Rear Door Heat Exchanger
(RDHx) Active Flow
High-capacity rack
cooling up to 160 kW.

Efficient and Targeted Rack Cooling

Next Generation Cooling’s rear door heat exchangers are engineered for precise, predictable thermal control in high-density environments. 

NGC’s rear door heat exchangers respond to server load changes in less than 0.5 seconds, ensuring fast and precise thermal regulation.

  • Reduce in energy use up to 90% vs. air-cooled baseline
  • Steady operation rapid thermal response and high reliability
  • Heat reuse potential up to 56°C outlet temperature
  • Full retrofit compatibility installs directly onto existing racks no raised floors
    or special containment required
