The combined technologies from
Vibra-Sil can make a CITADEL unit self-sufficient in power, air supply, fuel and stand-alone functionality.

Air supply, temperature control, filtration and power and lighting are but a few of the features that can be built into a CITADEL to offer the required degree of autonomy.

From self-powered emergency data backup  to live-in communications centers, CITADEL can provide the required degree of independence.
