Liquid Cooling Article Series – Part 3
This section examines the XDU070 liquid-to-air Coolant Distribution Unit in terms of its operating principle, cooling capacity, redundant system architecture and data center integration.
In this article, we will take a detailed look at a specialized solution developed for hybrid liquid cooling systems. Below, you can find comprehensive information about the XDU070 liquid-to-air Coolant Distribution Unit, which can be used for high-density data center cooling applications with capacities of up to 100 kW without requiring a free cooling chiller.
What Is the XDU070?
The XDU070 is an innovative liquid cooling solution designed as a liquid-to-air Coolant Distribution Unit. While optimizing cooling operations, the system completely eliminates the need for a free cooling chiller.
Key Benefits
- No additional chilled-water supply is required.
- Installation is straightforward, with minimal infrastructure requirements.
- VSD motors and EC fans support maximum energy efficiency.
Key Features of the XDU070
1. No Free Cooling Chiller Required
The system only requires the XDU070 unit to be installed and the piping connections to be completed. No additional chilled-water source is required.
2. Liquid Cooling with Heat Rejection to Air
The system performs the cooling process through its internal liquid circuit and redundant pumps. The resulting heat is discharged into the surrounding environment through the rear of the unit.
3. Liquid-to-Air Technology
The XDU070 uses the advantages of liquid cooling while rejecting heat to air. This makes it compatible with conventional air-cooling systems while providing a hybrid cooling approach.
4. High Cooling Capacity
It provides a nominal cooling capacity of 70 kW and supports efficient cooling for heat loads of up to 100 kW.
5. Redundant Architecture for Critical Continuity
The system includes redundant pumps, allowing cooling operation to continue without interruption.
6. Intelligent Cooling Management
The unit automatically adjusts its operation according to the heat load, providing cooling based on actual demand.
7. User-Friendly 7-Inch Touchscreen
The touchscreen provides detailed system monitoring through graphical and numerical data.
8. Remote Monitoring and Control Options
Remote access is available through Modbus RTU or TCP/IP communication.
9. Alarm and Notification System
The system generates alarms and notifications in the event of a potential fault.
10. Easy Service and Maintenance
Front or rear access enables faster servicing and maintenance.
11. Hot-Swappable Fans, Pumps and Filters
Fans, pumps and filters can be replaced during operation, supporting continuous system availability.
12. Multi-Unit Configuration and Redundancy Options
Teamwork and redundancy options enable multiple XDU070 units to operate together. This supports load sharing and operational continuity in larger-scale installations.
