T.C. Wilson Vacuum Leak Detector

The TC Wilson Vacuum Leak Detector (VLD) gives you a quick, reliable way to check heat exchanger tubes one at a time, so you can locate problem tubes without the guesswork. How the Vacuum Leak Detector Works The VLD uses compressed air instead of a separate vacuum pump to check each tube. Instructions for use: Seal the far end of the tube with a tube plug. Press the nozzle into the near end of the tube and squeeze the trigger. Compressed air will then flow through a Venturi chamber and produce a vacuum inside the tube. When the gauge shows a good vacuum level, release the trigger. Watch the gauge. A steady reading means the tube is sound. A falling reading means the tube is leaking. Why Maintenance Teams Use the VLD One person can do the job. You don't need a second worker to perform this test, which cuts labor costs on every inspection. It's fast. A typical tube takes just 6 to 8 seconds to test. (Based on a 1″ OD, 20-gauge tube that is 20 feet long.) It's easy to handle. At just 2.25 lbs, the detector is comfortable to use, and a built-in muffler keeps it quiet. It covers a wide range of tube sizes. The VLD tests tubes from 1/4″ to 3″ OD.
