Infiltration into a vacuum can lead to product contamination (for example: in the case of vacuum furnaces), downtime and reduced efficiency. Typical applications include freeze dryers, turbine seals, evaporators and distillation columns.

Ultrasounds are generated when a fluid moves from the high pressure side (ambient) through the leak to the low pressure side (vacuum vessel). Though this technique is most appropriate for mid to gross leaks the ease of ultrasonic detection makes it useful for most vacuum leak problems.

Many components of power and chemical plants, such as heat exchangers, turbine vapour circuits, freeze dryers and distillation columns, require regular monitoring for ingress leaks. Helium is sprayed over suspected leak areas and the vacuum pump exhaust is monitored for helium content. Explosion proof and radio linked versions of these portable helium leak detectors are also available.

Should you have any questions, or if you would like to discuss any of this further, then please do not hesitate to get in touch.
