# CoolIT Unveils CHx2000 CDU with 2MW Liquid Cooling Capacity in Standard Rack Footprint
by Harold Fritts on April 17, 2025
[Enterprise](https://www.storagereview.com/enterprise)
CoolIT Systems has announced the launch of the CHx2000, a row-based coolant distribution unit (CDU) that sets a new benchmark for performance in liquid cooling. Following the introduction of the [CHx1500](https://www.storagereview.com/news/coolit-chx1500-delivers-1500kw-of-precision-liquid-cooling) in early March 2025, which redefined industry standards, the CHx2000 elevates performance to an unprecedented level with its 2 MW liquid cooling capacity. This new CDU is currently in production and shipping globally.
## **High-Performance in a Compact Design**
The CHx2000 delivers an industry-leading 2 MW liquid cooling capacity, making it today’s highest-performing row-based CDU. With a flow rate of 1.2 liters per minute per kilowatt (LPM/kW), it can support up to twelve 120kW NVIDIA GB200 NVL72 racks. Despite its exceptional performance, the unit maintains its compact CDU footprint, measuring just 750x1200mm.
Compared to its predecessor, the CHx1500, the CHx2000 provides a 66% increase in cooling capacity. It also surpasses competing solutions, offering more than twice the cooling capacity of the next-best “1350” CDU while maintaining an unmatched 53 psi secondary head pressure. These advancements render the CHx2000 the ideal solution for high-density data centers that require efficient and reliable cooling.
## **Durable and Easy to Maintain**
CoolIT Systems has developed the CHx2000, emphasizing durability, uptime, and ease of maintenance. This unit incorporates high-grade wetted materials, stainless-steel piping, and integrated 25-micron filtration to ensure long-term reliability. The design allows for front and back service access, hot-swappable pumps, filters, and sensors, making the CHx2000 highly serviceable and minimizing downtime during maintenance.

| Company | Product | Cooling Load | Footprint | Cooling Load Density | Secondary Pressure Head |
| --- | --- | --- | --- | --- | --- |
| CoolIT | CHx2000 | 2269 kW | 750 mm x 1200 mm | 2521 kW/m2 | 53 psi |
| CoolIT | CHx1500 | 1364 kW | 750 mm x 1200 mm | 1516 kW/m2 | 44 psi |
| A | “1350” | 1073 kW | 900 mm x 1200 mm | 994 kW/m2 | 25 psi |
| B | “60” | 734 kW | 1222 mm x 1600 mm | 376 kW/m2 | 32 psi |
The CHx2000 is engineered to meet the most demanding performance and availability standards. Built-in redundancies for critical components and advanced group control functionality for up to 20 units enable six-nines (99.9999%) of availability. Intelligent controls provide secure remote monitoring and communication through various protocols, including Redfish, SNMP, TCP/IP, and Modbus, ensuring seamless integration into modern data center environments.

Neil Mulji, Vice President of Product at CoolIT Systems, highlighted the company’s commitment to innovation: “We took the already outstanding performance of the CHx1500 and pushed pump performance and heat exchanger capacity even further. While both units share the same compact 750mm x 1200mm rack footprint, we engineered the CHx2000 to give customers several performance options.”
## **Global Support and Availability**
The CHx2000 is now available for global orders, with CoolIT Systems providing comprehensive support and services in more than 70 countries. These services include system design, installation, CDU-to-server certification, and ongoing maintenance, ensuring customers receive complete support for their liquid cooling needs.
With its unmatched performance, compact design, and strong serviceability, the CHx2000 marks a significant advancement in liquid cooling technology. CoolIT Systems remains at the forefront of the industry by providing innovative solutions that address the evolving needs of high-performance computing and data center environments.
Anyone who attended this week’s Data Center World in Washington, DC, found themselves amid liquid-cooling innovation. As the event progressed, it was clear that CoolIT and its peers are not just shaping the future of data center cooling—they’re redefining what’s possible. With groundbreaking solutions on display, Data Center World proved that the next wave of efficiency and sustainability is already here.
