Helium is widely used as an excellent tracer gas in the leak detection process. However, its increased costs – and their negative impact on profit margins – are a huge concern in today’s production environments.

Hefei Young Vacuum has developed a proven concept to recover helium for low-, mid- and high-pressure applications. The permanent system control visualizes the values and ensures that the ratio of helium to nitrogen remains constant throughout the testing process, eliminating contamination of the surrounding production area.

1. The high-pressure gas detects large leaks, and at the same time completes the strength detection；

2. Vacuum box vacuuming and background suppression；

3. The workpiece is evacuated and filled with helium；

4. Helium Mass Spectrometer Leak detects small leaks；

5. Helium Recovery.
