Our Technology | Field Record
Proven, not promised.
A machine that meets the climate test on paper but cannot run continuously in the field is a supplement, not a supply. WaHa publishes its climate prediction, then publishes the field record measured against it. This page is that record.
The WaHa Vaporator® is the first atmospheric water generation architecture with a published field record measured against its climate prediction: 17 months of continuous operation at Khalifa University in the UAE, 10,143 hours logged, 95 percent of nameplate production delivered, and over 96 percent of climate-predicted output achieved, with 99.999 percent measured uptime across monitored machines in the UAE and Sweden.
The principle
Prediction first. Then proof.
Every vendor claims its machines work; the industry has never defined working. WaHa applies a utility standard: a location counts as viable only when a machine delivers at least 90 percent of its rated daily production on at least 90 percent of days, computed from four years of public climate data. That prediction is published openly on the Where It Works page, where anyone can run any location, and the architectures are compared on the AWG Technology Platforms Comparison page.
A prediction is only half the test. The other half is whether the machine shows up: uptime, production against prediction, and degradation, measured in the field over time. This page holds that half.
We publish where the WaHa Vaporator® meets a utility-grade standard, and where it does not, using four years of global climate data.

Seventeen months. One machine. No breaks.
A WaHa Vaporator® ran continuously for 17 months at Khalifa University in the UAE, through two full desert summers. It logged 10,143 hours of operation, delivered 95 percent of nameplate production, and achieved over 96 percent of the water output the climate model predicted for that site. Prediction, then proof, on the same machine.
Reliability
Fifteen minutes of downtime in 1.2 million.
Three monitored machines, in the UAE and in Sweden, accumulated more than 1.2 million combined operating minutes with a total of 15 minutes of unplanned downtime: 99.999 percent measured uptime, in conditions ranging from desert heat to Nordic cold. Production held above 96 percent of target across seasons for more than a year in the UAE.
The engine behind the record
The record belongs to the engine.
The thermodynamic engine at the center of every WaHa Vaporator® is a sealed, closed-loop heat pump architecture, protected by WaHa’s foundational patents, that recovers the latent heat of condensation and uses it to do the work again. That recovery is why the machine runs continuously where other architectures derate or stop. Read how it works on The WaHa Vaporator® Engine page, and explore the WaHa patent portfolio.
The record
Measured, not modeled.
An open standard
We published our record first. We invite every vendor to do the same.
WaHa has proposed an industry-wide performance standard for atmospheric water harvesting: where machines work, what they truly cost to run, what comes out of the tap, and whether they show up in the field. WaHa published its own declaration and field record first, and submits to the same test as everyone else. The methodology and the interactive tool are public on the Where It Works page.
Questions people ask
Field record FAQ
How long has the WaHa Vaporator® run in the field?
One machine ran continuously for 17 months at Khalifa University in the UAE, logging 10,143 hours and delivering 95 percent of nameplate production. Pilot systems have operated across the UAE, Saudi Arabia, Sweden, and the United States.
What does 99.999 percent uptime mean in practice?
Three monitored machines in the UAE and Sweden accumulated more than 1.2 million combined operating minutes with 15 minutes of unplanned downtime. That is the measured record, not a target.
How does the field record compare to the climate prediction?
The 17-month UAE run delivered over 96 percent of the water output the public climate model predicted for that site, closing the loop between prediction and proof.
