    Air-to-water technology

    Solaq develops atmospheric water generation technology that provides an alternative water source, independent of traditional infrastructure, adaptable to local conditions, and designed for continuous, reliable operation.

    Fixed production

    Each unit is designed for a fixed daily output across climates: 500 or 2,500 litres per day, scalable up to 25,000 by deploying units in parallel.

    Any climate

    Cooling-based AWG uses electricity to chill air below its dew point, with output diminishing as air gets drier. Our liquid desiccant process works at lower humidity and runs on heat instead.

    Runs on heat

    Low-grade heat drives production, from electricity or from stranded waste heat. Remote industrial sites turn heat they can't use into water for their operations.

    Frequently asked questions

    Common questions about our technology and approach.

    In short: Solaq uses liquid desiccant technology to extract water from ambient air. Unlike conventional cooling-based AWG systems, our decoupled absorption-regeneration process is designed for a fixed daily output across climates: 500 litres per day for Pura Deploy and 2,500 for Pura Community. Multiple units can be deployed in parallel up to 25,000 litres per day. The system runs on low-grade heat from industrial waste heat, solar thermal or grid electricity, requires minimal maintenance, and produces safe drinking water.

    Water scarcity is no longer a distant problem. Climate variability, aging infrastructure, and growing demand are putting water security at risk across regions and industries. For many places, the only solution that people and businesses have is to transport water over large distances. At Solaq, we develop Atmospheric Water Generation (AWG) technology as a reliable alternative water source. Our systems are designed to operate independently of traditional infrastructure, adapt to local conditions, and deliver continuous, dependable output.

    Liquid desiccant air-to-water generation uses hygroscopic (water-attracting) liquid solutions to absorb moisture from ambient air. The absorbed water is then released through a heat-driven regeneration process, condensed, and treated to produce clean water. This approach can operate effectively across a wider range of humidity conditions compared to conventional cooling-based systems.

    Most Air-to-Water or Atmospheric Water Generation technologies rely on cooling condensation, which limits their output based on system size and local climate conditions. Compared to other liquid desiccant systems, Solaq's unique configuration decouples the absorption and regeneration steps, enabling controlled and stable water production with reduced sensitivity to seasonal and climate variability, delivering more predictable output year-round.

    By decoupling the absorption and regeneration steps, we can scale the number of absorbers to match local climate conditions, drier climates simply require more absorbers. The regeneration process stays the same from site to site, which keeps its efficiency consistent. This modular approach is what lets us design each unit for a fixed daily output across climates.

    Pura Deploy is designed for 500 litres per day and Pura Community for 2,500 litres per day. Both are building blocks of an integrated modular platform: multiple units can be deployed at a single site, sharing infrastructure and operating as one coordinated system, up to 25,000 litres per day. Above that, we design custom plants around the waste heat of industrial processes.

    The regeneration process requires low-grade heat. This can be industrial waste heat at 55 to 75°C, or heat from a grid connection, solar-PV, solar thermal collectors or a (diesel) generator. This flexibility enables deployment in off-grid or energy-constrained environments while maintaining sustainable operation.

    Yes. Regeneration needs low-grade heat at 55 to 75°C, the range many industrial sites release unused. Typical sources are diesel genset jacket water, gas turbine and microturbine exhaust, electrolysers, refineries and process cooling loops.

    Heat that was lost becomes water. The site makes its own water without burning extra fuel for heat, and relies less on trucked or bottled supply.

    Absorption and regeneration are decoupled. The absorbers keep taking up moisture while regeneration follows the heat that is available.

    Energy consumption is dependent on system size, the type of available energy source, and the local climate and seasonal variations. We're happy to work through this with you and assess whether our system is the right fit for your challenge. Let's work through the numbers together.

    Our system is designed for easy, minimal maintenance, built with durable components and a closed-loop desiccant cycle that reduces wear and complexity. Recurring maintenance can be performed by local partners with components available around the world. Maintenance includes periodic inspections, filter replacements, and routine system checks. Remote monitoring capabilities enable predictive maintenance, helping to identify potential issues early and reduce the need for on-site intervention.

    Typical requirements include adequate space for the system units, access to a low-grade heat source or electricity source (or installation of solar collectors), and basic infrastructure for water storage and distribution. Our team provides site assessment and planning support to ensure successful deployment.

    Water undergoes polishing and treatment as part of the production process. Monitoring systems track quality parameters in real-time. Specific treatment steps are configured based on intended use and local requirements. Our team can discuss details during the consultation process.

    Yes. Drinkable water output is a standard feature of our systems, achieved through post-processing steps that meet industry standards for potable water quality.

    Beyond (remineralised) drinking water, the pure water produced by our systems can be used as process water in industrial applications, datacenters, or even for green hydrogen electrolysis. This versatility allows us to serve a wide range of customers facing different water challenges.
