Coolant Distribution Unit 
Intelligent flow control and system integration for rack-level cooling 

Coolant Distribution Unit (CDU)

NGC’s Coolant Distribution Units connect rack level cooling to facility infrastructure through a modular, hydraulically steady design. Each CDU ensures defined operating conditions, precise flow regulation, and predictable thermal performance across the system. 

NGC’s Coolant Distribution Units are available in two defined capacity platforms: 

  • Active rack-levelCDUssupporting 10– 50 kW deployments
  • Passive system-level CDUs supporting 300–500 kW installations 

Each platform operates within clearly specified hydraulic parameters to ensure stable performance and predictable thermal behaviour. The modular platform design enables scalable deployment while maintaining controlled hydraulic conditions. 

Engineered for applications ranging from single-rack installations to multi-megawatt systems. 

  • Defined Hydraulic Control Maintains stable pressure and flow conditions across connected racks. 
  • Rack-Level Independence 
    Reduces hydraulic interaction between units and preserves thermal stability. 
  • Modular Capacity Platforms 
    Available in two defined platforms: 10– 50 kW (active) and 300–500 kW (passive). 
  • Seamless Facility Integration 
    Connects rack-level cooling to primary supply without complex rebalancing.
