Several years ago Texas coil manufacturer Coil Specialist, Inc. made the bold leap away from traditional water leak testing of their products in favor of modern science and technology.
CSI began in 2000, and by 2005 they had outgrown the old fashioned “dunking” method of leak detection. Gerry Averett, President of CSI and an industry veteran, knew that other, superior technology existed. He contacted VTech and after a field equipment trial, he decided to invest in its first VTech 75 combined pressure decay, tracer gas filling and hydrogen sniffing leak test system.
Water is the natural enemy of refrigeration coils. A Pressure Decay leak test with nitrogen or dry air will achieve much better results without water, while tracer gas leak detection with helium or diluted hydrogen will locate very small leaks in a matter of seconds (as low as 0.03 oz of refrigerant/year).
Today, multiple VTech 75 pressure decay and hydrogen sniffing machines operate at CSI alongside a VTech MasSpec automatic helium outside-in system. To compare the CSI of 10 years ago to today, one would barely resemble the other. The water tanks and drying ovens are gone. The savings on natural gas alone paid for their first machine. They can confidently say that they do not ship leaky coils.
In the words of Gerry Averett, President of CSI:
“CSI has invested capital dollars in top-of-the line equipment and employee development to reach for our future. These men and women will take CSI to all new levels over the coming years and will have a great impact on this industry, with use of new technology such as VTech’s.”
