Air-Liquid CDU vs Liquid-Liquid CDU Key Liquid Cooling Solutions for Data Centers

30kW vs 50kW+: Choosing Between Transitional Air-Liquid and Full-Coolant Liquid-Liquid CDUs

Liquid cooling systems split into two mainstream CDU routes. Air-liquid CDUs combine liquid cooling inside cabinets with air-based heat rejection, making them a cost-effective transitional choice for legacy facility upgrades and mid-low power density rooms up to 30kW. Liquid-liquid CDUs transfer heat entirely through coolant, delivering stronger efficiency, ultra-low PUE and support for racks above 50kW—ideal for high-density GPU server and containerized cooling, despite higher initial investment. Rising server power density is driving demand. EXTRCOOL offers dual-mode CDUs, manifolds, cold plates, rear-door heat exchangers, dry coolers and containerized systems for high-density AI and HPC data centers.
