Detecting refrigerant leaks using fluorescent dye

To help air-conditioning and refrigeration engineers wanting to move over to fluorescent leak detection, Spectroline offers two all-in-one starter kits. The packs are distributed in the UK by Advanced Engineering and include a choice of lamp. Optimax Junior can fit into a top pocket and is powered by three AA batteries that will power the LED light source for over half a day continuously. The Optimax Pro can pinpoint a leak up to 6 m away. A small shot of Ar-Glo fluorescent dye is added to the system while it is still running and allowed to circulate. Escaping fluid carries the dye with it, which glows a brilliant yellow green under an Optimax lamp. Leaks as small as 3 g a year can be seen. Once repairs have been made, the kit’s antiGlo spray removes the dye from the leak site, so later checks will confirm if the work was successful. The dye can be left in the system indefinitely.
