Our Approach
From initial assessment through design, build, and ongoing operations — a structured, low-risk pathway to deploying immersion cooling in Australian data centres and critical infrastructure.
Stage 1
We begin every engagement with an honest assessment of whether immersion cooling is the right fit for your facility, workload, and constraints.
On-site review of floor loading capacity, existing HVAC and electrical infrastructure, heat rejection options, and facility layout. We identify constraints early that influence deployment viability.
Analysis of current and projected heat densities (kW per rack), workload profiles, and growth trajectory. We model thermal requirements to size systems correctly.
Total cost of ownership comparison: immersion vs continued air cooling. Typical payback ranges: 2–5 years depending on scale, energy costs, and facility constraints.
Stage 2
Custom architecture tailored to your facility, workload density, and operational requirements.
Selection and sizing of immersion tanks — typically 4–20 nodes per tank. Rack layouts, cable management, and maintenance access designed for operational efficiency.
Vendor-neutral evaluation of dielectric fluids: mineral oil, synthetic esters, and engineered two-phase fluids. Consideration of thermal performance, longevity, and Australian supply chain.
Secondary cooling loop design: dry coolers, adiabatic systems, or chiller integration. Optimised for Australian climate zones. Typical approach temperatures: 3–8°C above ambient.
Stage 3
Procurement, fabrication, installation, and commissioning. Turnkey or assisted-build options.
Vendor-neutral sourcing of tanks, fluid, heat exchangers, pumps. Typical lead times: 4–12 weeks depending on equipment type and supply chain conditions.
Assembly and placement of tanks, plumbing, heat rejection, electrical tie-ins. Typical pilot deployment: 6–8 weeks from equipment arrival to first workload.
Fluid fill, leak testing, pump and control verification, thermal validation. Baseline PUE measurement, operational documentation, and staff training included.
Stage 4
Ongoing support for mission-critical immersion cooling systems.
Integration with DCIM and BMS. Fluid temperatures, flow rates, pump status. Optional 24/7 NOC support for critical deployments.
Periodic fluid quality testing, top-up procedures, replacement schedules. Typical single-phase fluid life: 5–10+ years with proper maintenance.
Scheduled inspections of pumps, seals, filters, heat exchangers. Quarterly for standard deployments; monthly for high-availability environments.
Use Cases
Representative deployment scenarios where immersion delivers clear advantages over traditional cooling.
GPU clusters (H100, B200, and beyond) generate 50–100+ kW per rack. Air cooling cannot support these densities; liquid cooling becomes mandatory. Immersion offers no per-node plumbing, simplified maintenance, and tolerance for dense GPU-to-GPU topologies. Typical deployments: 8–64 GPUs per tank.
Universities, CSIRO, and research institutions running simulation, weather modelling, genomics, or CFD at 20–40 kW per rack. Immersion reduces cooling energy by 40–50% and increases density for expansion within constrained space. Stable thermal environments support reproducible results.
Data sovereignty, secure supply chains, and deployability in austere environments. Self-contained tanks reduce reliance on facility HVAC; lower acoustic signatures benefit tactical deployments; Australian-owned consulting avoids foreign dependencies for sensitive infrastructure.
Reduce PUE, extend hardware life, and increase density without building new facilities. Immersion retrofits deploy in existing space — floor loading is the primary constraint. Target: 30–50% cooling energy reduction and 50+ kW per rack support.
Mining sites, offshore platforms, remote telecommunications, and regional facilities where traditional HVAC is impractical. Self-contained immersion units: no CRAC, reduced electrical load, operation in harsh environments. Container-based solutions available.
The Numbers
Typical ranges for comparison. Actual performance depends on facility design, climate, and workload.
| Metric | Immersion Cooling | Air Cooling |
|---|---|---|
| PUE (typical) | 1.02 – 1.10 | 1.3 – 1.6 |
| Rack density | 50 – 100+ kW per rack | 10 – 20 kW per rack |
| Cooling noise | ~60 – 65 dB (pumps only) | ~75 – 85 dB (fans, CRAC/CRAH) |
| Floor footprint | Higher density = less m² per kW | Larger footprint for same compute |
| Maintenance | Fluid testing, pump/filter service | Filter changes, CRAC service, ductwork |
| Facility requirements | Floor loading, fluid plumbing, heat rejection | Raised floor, HVAC, ductwork |
| Hardware compatibility | Immersion-ready servers (OEM or retrofit) | Standard servers |
Values are indicative. Site-specific assessment recommended.
