AIR IN.
WATER OUT.
AirJoule® is a transformational climate technology that enables the atmosphere to become an around-the-clock energy and water resource.
The Technology Advantage
Conventional dehumidification systems are reliant on a vapor compression and refrigerant system from the early 1900s. In over a century, there have been few technological breakthroughs to disrupt this sector…until now.
Our technology solved thermal constraints related to metal organic frameworks (MOF)s, which have previously prevented commercialization of MOFs.
Using our proprietary MOF technology and coating system, we solved the need for external heat to release water vapor during the desorption process. This means that instead of using excess external heat – we’re able to harness heat from the absorption process, reducing the need for energy and allowing the chambers to release the water vapor.
Unlike conventional systems, AirJoule eliminates the need for harmful refrigerants and works in both humid and arid environments.
AirJoule®’s proprietary technology efficiently dehumidifies air and produces pure, PFAS-free, distilled water.
How AirJoule® works
- Air is drawn through MOF-coated contactors and water vapor is captured.
- Once MOF is full of water vapor, chamber doors close and vacuum is applied.
- Under vacuum, water vapor is released to the vacuum swing compressor (VSC).
- VSC slightly compresses water vapor so that it condenses to liquid water inside the vacuum condenser.
- Water vapor capture and release cycles occur simultaneously in separate chambers; internal heat is recovered which enables superior energetics.
AirJoule® enables commercialization of MOFs
MOFs are highly adsorbent coatings, engineered to capture specific molecules (in this case, water vapor).
AirJoule Technologies has engineered a proprietary MOF coating (MTMOF1) that can hold more than half its weight in water vapor.
Thermal constraints have limited the potential of MOFs in historical dehumidification efforts.
Heat generated by adsorption cycle and additional heat required to desorb the MOF are problematic for cooling applications.
AirJoule® solves the energetics issue, resulting in an unprecedented reduction in energy consumption for dehumidification.
Proprietary pressure swing system integrates adsorption and desorption functions, so the heat of adsorption can be used to assist desorption under vacuum, eliminating the need for additional energy.
