CoolIT says that the CHx1500 sets a new benchmark for row-based CDU performance, offering 1500 kW of cooling capacity at a 5°C approach temperature difference (ATD) — surpassing the capabilities of similar products on the market by a significant margin. ![CoolIT CHx1500](https://www.storagereview.com/wp-content/uploads/2025/03/Storagereview-coolit-liquidcool-1-545x1024.png) ## **CoolIT CHx1500 Performance and Capabilities** The CHx1500’s cooling capacity is supported by a flow rate of 2100 liters per minute (LPM) on the primary side and 1800 LPM on the secondary side, ensuring consistent and efficient heat removal. The unit has two hot-swappable pumps (N+N redundancy) capable of delivering 1500 LPM at a 34 psi pressure drop. This redundancy ensures uninterrupted operation, improving overall system reliability even if one pump fails. Built with all stainless-steel piping and 4-inch Victaulic couplings, the CHx1500 is designed for durability and long-term operation in demanding data center environments. Its single-rack footprint of 750mm wide x 1200mm deep makes it compact enough to fit into existing infrastructure without requiring additional floor space. ## **CoolIT CHx1500 Intelligent Controls and Serviceability** The CHx1500 features an integrated control and monitoring system compatible with multiple protocols, including Redfish, SNMP, TCP/IP, Modbus, and BACnet, allowing for flexible and remote management. It also includes a group control feature that enables coordinated operation of up to 20 units, beneficial for scaling in large data center environments. ![CoolIT CHx1500 prepping]() The unit is equipped with hot-swappable 25-micron filters, with an option for 50-micron filtration, which helps maintain coolant quality and prevent blockages. Integrated fill pumps and a reservoir simplify maintenance and reduce the need for external equipment. An integrated ultracapacitor ensures the system remains operational during brief power interruptions, with an optional automatic transfer switch (ATS) available to enhance power redundancy further. ## **CoolIT CHx1500 Comparative Performance Data** Compared to other row-based CDUs, the CHx1500 delivers between 27% and 148% greater cooling load, 53% to 463% higher cooling load density, and 26% to 75% higher pumping pressure. The table below displays how the CHx1500 stacks up against similar models from other manufacturers: | **Company** | **Product** | **Cooling Load** | **Footprint** | **Cooling Load Density** | **Secondary Pressure Head** | | --- | --- | --- | --- | --- | --- | | **CoolIT** | **CHx1500** | **1364 kW** | **750×1200 mm** | **1,516 kW/m²** | **44 psi** | | A | “1350” | 1073 kW | 900×1200 mm | 994 kW/m² | 25 psi | | B | “60” | 734 kW | 1222×1600 mm | 376 kW/m² | 32 psi | | C | “800” | 678 kW | 811×1216 mm | 688 kW/m² | 35 psi | | D | “1100” | 550 kW | 815×1230 mm | 549 kW/m² | 30 psi | ## **CoolIT CHx1500** **Availability and Support** The CHx1500 is available for worldwide orders. CoolIT provides end-to-end support in over 75 countries, covering system design, installation, CDU-to-server certification, and ongoing maintenance.
