Adjustment device H2-Z002R21

Product overview
The ServiceCart H2 supports workshop employees in work on hydrogen systems in vehicles. The device can perform service functions fully automatically.

Main functions

• Depressurisation of the hydrogen system (low-pressure system max. 60 bar)
• Inertisation of the system with nitrogen
• Residual gas measurement to confirm that the system is hydrogen-free
• Purging with forming gas for subsequent leak tests
• Leak tests to detect leaks after service

Application limits
The device can be used for hydrogen systems up to a pressure of max. 60 bar. Line systems with higher pressure must be isolated by shut-off devices in the vehicle.
