The brief
Air is the only building service that cannot be inspected by eye. Dead zones, recirculation and bypass airflow are invisible until the hardware throttles or the occupants complain — by which point the ductwork is in the ceiling and the containment is built.
We model the space before it is built. Navier-Stokes simulation predicts thermal stratification with high accuracy, so containment strategy, set points and fan curves are decided against data rather than rule of thumb.
Core competencies
Three analysis disciplines, applied individually or as one thermal strategy.
CFD mapping
High-fidelity visualisation of air patterns using Navier-Stokes modelling to eliminate dead zones and optimise laminar flow. Steady-state analysis, transient thermal modelling and turbulence intensity maps.
Submerged cooling
Dielectric liquid immersion for ultra-high-density compute, pushing PUE towards 1.0. Single-phase immersion, heat rejection networks and dielectric fluid dynamics.
Wind pressure
High-rise structural wind analysis to protect façade integrity and unlock natural ventilation. Pedestrian comfort studies, vortex shedding mitigation and cladding load analysis.
Data centre thermal optimisation
Aeropack Infra specialises in radical hot/cold aisle containment. By physically decoupling supply and exhaust air we eliminate recirculation and bypass, which allows a meaningful increase in supply set-point temperature — the single largest lever on data-centre energy cost.
- Precision humidity control — moisture management to prevent ESD and corrosion in sensitive hardware
- AI-driven fan curving — dynamic CRAC adjustment against real-time server load heat maps
- Containment integrity testing — leakage measured, not assumed
Technical telemetry
Real-time benchmarks from active deployments.
Industry leader tier for the deployed cooling topology.
Rejected heat exported to district heating rather than atmosphere.
Average across the containment envelope.
Critical redundancy maintained through the cooling chain.
Submerged liquid cooling
Total thermal immersion. Submerging hardware in non-conductive fluid achieves orders of magnitude more heat transfer capacity than air cooling — the practical route for AI training clusters and other high-density racks.
Modular scalability. Liquid tanks are designed around standard server rack footprints, allowing hybrid air/liquid transitions inside existing white space rather than a full hall rebuild.
You cannot commission what you cannot see. Modelling the air first is the cheapest engineering hour on the project.
