This compact service unit has been specially designed for very small gas quantities and is perfectly suited for applications such as SF6 gas handling on medical devices, electron microscopes or medium voltage components. The device includes all functions required for professional and emission-free SF6 gas handling such as: gas recovery down to < 10 mbar, purification during the recovery and filling process, gaseous storage in an internal vessel or external pressure tank, evacuation of air to < 10 mbar with automatic switch-off as well as automatic filling of the gas compartment until reaching the desired final pressure. All functions run fully automated and can be easily set on the coloured touch panel.
