Water from air, made where it is needed
The AirJoule technology captures water vapor from ambient air and uses low-grade waste heat to release it as pure distilled water. Anywhere there is air and heat, there is a supply of water that does not depend on a pipeline, a well or a truck.
Built for facilities that have heat and need water
Most facilities throw away low-grade heat: server racks, process cooling, refrigeration, generators, boilers. The AirJoule technology turns that heat into the energy input for water generation. It fits wherever water is scarce, expensive, permitted or trucked in, and wherever a facility wants to reduce its draw on the local supply.
Data centers.
Liquid cooling rejects heat without water; the AirJoule technology turns that heat into water for data center facility use.
Industrial facilities.
Food and beverage, semiconductors and chemicals, and other process industries with waste heat and high water demand. Water for process use, boiler feed or humidification.
Cool without consuming water. Then make some.
AI racks draw 40 to 150 kilowatts, and the heat has to go somewhere. Water has also become a permitting condition: New York’s July 2026 moratorium on data centers of 50 MW and above and Texas’s August 2026 pause on grid interconnections are signs that communities are asking how much power and water a data center will take before it is allowed to be built. Operators that can show a low-water or water-positive design have an easier path to approval.
Data center cooling systems, regardless of system architecture, all work by removing heat from the chips and dissipating it into the atmosphere. The AirJoule technology uses part of that rejected heat to generate pure distilled water on site. Leading data center operators have publicly committed to replenish more water than they consume by 2030, and on-site generation using AirJoule is one solution.
A 100 MW data center is a $3 billion to $5 billion build. On-site water generation is a small fraction of that, and the time it can save in permitting can be worth more than the equipment.
Pure distilled water, at industrial scale
AirJoule Prime is designed to produce up to 2,000 liters per day at under 200 watt-hours per liter when paired with low-grade waste heat, in a containerized unit with a standard hot-water connection and electrical supply. AirJoule Core serves smaller sites at up to 250 liters per day and can run on a heat pump where waste heat is not available. The water meets FDA bottled water standards and California drinking water standards, and can be delivered as distilled, potable or remineralized water for purpose.
Buy it, lease it, or pay per gallon
Systems can be purchased outright, leased, or delivered under a Water Purchase Agreement in which AirJoule Technologies owns, operates and maintains the equipment and the customer pays only for the water delivered, with no upfront capital and no rate escalation. Some engagements combine models depending on the customer’s capital strategy.
From Newark to Europe
The first full-scale AirJoule Prime was commissioned at our Newark, Delaware facility in May 2026 and has shipped to Europe for a deployment at a European data center in the fourth quarter of 2026, through our partnership with the Net Zero Innovation Hub for Data Centers, a consortium whose members include Google, Microsoft, Data4, Vertiv, Schneider Electric and Danfoss. AirJoule Core systems are deployed for customer demonstrations at GE Vernova’s Advanced Research Center in Niskayuna, New York and at Expo City Dubai.
