How Fluorescent Dyes Benefit Leak Detection Procedures in Air Conditioning and Refrigeration Systems

Have you recently looked for leaks in air conditioners or refrigeration systems? Maybe you used a bubble solution. What is a bubble solution? This is one of the most commonly used leak detection methods in the HVAC industry. It is effective to spray the soap solution on a suspicious surface until foam comes out. This bubble indicates the location of the leak. It is very old, is not it? Although this approach is cost effective in advance, in the long term its inaccuracy will ultimately lead to system failures that can not achieve maximum efficiency, high refrigerant exchange costs, food corruption and customer callbacks . This time consuming exercise caused engineers to spend too much time on their jobs. This also makes it difficult to find small leaks, especially with a windy outdoor unit.

This is a method of injecting a small amount of fluorescent dye and circulating it to the operating system. The dye / refrigerant mixture leaks and gathers at all leak locations. Then use a leak detection lamp to scan the system and emit green or yellow fluorescence so that all leaks are easy to find it

Do not you want to wait for dye circulation before going to work? Well, this method is perfect as part of a comprehensive maintenance program in which dye is being added to the system before the problem occurs. During periodic maintenance or service calls, you can use a leak detection flashlight or light to quickly scan system leaks. Fluorescence may occur if there is a leak. Even minimum leakage can be easily judged.

AR - GLO ® fluorescent dyes are OEM certified by major compressors, AC & R equipment, lubricants, and refrigerant manufacturers. Currently it is used in more than 50 million AC & R systems worldwide.

• Fluorescence leak detection. This method requires the addition of fluorescent dye to the air conditioning or refrigeration system. The dye then mixes with the lubricant and circulates with the refrigerant throughout the system. As long as the refrigerant leaks, the dye will leak out. When using an ultraviolet (UV) or blue light scanning system, the dye emits a light yellowish green color indicating the location of the leak. When using fluorescence leak detection it is best to choose UV or blue light to produce high intensity output. The greater the light intensity, the more dyestuff will emit light and it will be easier to find the leak. Depending on the light bulb, the emitting dye may be visible up to 20 feet. This allows the technician to find a leak in the overhead system. In addition, since the dye remains in the system until the lubricant changes, fluorescence leakage detection can be used for preventive maintenance.

This is a method of injecting a small amount of fluorescent dye and circulating it to the operating system. The dye / refrigerant mixture leaks and gathers at all leak locations. After that, the system is scanned with leak detection light and all leaks emit green or yellow fluorescence, making discovery easier. Do not you want to wait for dye circulation before going to work?

How fluorescent dyes are useful for leak detection procedures in air conditioning and refrigeration systems

This refrigerant leak detection method is more complicated and was developed to discover leakage of automatic transmissions in the automobile industry. Here, the system suspected of leakage is filled with special fluorescent dye. The dye mixes with the oil and the mixture circulates through the refrigerant in the system. As it escapes through the leakage, you will see a glow under UV light
