How we operate

A performance-assurance model, not an MEP shop

We don't deliver blueprints and walk away. We deliver a guaranteed thermal and power environment — front-loaded to eliminate risk before a single pipe is cut.

The model

Surgical, front-loaded, and built off-site

01

CFD & digital twin first

We build a complete digital replica of your room and prove how liquid loops interact with your existing air cooling — showing the exact thermal displacement before you commit capital.

02

Modular prefabrication

CDUs, manifolds, and pump systems are built and tested in a controlled environment, then delivered ready for drop-in connection — cutting deployment from months to weeks and slashing on-site risk.

03

Closed-loop lifecycle

The engagement doesn't end at handover. Ongoing thermal tuning, fluid-quality management, and predictive maintenance keep the envelope inside spec for the life of the deployment.

Honest metrics

We measure what actually matters

PUE is a blunt instrument that breaks the moment liquid cooling enters the room — it changes both the numerator and the denominator, so it can't honestly compare air and liquid. We baseline, report, and engineer against the metrics that actually hold up.

TUE
Total Usage Effectiveness

The true measure of liquid-cooling efficiency — total facility energy against the power that directly drives compute.

WUE
Water Usage Effectiveness

Water consumed per unit of IT energy — increasingly the metric that determines whether a site can even be permitted.

Headroom
Power & thermal headroom

Across today's power-constrained grid, your binding constraint is a fixed MW envelope. We track and unlock the compute you can actually land inside it.

Engagement

Three phases, aligned to your risk

Each phase stands alone and de-risks the next. You can stop after the audit — most clients don't.

01

Thermal Audit

Identify the catastrophic risks in your existing infrastructure before any AI pods are installed.

Deliverable

3D thermal map, CFD density ceiling & TUE baseline.

02

Surgical Design-Build

Turnkey installation of specialised CDUs, manifolds, cold plates, and power routing.

Deliverable

A fully commissioned, validated hybrid-cooling pod.

03

Performance SLA

A bounded guarantee that the thermal and power environment holds for your stated workload.

Deliverable

Continuous monitoring and shared-risk KPIs.

The guarantee

How the SLA is actually structured

Vague uptime promises don't survive contact with a hedge fund's legal team. Ours are precise, measurable, and bounded — we guarantee the environment, defined exactly, and back it with live telemetry.

Tier 1

Design Assurance

Guarantee — The as-built environment meets the CFD-validated spec at commissioning — inlet temperature, ΔT, flow rate, and power headroom — for your stated IT load.

Remedy — Any shortfall is corrected at our cost. No ambiguity, no allowances.

Tier 2

Monitored Envelope

Guarantee — Continuous telemetry on every loop, with a guaranteed response time to any anomaly and monthly TUE, headroom, and fluid-quality reporting.

Remedy — Defined service credits if response-time commitments are missed.

Tier 3

Shared-Risk Performance

Guarantee — A contractual ceiling on thermal-throttling events for your defined load profile — measured against clear, instrumented KPIs, not your software.

Remedy — Shared-risk credits tied to those KPIs, with bounded, insured liability.

What we never do: guarantee your software, or pretend a mechanical SLA replaces redundancy and insurance. We assure the physical envelope — the part we control, instrument, and can prove.
