Vaccum Chamber Leak Testing

Finding leaks on large vacuum chambers using a helium leak detector is fast, efficient and cost-effective.

Finding leaks on large vacuum chambers using a helium leak detector is fast, efficient, and cost-effective. The proper selection of a leak detector, the connection of the detector to the vacuum system, and the appropriate use of helium tracer gas are fundamental to a successful leak test.

Typically, large vacuum chambers use a high vacuum pump (turbo or diffusion) backed by a roots-type blower and mechanical pump. This method provides the fastest response and cleanup.

Helium Leak Testing for Vacuum Chambers

The behavior of most large vacuum systems evolves over time. Chambers used for production processes will almost inevitably develop leaks that can affect product quality, and damage internal components. Leaks can develop in multiple locations including; valves, feedthroughs, door seals, and so forth.

Large leaks in a vacuum system are usually obvious: the chamber will not pump down as expected, or it will bottom out at a pressure well above its typical base pressure. Small leaks, however, are more difficult to troubleshoot, and often go undetected, as the pumping system can easily overcome the gas load of the leak. Even if the vacuum gauges still read appropriate levels, the leak may show up as a contamination inside the chamber.
