1-800-345-3476 I 15 HeliumTesting Services Trained in all aspects of tracer gas leak detection Conco technicians can use a Helium Mass Spectrometer System to inspect for condenser air in-leakage andor condenser tube leakage while the unit is running. When the unit is down they can test main generators and stator water systems for leakage. Unsurpassed in experience Conco technicians have mastered the art of leak detection. In addition to field services complete Helium Mass Spectrometer Systems and in-house training are available see pages 28 to 29. SF6 Testing Services SF6 has a detectible concentration of one part per ten billion versus heliums one part per million above background level.The ultra sensitive nature of this tracer gas makes it ideal for finding very small leaks within condenser tubes. Conco pioneered the use of SF6 for power generation leak detection in 1978 and is the only company to manufacture a continuous sampling SF6 analyzer Our Fluorotracer analyzer takes full advantage of the detectible concentration of SF6 and can also be used with our handheld SF6-Pak to perform air in-leakage surveys making it an extremely versatile system. For complete SF6 Systems and in-house training see pages 28 to 29.
