 750x1200mm.
Canadian vendor CoolIT says the new CDU provides 66 percent greater cooling capacity than its previous leading product, the CHx1500. It claims benchmarking shows the unit offers a 2x cooling capacity bump on the next best '1350' CDU on the market, as well as 53 psi secondary head pressure it says is 'unmatched' in other products.
“We took the already outstanding performance of the CHx1500 and pushed pump performance and heat exchanger capacity even further,” said Neil Mulji, vice president of product at CoolIT. “While both units are in the same compact 750mm x 1200mm rack footprint, we engineered the even higher performance CHx2000 to give customers several performance options.”
Founded in 2001, CoolIT designs, engineers, and manufactures advanced liquid cooling solutions for the data center and desktop markets, including its split-flow direct liquid cooling technology. The company was acquired by KKR and Mubadala in 2023
The company has been experimenting with advanced cooling technologies, and in March debuted a new prototype 4MW liquid cooling coldplate it claims can cool chips more than three times more powerful than the current generation of Nvidia GPUs.
