Leak Detection
Vacuum Leak Survey
Vacuum system leak detection using ultrasonic instruments — we've detected vacuum leaks where others have failed.
Finds leaks others have missed
Works across every vacuum application
Specialist ultrasonic technique
Recognise the Problem
Vacuum system performance has degraded, but nothing looks obviously wrong — an inward leak doesn't show the signs a pressure leak would.
You've tried locating a vacuum leak with conventional methods, or a previous provider, without success.
Your vacuum system isn't holding the level it was designed for.
Here's what that looks like in practice — what we investigate, how we assess it, and what you'd typically find:
What We Inspect
Vacuum systems used for mechanical handling, vacuum packing, degassing, and distillation.
What We Find
Leaks that are notoriously difficult to locate with conventional methods, even with high-quality equipment.
How It Helps
A well-trained technician with real vacuum-system knowledge locates leaks reliably, restoring system performance.
Our Advantage
"We have detected vacuum leaks where others have failed" — a track record built on deep ultrasonic detection experience.
Vacuum leaks have a reputation for hiding from everyone who looks for them — until someone brings the right instrument, since a small inward leak can degrade a vacuum system's performance without producing any of the obvious signs a pressure leak would.
Vacuum systems are used across a wide range of industries — power plants, steel, paper, pharma, and R&D centers — for everything from mechanical handling and vacuum packing to degassing of oils, distillation, and steel stream degassing, and each application depends on the vacuum holding at the level it was designed for.
Locating a vacuum leak is a necessary step after a vacuum is created, but it's notoriously difficult with conventional methods. Even with high-quality equipment, it takes a well-trained technician with real working knowledge of vacuum systems to do it reliably, because the physics of an inward air leak behaves differently from the outward leaks most detection methods are built for.
Using ultrasonic detection tools — the same CTRL UL101 technology behind our compressed air and gas leak surveys — Permaweld has consistently located vacuum leaks that other methods and providers missed. "We have detected vacuum leaks where others have failed" is a track record built on deep, specialized ultrasonic detection experience.
