Engineered for Reliable, Predictable Performance

NGC cooling systems are designed to operate within clearly defined thermal and hydraulic parameters ensuring steady performance across the full operating range.

Our Rear Door Heat Exchangers remove heat directly at the rack using elevated supply temperatures and self-regulated flow, maintaining thermal neutrality at room level.

NGC’s CDU connect rack-level cooling to facility infrastructure in scalable configurations from single racks to multi-megawatt installations enabling precise calculation of flow rates, return temperatures, and system-wide performance.

Designed for Simplicity

NGC’s cooling architecture is built around a modular flow structure that simplifies integration, scaling, and operation in high-density data-centres

  • Clear separation between rack-level cooling and facility infrastructure
  • Modular design that adapts to deployment scale
  • Direct integration with existing building systems
  • Closed-loop operation for predictable thermal behaviour

Each rear-door unit operates with its own high-efficiency Grundfos pump, ensuring that flow is regulated directly at rack level rather than through extended distribution paths.

This reduces hydraulic interaction between racks and increases system stability under dynamic load conditions.

The CDU connects rack-level cooling to the facility’s cooling source and distributes fluid across multiple doors – preserving system independence.

Because each rack regulates its own flow, capacity can be added or adjusted without redesigning the overall loop – eliminating the need to rebalance the pipe network.

The result is a cooling circuit that remains short, controlled, and straightforward to operate – even as density increases.
