In-row coolant distribution unit (CDU) for data center liquid cooling, with 300 kW and 600 kW models, single- or dual-pump options and documented operating conditions.
| Model | Rated heat-exchange capacity | Rated flow | Pump configuration | Dimensions (W × D × H) |
|---|---|---|---|---|
| CDU-300LL3S | 300 kW | 470 L/min | Single pump | 600 × 1200 × 2200 mm |
| CDU-600LL3S | 600 kW | 860 L/min | Single pump | 600 × 1400 × 2200 mm |
| CDU-300LL3D | 300 kW | 470 L/min | Dual pump | 600 × 1200 × 2200 mm |
| CDU-600LL3D | 600 kW | 860 L/min | Dual pump | 900 × 1400 × 2200 mm |
Documented conditions: primary 35 / 45°C; secondary 40 / 50°C; primary fluid: softened water, PG25 aqueous solution or EG25 aqueous solution; secondary fluid: PG25 aqueous solution or EG25 aqueous solution; two-way three-phase AC380–415 V, 50 Hz.
An in-row CDU (coolant distribution unit), also called a row-level CDU, is installed beside server cabinets to transfer heat between the primary and secondary liquid loops through a plate heat exchanger. This liquid-to-liquid series includes 300 kW and 600 kW configurations.
For an in row CDU equipment enquiry, compare the four models in the table below by rated heat-exchange capacity, flow, pump configuration and installation dimensions. Confirm the listed operating conditions against your project; the kW rating alone is not sufficient for selection.
Provide primary- and secondary-loop temperatures, coolant type, required flow, piping interfaces, available power and service clearances for a technical review. For other deployment formats, see the coolant distribution unit range.

Cooltechx is a brand integrating R&D, manufacturing, sales, and service. Our staff comes from Fortune 500 companies with more than 20 years of experience in the air-conditioning industry.
Our R&D technical teams can support customization, which means that if you have different requirements, higher standards, or more functional needs, we will give you the most cost-effective cooling solution.
Cooltechx cabinet air conditioner sample is available, ordering any amount of product is welcomed. The sample is of good quality at a reasonable price.
Through advanced sensing technology and control systems, temperature accuracy of ±0.5°C and humidity control of ±3% RH can be achieved, ensuring optimal operating conditions for data center equipment.
Utilizes high-efficiency components such as variable frequency compressors and EC fans, combined with intelligent control systems that automatically adjust output based on actual load, effectively reducing energy consumption.
Redundancy design and fault warning systems are typically implemented to enhance overall system reliability and availability.
The design considers the year-round cooling needs of data centers, even during winter. Equipment, pipelines, and valves are equipped with effective measures to prevent freezing or cold air from directly entering the main server room, which could lead to condensation and negatively impact electronic information equipment.
The design is simple and easy to maintain, while energy-saving technologies reduce operational costs. For instance, centralized systems have higher maintenance costs, whereas decentralized systems require less than 1 million RMB in annual operating expenses.
For high-density IT cabinets, high heat density solutions are provided to effectively address localized hotspots, including regional high heat density strategies and localized hotspot mitigation methods. instance, centralized systems have higher maintenance costs, whereas decentralized systems require less than 1 million RMB in annual operating expenses.
