“Water is the source of life, without water, life itself cannot exist. Humans, plants and animals – entire ecosystems and food chains depend on clean water to survive. Although nearly 70% of the Earth’s surface is covered with water, only 2.5% of it is fresh water suitable for use or drinking. The rest is salt water or sea water. Not only that, but only 1% of the fresh water we have easy access to, the rest is hidden in glaciers and snow.

Water is the source of life, without water, life itself cannot exist. Humans, plants and animals – entire ecosystems and food chains depend on clean water to survive. Although nearly 70% of the Earth’s surface is covered with water, only 2.5% of it is fresh water suitable for use or drinking. The rest is salt water or sea water. Not only that, but only 1% of the fresh water we have easy access to, the rest is hidden in glaciers and snow. Moreover, the risk of freshwater scarcity is increasing. According to the United Nations report, due to water use, population growth, and climate change, by 2025, about 1.8 billion people will live in water-scarce regions, and about two-thirds of the world’s population will face water stress. situation.
As more and more countries are affected by uncontrollable factors, how should our planet of 6.8 billion people obtain drinking water?
The task seemed daunting, and Danfoss faced it head-on with its key desalination products. The company is working with ADI to leverage ADI’s breakthrough condition monitoring technology to deliver fresh water in an energy-efficient and efficient way to areas that need it.
Innovation changes the world
Danfoss is an innovative engineering technology company headquartered in Denmark, dedicated to enabling “the world of tomorrow to achieve more with less”. Its business scope covers infrastructure and food supply, as well as energy efficiency and environmental protection solutions. Danfoss products and services can be found in refrigerators, air conditioning, heating, motor control and mobile machinery.
Danfoss, a recognized leader in energy-efficient and high-performance products, is now working on desalination processes to extract fresh water from seawater through seawater reverse osmosis (SWRO) technology, hoping to make the world a better place.
Danfoss has decades of experience developing components for critical applications, including many cutting-edge innovations such as axial pump technology. The company has used this technology to become a leader in the advanced SWRO industry and has gradually expanded its global footprint to provide fresh water to areas that need it, especially in developing countries.

SWRO: Provide an adequate supply of fresh water
Seawater desalination (or seawater reverse osmosis, SWRO) technology is currently recognized as one of the excellent solutions to the shortage of fresh water. But there are some challenges in using the technology itself, not to mention the huge energy (and cost) required to extract fresh water from seawater. Because the salt in the water forms a stable chemical bond with the water, it is difficult to break it down and extract the water alone, so it takes a lot of energy.
Not only that, but the energy cost of operating a desalination plant is almost half the cost of obtaining fresh water from sea water.
Danfoss uses its four core technologies to provide energy-efficient desalination solutions to solve this energy consumption problem. The four core technologies include: high-pressure pumps, drives, energy recovery, and pressure and water flow control. These advanced technologies combine to provide cost-effective, long-lasting water purification solutions.
Danfoss high-pressure pumps are at the heart of more than 20,000 seawater reverse osmosis treatment systems worldwide. Typically used in island communities and large cruise ships, where a stable supply of fresh water is critical. The simple design of these pumps with only a few moving parts allows for easy maintenance, long service intervals and extremely high efficiency, up to 92% depending on the size of the pump.
Danfoss follows the philosophy of sustainable development, focusing on improving resource utilization, reducing risk, and honoring its reputation and commitment. ADI holds the same view in the development of breakthrough technologies.
OtoSense: Applying Sensory Interpretation to Quality Control
Analog Devices started with a workshop in partnership with Danfoss to discuss its vision, development plans and technology. We have therefore identified areas of potential collaboration, including a number of industrial technologies and systems that could help Danfoss accelerate smarter, more sustainable designs.
Among these technologies, ADI OtoSense™ is particularly noteworthy, especially its quality control capabilities. OtoSense is an AI-driven platform capable of sensing and interpreting sound, vibration, pressure, current, temperature and more in real-time for continuous condition monitoring and on-demand diagnostics. It detects anomalies on its own, learns continuously by interacting with domain experts, creates a digital fingerprint to help identify failures, and can predict failures early enough to avoid costly downtime, damage, or major failures.
OtoSense AI quality control on the production line
Danfoss decided to use ADI’s OtoSense quality control technology in a pump testing process pilot project to ensure its pump equipment was healthy and functioning properly. These tests are energy-intensive, and using ADI OtoSense in the tests, Danfoss was able to reduce energy output by 23 percent and potentially up to 50 percent in the future, is a demonstration step in helping Danfoss reduce carbon emissions.
By ensuring Danfoss’ pumping equipment is operating at peak levels and reducing maintenance time, ADI ultimately hopes that OtoSense can provide greater predictability, consistency, higher productivity and product quality, while reducing energy output and environmental impact.

ADI and Danfoss: Moving forward together for a better future
ADI and Danfoss have a long-standing partnership of over 20 years and share the same vision to further improve the world through technology. ADI has previously supplied components to Danfoss, but has not collaborated to create a complete system-level solution.
Today, Danfoss and ADI have a stronger partnership, innovating for a shared purpose and improving communities around the world by driving change, including implementing desalination for fresh water, while utilizing energy-efficient technologies to reduce environmental impact.
"Our collaboration[with ADI]revolves around artificial intelligence and CbM. When we realized that their technology could help detect and diagnose specific problems in our pump equipment, not just find out what might be a general problem We’re very happy when we’ve got the scope, and then we can diagnose the failure. This helps us learn quickly, and we can expect faster and more efficient post-testing as a result.”
