Dais Analytic Completes Testing of Nanostructured Aqualyte-Based Cooling Tower Technology

Dais Analytic Corporation, a commercial nanotechnology materials business selling its industry-changing nanomaterial technology and designs into the worldwide air, energy and water markets, today announced it has successfully completed the testing of a new generation of safer, more efficient cooling tower technology it calls "PolyCool™" using the features of the Company's Aqualyte™ nanomaterial.

PolyCool™ is one of the products in the Company's NanoAir™ line of products useful for Heating, Ventilation and Air Condition (HVAC), and Refrigeration uses. PolyCool's target is improving new and existing cooling tower applications. The benefits of PolyCool™ include:

  • Improved system efficiency and lower environmental impact(s)
  • Improved quality of stored water
  • Reduced need for 'new' water
  • Reduced maintenance and energy costs
  • Reduced likelihood of passing dangerous germs and viruses
  • Extending the benefits of cooling tower technology to the residential and small commercial Heating, Ventilation, and Air-Conditioning (HVAC) systems market

One of the most common uses for cooling towers is by commercial structures as a form of cooling to remove the heat created by the building's HVAC system. Cooling tower systems typically rely upon a water-based solution to gather the heat from the HVAC system, bring it to a tower, and ultimately allow the heat to escape. Once the heat is removed, the water-based solution is re-circulated into the building to take out more heat.

There are two common forms of cooling towers -- wet and dry. Wet cooling towers evaporate heated water using a tangled packing material known as "fill" to spread the heat-carrying water onto a thin film over a large surface area to speed evaporation. This technology requires expensive and ongoing maintenance costs of the systems, as well as frequent escape of the dirty water from the evaporative cooling process to the area around the evaporative cooler and into the clean water supply. By comparison, dry cooling towers use a barrier material to separate the working fluid from the air, preventing the release of water droplets into the air that can carry dangerous bacteria to humans or animals. The downside is dry units are unable to take advantage of evaporative cooling methods -- thus reducing their efficiency.

Dais' PolyCool™ is a hybrid product taking the strengths of both wet and dry cooling tower technologies and offering greater safety and efficiencies. PolyCool™ offers the performance of a wet cooling tower evaporating the water vapor through the solid Aqualyte™ nanotechnology membrane. This innovation establishes a barrier, similar to dry cooling technologies. It inhibits bacterial transmission while keeping the working fluid isolated in an otherwise closed system for increased safety, reducing the likelihood of passing dangerous germs and viruses. As the Aqualyte™ material shows reduced scaling and fouling concerns, water can contain a higher concentration of dissolved minerals, lessening the requirements for used water to be replaced thus allowing the use of recycled water sources instead of potable water.

During the coming year, the Company will work alongside select HVAC Original Equipment Manufacturers (OEMs) and key end-users needing the benefits of PolyCool's higher performing feature set to expand sales to the general cooling tower marketplace. A recent market research study published by highlighted growth opportunity within the HVAC industry citing "advances will also be propelled by rising demand for increasingly efficient HVAC systems and other types that have a higher degree of technological sophistication, as these are typically higher value systems."

"Dais is proud of PolyCool's ability to leverage the features of our Aqualyte™ nanotechnology membrane. This product addresses cooling tower safety and efficiency improvements needed in today's air quality and environmentally conscious society," said Tim Tangredi, Chief Executive Officer of Dais Analytic. "We've all followed the unfortunate spreading of legionella bacteria, the cause of Legionnaire's Disease, a deadly infection that has led to at least 12 deaths in New York and seven outside of Chicago areas. We believe PolyCool™ has the potential to significantly impact the health of people across the globe, lowering the demand for more water, improving the quality of water existing within cooling towers, and ultimately reducing maintenance costs while improving energy efficiencies."

Aqualyte™ nanomaterials and processes are used to replace energy consuming components such as motors, compressors, and more in a newer generation of air, energy, and water products. The features of the nanomaterial consume little energy and have no moving parts, allowing the targeted air, energy and water industry products using it to provide enhanced efficiencies and end-user functionality.
