TRADITIONAL COOLING

Precision Thermal Management

High-density AI workloads generate heat loads that conventional air cooling cannot address. DARKNX designs and deploys liquid, immersion, and hybrid cooling systems engineered specifically for the thermal demands of GPU and HPC infrastructure.

DENSITY-FIRST DESIGN

DARKNX cooling systems are specified around the actual thermal outputs of the compute hardware being deployed, not around a generalised standard. Every rack density target is designed to, not designed around.

IN-HOUSE CHILLERS

DARKNX manufactures its own chiller units, enabling tighter integration with the broader thermal and power architecture and eliminating lead time dependencies on external cooling vendors.

REDUNDANCY BY DEFAULT

All DARKNX cooling designs include N+1 minimum redundancy at the cooling plant level, with topology options up to 2N for mission-critical deployments where no single failure can impact availability.

DEPLOYMENT CAPABILITIES

Single-Phase Liquid & Air-Cooled Environments.

Not every deployment demands two-phase cooling. DARKNX designs, specifies, and delivers single-phase liquid cooling and precision air-cooled environments for projects where density targets, site conditions, or operational requirements call for proven, cost-effective thermal infrastructure.

SINGLE-PHASE LIQUID COOLING

Precision Liquid, Purpose-Built

Single-phase liquid cooling uses chilled or ambient-temperature water flowing through cold plates and rear-door heat exchangers to remove heat from compute hardware. DARKNX integrates single-phase systems across greenfield, brownfield, and modular deployments, including facilities that require a phased migration path from air to full liquid cooling.

TECHNOLOGY Cold plate, rear-door HEX
RACK DENSITY RANGE Up to 120kW per rack
FLUID Water / glycol solution
INTEGRATION Chilled water or direct expansion
BEST FOR AI inference, mixed workloads
  • ,Compatible with existing chilled water plant infrastructure
  • ,DARKNX in-house CDU manufacturing eliminates vendor lead times
  • ,Phased upgrade path to two-phase DTC as workloads scale
  • ,N+1 redundancy at the cooling plant level, standard
AIR-COOLED ENVIRONMENTS

Precision Air, Where It Fits

Air cooling remains the right solution for many deployments, particularly enterprise colocation, edge computing, and lower-density compute environments. DARKNX designs precision air-cooled data halls with hot/cold aisle containment, CRAC/CRAH units, and computational fluid dynamics (CFD) modelling to maximize efficiency before liquid cooling is required.

TECHNOLOGY CRAC / CRAH, in-row cooling
RACK DENSITY RANGE Up to 80kW per rack
CONTAINMENT Hot / cold aisle, chimney
FREE COOLING Economiser & adiabatic options
BEST FOR Colocation, networking, storage
  • ,CFD airflow modelling to eliminate hot spots before construction
  • ,Hot/cold aisle containment as a baseline design requirement
  • ,Economiser and free cooling integration to reduce mechanical plant load
  • ,Designed with a clear upgrade path as compute densities increase
