History of Cold-Plus®

Early Days


Cold-Plus™ is a proprietary inert nanoparticle-lubricant for use in the compressors in all HVAC and refrigeration systems. This PTFE nanotechnology was originally developed by DuPont to increase laminar flow and reduce blood clotting in veins and arteries during invasive surgical procedures. Due to the similarities between a biological heart and a mechanical compressor, the proprietary component, PTFE (Polytetrafluoroethylene) , was then added to an industrial lubricant so that it could create similar results in mechanical systems. The resulting compound is Cold-Plus™, which has been proven to reduce the energy consumption of HVAC/refrigeration systems and extend the lifespan of the unit. Cold-Plus™ is the only SRA (Synthetic Refrigerant Additive) with PTFE and is chemically inert and meets OSHA standards for handling safety. Its effect on increasing laminar flow, has been successfully tested at the National Renewable Energy Laboratory (NREL) in Golden Colorado, where it was verified that a 14% increase in laminar flow was achieved when using Cold-Plus™. These tests were conducted using a 20-ton Carrier cooling unit from Walmart. The effectiveness of Cold-Plus™ in increasing HVAC performance and increasing the system’s lifespan have also been statistically verified by Dr. Elizabeth Clarkson, the Chief Statistician and Senior Research Engineer of the National Center for Advanced Materials Performance (NCAMP) in Wichita, Kansas. Cold-Plus™ has been proven to reduce the electrical consumption of compressors by up to 30% in some older units. Cold-Plus™ has also been successfully implemented and proven in over 14,000 homes, businesses, automobiles, industrial construction equipment, and the professional racing industry over the last 10 years.strial products. 


After successfully developing many PTFE based and other products and growing QMI, they decided to sell to ITW in 2006. Larrell and Dale’s formula developments also included PTFE based technology for use internally in air conditioning and refrigeration systems. This turned into a very difficult task with the multitude of refrigerants and lubricating oils used in the compressors and the need to achieve compatibility with all combinations (except ammonia). 

The original concept focused on reduced friction in the compressor, and thus reduced energy use, and the removal of oil fouling plus slippery PTFE treatment to prevent the return of oil fouling. Further, the Willis brother developed a combination of micro/nanopolymers that remain suspended in the system to greatly enhance thermodynamics – both heat and cold transfer. It became evident that there was much more involved than just decreasing friction. 

Early testing gave results on older equipment much greater than anticipated. Further investigation pointed the way toward heat transfer increases and thus significantly increased efficiency. 

One of the most important of these became the understanding of “oil-fouling” that occurs when lubricating oil begins to break down and deposit oil particles on metal surfaces within the system. This accumulation reduces the heat transfer ability of the system, and efficiency becomes more detrimental as the unit ages.

Many years of testing revealed a series of improvements that, when combined, today allows a significant increase in the efficiency of the unit. 

Thus we offer you the many benefits of Cold-Plus® A/C & Refrigeration Treatment.
