Rack Immersion Cooling
Next-generation thermal management for high-density data centres — engineered to meet the demands of modern AI, HPC, and enterprise infrastructure. As rack densities increase and GPU and CPU thermal loads push beyond what air cooling can reliably handle, immersion cooling delivers a fundamentally more efficient and scalable solution.
What is Rack Immersion Cooling?
Rack immersion cooling is a method of thermal management in which server components — including GPUs, CPUs, storage drives, memory modules, power supply units, and networking hardware — are submerged directly in a non-conductive dielectric fluid. Unlike traditional air-cooling systems, the fluid makes direct contact with heat-generating components, absorbing and dissipating thermal energy with dramatically greater efficiency.
As data centres scale to accommodate increasingly power-dense workloads — particularly AI and machine learning infrastructure driven by high-performance GPUs — conventional air-based cooling reaches its physical and economic limits. Rack immersion cooling removes that ceiling entirely. It enables stable, sustained operation of ultra-dense compute clusters while significantly reducing energy consumption, infrastructure footprint, and operational noise.
There are two primary approaches: single-phase immersion, where the fluid remains in a liquid state throughout the cooling cycle, and two-phase immersion, where the fluid boils at low temperatures and is recovered as vapour before returning to the tank. Both methods deliver cooling performance that far exceeds what air or even liquid-to-chip solutions can achieve.
Why rack immersion cooling methods Fail
01
Fluid Contamination
Introducing incompatible materials, incorrect hardware, or poorly maintained components into the dielectric fluid contaminates the entire tank — degrading cooling performance and damaging every submerged component simultaneously.
02
Poor Facility Preparation
Immersion cooling requires structural reinforcement, drainage planning, and power upgrades that many facilities are not designed for. Deploying without proper site preparation leads to leaks, overloading, and premature system failure
03
Inadequate Maintenance
Dielectric fluid degrades over time and requires regular testing and replacement. Facilities that treat immersion cooling as a fit-and-forget system eventually face thermal inefficiency and hardware damage from fluid that no longer performs to specification.

Key Features
GPUs & CPUs
Dielectric fluid prevents thermal throttling, sustaining peak clock speeds across AI, rendering, and HPC workloads.
Storage
Hard drives and NVMe SSDs operate in a sealed, contaminant-free environment, improving consistency and eliminating fan-related failures.
Memory
A stable thermal envelope reduces cycle stress on DRAM and HBM modules, improving reliability and long-term data integrity.
Power Supply Units
PSUs run within rated thermal margins with no internal fans, eliminating a primary source of mechanical failure and noise.
Networking
Switches and adapters maintain stable thermal conditions at line rate, preventing packet loss and latency spikes from heat buildup.
Full System Efficiency
A single fluid bath cools all components simultaneously, delivering a PUE approaching 1.03 and reducing operational costs at scale.
