A highly integrated liquid-to-air cooling rack eliminating the need for external facility water loops via primary-side air heat exchange.
Liquid-to-Air (L2A) CDU
- Introduction
- Specifically designed for specialized cooling requirements, the Liquid-to-Air (L2A) CDU is available in multiple rack specifications ranging from 25kW to 125kW. The system utilizes 25wt% Propylene Glycol (PG) as the secondary coolant. Featuring an N+1 pump architecture and 2N+1 power redundancy, it operates with exceptionally low noise and high energy efficiency (mPUE 1.0–1.1), delivering stable and reliable liquid-to-air heat exchange.

High Efficiency & Low Noise: All models operate at noise levels below 85 dB while achieving an outstanding mPUE of 1.0 to 1.1.
High Stability & Redundancy: Features a built-in N+1 pump architecture and 2N+1 power redundancy design, ensuring uninterrupted cooling and heat conversion operations.
Versatile Capacity Options: Available in 25kW, 100kW, and 125kW cooling capacities, corresponding to 20U, 42U, and 48U rack sizes, catering to diverse spatial requirements across various facilities.
Secondary Coolant: 25wt% Propylene Glycol (PG).
Operating Temperature: Ambient temperature: 0°C to 35°C; Secondary coolant temperature: 35°C to 70°C.
Power Input: 1P 220VAC, 50/60Hz; equipped with 2N+1 power redundancy.
System & Communication: Includes 1x RJ45 Ethernet and 4x M12 interfaces for external leak and liquid level detection. Supports HMI, SNMP, and Modbus communication protocols.
Seamless Liquid Cooling Upgrade for Legacy Data Centers: Enables the seamless deployment of high-density liquid-cooled servers in existing air-cooled data centers without requiring major facility modifications or primary chilled water piping. Heat is converted to hot air via the L2A CDU and then processed by the facility's existing Computer Room Air Conditioning (CRAC) units.
Edge Computing & Waterless Infrastructure: Ideal for on-premise enterprise server rooms, edge computing nodes, or telecom data centers lacking large-scale facility water loops. High-efficiency liquid-to-air cooling can be achieved using only standard power supplies.
Rapid Deployment for High-Heat Zones: Provides a flexible, independent liquid-to-air cooling solution for advanced AI nodes generating 25kW to 125kW per rack, effectively eliminating isolated hotspots within the data center.
