Turn the Hall You Already Have into a 140 kW-per-rack Liquid-Cooled AI Floor.
Direct-to-chip and rear-door heat-exchange deployments engineered into facilities you already control — slab, electrical and thermal assessment, CDU and manifold design, installation and commissioning, without a greenfield build.
Who This Is For
- Enterprises with an air-cooled hall at 8–15 kW per rack that now needs GPU rows
- Colocation tenants who want NVL72-class racks in their existing cage
- Operators of older facilities who need to extend asset life into the liquid-cooled era
- Teams that have been told their building cannot host GPUs and want a second opinion
What's Included
Retrofit Assessment
Structural review of slab and raised floor for 1,600 kg racks, electrical capacity to the row, chilled-water or condenser-water availability, pathway and containment.
Cooling Architecture
Direct-to-chip with row or in-rack CDUs where density demands it; rear-door heat exchangers where 40–60 kW per rack is the target; hybrid designs for mixed rows.
Hydraulic Design
Secondary loop sizing, manifold and quick-disconnect layout, coolant chemistry, filtration, leak detection and isolation strategy.
Electrical Upgrade
New or upgraded busway and PDUs to 415 V, breaker coordination, UPS review and generator load check.
Installation
Pipework, CDU placement, manifolds, rack integration, pressure and leak testing, flushing and fill.
Commissioning
Thermal mapping under load, flow balancing, alarm integration into BMS/DCIM, and operator training on loop maintenance.
Reference Specifications
Starting points. Every engagement is engineered to the workload, site and budget in front of us.
| Density range | 40–60 kW per rack with rear-door HX; 100–140 kW per rack with direct-to-chip liquid |
|---|---|
| CDU options | In-rack (to ~100 kW), row-level (to ~1.5 MW), facility-level skids; CoolIT, Motivair, Vertiv, Boyd |
| Loop temperatures | Facility water W32 or W45 supply; secondary loop 25 °C supply / 45 °C return typical |
| Heat rejection | Existing chillers, dry coolers for free cooling, or heat reuse to building hot-water systems |
| Structural | Point-load and distributed-load checks for 1,600 kg loaded racks on slab or raised floor |
| Monitoring | Flow, pressure, temperature and leak sensing integrated to BMS, DCIM and the cluster's observability stack |
How We Deliver
- 1
Assessment
Weeks 1–2Site survey, drawings review, structural and electrical capacity confirmation. Output: feasibility report with options and budget.
- 2
Design
Weeks 2–4Hydraulic, electrical and mechanical packages, landlord or AHJ submissions, equipment selection and ordering.
- 3
Install
Weeks 4–8Pipework, CDUs, manifolds, busway and PDUs installed with the hall live where required.
- 4
Commission
Weeks 8–10Pressure test, flush and fill, thermal mapping under synthetic load, alarm and runbook handover.
Questions We Get Asked
Can the retrofit happen while the hall stays in production?
Usually yes. We phase work by row, isolate new pipework from live equipment, and schedule tie-ins to existing plant during agreed maintenance windows.
Our facility has no chilled water. Can we still go liquid?
Yes. Dry coolers or packaged chillers on the roof or pad feed a facility loop; with warm-water design temperatures most Texas sites free-cool for the majority of the year.
What about leaks?
Modern cold-plate systems run at low pressure with dripless quick-disconnects, and we install leak detection at every manifold and CDU with automatic isolation. The loop is pressure-tested before any rack is energised.
