From early history, mankind sought ways to reduce friction. Primitive methods ranged from sliding heavy stones on ice while building the Forbidden City, to tallow lubricated wheel axles.
Then more sophisticated mechanical engineering amplified the need to reduce friction in operating machinery, thus increasing efficiency and longevity. But with many attempts, major drawbacks rendered them commercially unsuccessful. These technologies included the use of PTFE (Polytetrafluoroethylene), with one of the lowest coefficients of friction against any solid.
In the mid-1970s, brothers Larrell and Dale Willis began developing PTFE treatment formulas. Together, the Willis’ research and development efforts produced a clear focus on problem areas and potential solutions. And beginning in the early 1980s, Owen Heatwole’s relationships with several PTFE treatment manufacturers grew to include sales, marketing and technical support.
When the Willis/Heatwole team met in the mid-1980s, they immediately recognized a potent chemistry; a wealth of experience and an entrepreneur‘s spirit combined with an eagerness to address the industrial market. So was birthed QMI, of Lakeland, Florida, where formula development grew to include hydraulic, gear and pneumatic treatments and beyond PTFE to a wide range of fuel treatments and other industrial 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.
