Next-Generation Industrial Desiccant Materials
The new technology we have developed is a new class of next generation industrial desiccant materials called Regeneration Optimized Sorbents (ROS). Our first commercially available material is ROS-037, it has the world’s best kinetics of operation. ROS-037’s practical application is to replace the silica material used in commercial desiccant dehumidifiers, to reduce the amount of power used and lower their exhaust temperatures. The technology emerged from decades of research, is compatible with desiccant dehumidifier rotor manufacturing techniques and processes, and has the power to disrupt the global air and humidity management industry worldwide.
The key feature is that the new material acts just like traditional desiccants, but regenerates (dries out) at a much lower temperature (49°C instead of up to 200°C). The result is dramatically improved energy-efficiency and lower temperature exhaust from buildings HVAC systems, a functional way to stop carbon emissions before they start.
The lower temperature is achievable due to ROS-037’s superior kinetics. It solves the number one limiting factor of the dehumidifier market, power consumption, by simply lowering the temperature required to expel unwanted humidity in the outside environment, making it an obvious choice replacement material for energy-inefficient silica based materials used today in the multi-billion dollar per year market.
An important second benefit of the lower temperature operation, is that the humid exhaust from the dehumidifier can now be used to provide a decentralized potable water supply on demand. This is made possible by simply feeding the humid dehumidifier exhaust stream into an inexpensive, simple refrigeration unit to condense the water vapour into liquid, potable water, thus enabling you to offset your building’s water use and help conserve both energy, and water.
The result is better energy efficiency, lower operating costs, better environmental emissions and a new source of potable water from air. This technology has the potential for massive, positive global impacts when fully adopted by the market.
“We have discovered a sorbent that has improved the kinetics and energetics of water adsorption/desorption by far over conventional desiccants.”

“HOW IT WORKS” IN HUMIDITY MANAGEMENT
Our new designer desiccant is revolutionary for the humidity management market, because its superior kinetics lowers the operating exhaust temperature dramatically, reducing operating expenses and emissions from many industries where dehumidification is important, including pharmaceutical, food packaging, dairy production, chemical processing, cosmetics manufacturing, petroleum refining office building HVAC management systems and many others.
“HOW IT WORKS” for ATMOSPHERIC WATER GENERATION
Water from air takes its origins in the development of commercial refrigeration equipment. It has seen recent increasing popularity as water scarcity becomes an ever increasing problem, but has historically been held back from widespread adoption due to its limited operating environment limitations and high energy per liter needs.
We wanted to develop a method where a desiccant dehumidifier could feed a traditional atmospheric water generator (AWG), to gain the advantages of operating in cold and dry environments where traditional AWG systems fail.
To do this we developed a new low temperature regeneration desiccant, so that the humid exhaust of the desiccant dehumidifier would be cool enough for the refrigerant dehumidifier to operate. This would allow a desiccant dehumidifier to feed warm humid air to the intake of a traditional AWG system, allowing it to work in any environment, thus removing the barriers to adoption.
The low temperature desiccant we developed is called ROS-037 (“Regeneration Optimized Sorbent Formula 37”), which allows the desiccant dehumidifier to operate at 122°F instead of 400°F, and work successfully in environments down to 12% relative humidity. We built a prototype (pictured at right) to demonstrate the technology operation as a proof-of-concept to show that dehumidifiers can now be more efficient, and used to provide a new water source using normal dehumidifier equipment, functionalized by the new material.
PROTOTYPE ATMOSPHERIC WATER GENERATOR FROM OFF-THE-SHELF DEHUMIDIFIERS
We partnered with Design 1st of Ottawa, Canada to design a working prototype of our Atmospheric Water Vapor Generator Supercharger. The prototype was designed and built to demonstrate that the new ROS-037 material can transform off-the-shelf dehumidifiers to become atmospheric water generators (AWG) with light modifications. The unit can even operate in environments that are too cold and/or dry where traditional AWG systems fail to work.
