Objective leak test under vacuum or under atmosphere
Short cycle times
Reliable testing results in the low leakage range
Single or multi-chamber testing system
Fully automated testing process
No parts drying required
Helium recovery or gas mixing systems
Article recording for other product variants
Cycle time reduction through additional test chamber
Effective cycle time: 12 s
Capacity: 300 parts / h
Test gas: 10% helium / 90% air
Leak rate: 4,8 . 10-5 mbar . l/s (with 10% helium)
LH₂ stored in low-pressure cryogenic tanks.
Requires strong insulation due to –253 °C boiling point.
Any heat causes LH₂ to gasify and raise pressure.
Tanks must have very low leakage rates.
Components tested using helium leak testing.
