Testing Heavy GIS Enclosures? Pinpoint Every Micro-Leak with Confidence.
When manufacturing bulky high-voltage GIS (Gas-Insulated Switchgear) housings, fitting massive, odd-shaped enclosures into a giant vacuum chamber isn’t always practical. Yet, ensuring annual gas leakage stays below 0.01% to 0.5% is non-negotiable—a single micro-fissure at a flange weld can delay an entire substation commissioning.
Our Positive Pressure Helium Sniffing & Recovery System is built for real shop-floor challenges.
Instead of guessing, your technician pressurizes the GIS component with helium (up to 0.8 MPa) and uses a handheld sniffing gun to trace seams and joints. The system instantly pinpoints the exact leak location, taking the guesswork out of troubleshooting large workpieces.
Why factory engineers rely on this setup:
-
Stop Wasting Helium: The automated recovery unit evacuates and recycles test gas, drastically cutting your daily operating expenses.
-
Safe & Simple Operation: Smart PLC touch-screen control equipped with electrical interlocking and audio-visual safety alarms.
-
Tailored for Your Shop Floor: Fully customized piping, gas connections, and recovery carts built around your factory layout.
