Above 100 kW a rack, liquid cooling isn't an upgrade — it's the design. Lose flow and the silicon throttles before a human reads the alarm.
Mission-critical HVAC · data centre cooling · critical environments
The AI operating layer for mission-critical cooling.
Your chillers, CDUs and air handlers are already watched — by a BMS, a DCIM, a controls network. None of them talk to each other. None of them own the work. We unify them into one operating layer.
Reads the systems you already run. Takes no control authority over any equipment.

01Mission-critical HVAC
One operating layer over every system that already watches your cooling.
It reads what your building systems see, works out what is actually wrong, and runs the repair through to proof.
01
It unifies what you already run.
BMS, BAS, DCIM, controls and sensors read into one place. Read-only — it takes no control authority and cannot change a setpoint.
02
It works out what is actually wrong.
Fifty alarms from one failing pump collapse into one incident, with one root cause, one owner and one clock.
03
It runs the work, and proves it.
The certified and cleared technician, the approved procedure, and telemetry confirming the condition genuinely cleared before anything closes.
02Why not the software you have
Cooling stopped being comfort. The software didn't notice.
Building HVAC software was designed for comfort — schedules, setpoints, tenant complaints. A data centre, a hospital, a fab runs cooling as infrastructure. Same equipment, entirely different job.
The systems stop at 03:17. The incident doesn't.
Most software tells you a number moved.
We tell you what sits downstream of it, and how many minutes of margin are left before it matters.

We close when the telemetry says the condition cleared — and reopen it when the telemetry disagrees.
03The operating layer
Devices below. Work above. One layer in between.
Your devices already produce the signal. Your teams already do the work. Nothing has ever owned the layer between them — so it happens on a phone call at 03:14.
The middle plane is the product. Everything else on this page hangs off it.
WorkRuns it
Dispatch, approved procedure, multi-party coordination and verified closure — across in-house engineers, OEM service and outside mechanical contractors. This layer is the product, not an integration.

04Critical environments
Seven places where an excursion is a loss, not a complaint.
The equipment is ordinary. The tolerance, the redundancy and the paperwork around it are not.
ASHRAE 170 · Pressure cascade
Hospitals & healthcare
Operating rooms and isolation rooms run on pressure cascades and humidity bands written into standards. An MRI magnet needs its chilled water first.

Pharmaceutical & life sciences
A validated cleanroom leaving its band doesn't fail quietly. It produces a deviation, an investigation, and sometimes a destroyed lot.
ISO 14644 · ±0.1 °C
Semiconductor & advanced manufacturing
Lithography bays hold temperature to a tenth of a degree because the process physics demands it. An excursion scraps wafers, not comfort.

Research laboratories
Vivariums carry regulated temperature ranges. Freezer farms hold sample libraries that took twenty years to build and cannot be collected again.

Refrigerated warehousing and pharmaceutical storage, where the temperature excursion log is part of the product's release documentation.

Telecom & network edge
Switch rooms and battery plants, where sustained heat quietly shortens the life of the batteries meant to carry the site through the next outage.
Different standards, different consequences, one identical gap between the alarm and the qualified hand.

Mission-critical HVAC, answered.
The questions that come up in every first conversation, including the ones that are really objections.
What is mission-critical HVAC?
Mission-critical HVAC is cooling for facilities where a temperature excursion causes loss rather than discomfort — data centres, hospitals, laboratories, cleanrooms and process manufacturing. The equipment resembles commercial HVAC. The tolerance, the redundancy and the governance around it do not.
How is data centre HVAC different from commercial HVAC?
Data centre HVAC is designed with redundancy, so a single failure rarely reads as an outage until the margin is already gone. Rack densities above 100 kW require liquid cooling loops, CDUs and rear-door heat exchangers rather than air alone. Access is governed by procedures and clearances that decide who may touch the equipment at all.
Doesn't the BMS already do this?
A BMS controls and observes equipment, but it does not run the response. It does not know which technician holds the OEM authorisation for that CDU, whether the required MOP was approved, or whether the repair actually cleared the condition. That work happens outside it, on a phone.
How is this different from a CMMS like Maximo?
A horizontal CMMS receives every alarm as its own event, so one failing pump can open fifty work orders for fifty downstream sensors. This layer holds the cooling chain, so it correlates those fifty signals into one root cause and gates dispatch on live certification and clearance rather than attaching a PDF checklist.
Couldn't we build this on Dynamics 365 or Salesforce Field Service?
You could, and integrators charge accordingly. Both ship the generic IoT-alert-to-work-order pattern as building blocks, both are designed to manage internal teams inside one tenant, and neither understands cooling topology out of the box. The hard parts are correlation across a thermal chain and orchestration between a facility owner and an outside contractor on separate systems.
Is this field service software, or something else?
It is field service software — a field operating system for mission-critical cooling. It runs the dispatch, the procedure, the technician and the closure, which means it replaces the platform doing that work today rather than syncing with it. What it does not replace is the observation layer: your BMS, BAS, DCIM and controls stay where they are, and we only read them.
06Design partners
Four weeks. Nothing connected until you say so.
We are looking for a small number of design partners running critical cooling at real scale. This is the whole commitment.
Mission-critical service contractors
Mechanical and precision-cooling divisions carrying uptime SLAs across other people's sites.
Colocation & enterprise operators
Mixed-vendor plant across several halls, without a hyperscaler-sized engineering team behind it.
Critical facilities management
In-house technicians, OEMs and subcontractors under a single availability commitment.
Week 1
We map one cooling system with your team — assets, dependencies, alarm sources. Nothing connected. A whiteboard exercise that produces a model.
Week 2
A read-only connection to one alarm feed, in a DMZ or against a historian. It writes nothing, anywhere.
Week 3
We replay your last 90 days of alarms and show what correlation would have caught, missed, and got wrong.
Week 4
Shadow mode on live alarms. Your team compares its call to ours on every incident, then decides whether this was worth the time.
01Which system raises your cooling alarms today?
02What happens between that alarm and someone qualified arriving on site?
03Where in that path do you lose the most time?
