CDU-RM250
Rack-mount Coolant Distribution Unit

The ATS CDU-RM250 is a high-performance rackmount Coolant Distribution Unit designed to provide up to 235 kW of precise, single-phase liquid cooling for rack-level and modular data center applications. Compact yet powerful, the 4U CDU-RM250 enables efficient liquid-to-liquid heat exchange between facility water loops and IT or electronic cooling loops, delivering exceptional thermal control in a minimal footprint.

Featuring two 48 VDC pumps, PLC-based control, and HMI interface, it offers intelligent operation and full visibility of system performance. Dual redundant pumps and power supplies ensure uninterrupted uptime, while advanced monitoring safeguards against thermal or flow anomalies.

Fabricated from powder-coated aluminum and built for continuous operation, the CDU-RM250 brings enterprise-grade cooling performance directly to the rack.
Features & Benefits
  • Compact Power: 4U rack-mount design delivering up to 235 kW of liquid cooling with 150 LPM facility flow rate at an approach of temperature of 9°C.
  • High Efficiency:Liquid-to-liquid heat exchanger for stable, low-loss thermal transfer.
  • Smart Control:PLC + HMI provide intelligent management and real-time visibility.
  • Reliable Operation:Dual redundant pumps and power supplies ensure uninterrupted cooling.
  
  • Flexible Integration:Designed for seamless connection to facility water loops.
  • Quiet and Efficient:Low-noise, variable-speed pump minimizes energy use.
