2.5MW Coolant Distribution Unit (CDU) – Skid Mounted Liquid Cooling Unit
Jiangsu Qianwa 2.5MW CDU is a centralized skid-mounted coolant distribution unit, the core hydraulic & heat exchange hub for high-density AI data centers, GPU training clusters and HPC facilities. It separates facility chilled water (primary loop) and IT coolant (secondary loop) via plate heat exchanger, delivering stable, contaminant-free coolant to cold plate liquid cooling servers. Factory pre-assembled and pressure-tested, this all-in-one skid unit minimizes on-site installation work.
- Rated cooling capacity: 2.5MW, integrated black frame skid structure as shown in photo
- Liquid-to-liquid stainless steel plate heat exchanger, full physical isolation between primary and secondary loops, prevent facility water leakage into IT racks
- N+1 redundant variable frequency pump set, automatic failover, dynamic flow regulation to cut auxiliary power consumption
- Integrated deionizing resin tank + multi-parameter water quality sensors (conductivity, pH, ORP, turbidity) to maintain low conductivity and protect GPU chips
- PLC + local HMI touchscreen, Modbus TCP communication, compatible with BMS / data center monitoring system
- Multi-layer safety interlock: leak detection, over-temperature, high/low pressure, low liquid level alarm & protection

Q: What is a CDU in liquid cooling data center? A: CDU (Coolant Distribution Unit) acts as the heart of liquid cooling system. It transfers heat between facility water and IT secondary coolant, controls flow, temperature and water quality for cold plate servers.
Q: What is 2.5MW CDU used for? A: 2.5MW CDU serves high-density AI GPU clusters and AIDC, delivering enough cooling capacity for a whole computing module with cold plate liquid cooling.
Q: Is skid mounted CDU easier for data center deployment? A: Yes. Skid-type CDU is fully assembled and pressure tested in factory. On-site work only needs pipe, power and communication connection, saving much site labor and time.
