Elfab bursts into orbit

Elfab made a vital contribution to the recent successful launch of the Ariane-503 rocket. Elfab designed the bursting discs for use in the launcher igniters: used as pressure switches, they control the ignition of the hydrogen/oxygen mixture.

Bursting discs were chosen for the task as they have proven reliability and are extremely responsive to very slight changes in pressure, making them ideal as ultrafast pressure switching devices.
