Suitability

The multi-channel gas detector system FlexADOS914 MED continuously monitors the ambient air and provides an early warning of harmful, explosive and non-flammable gases and vapours. The evaluation unit has been equipped with a robust cabinet to resist increased mechanical strains as they may occur in the maritime sector. Moreover, the evaluation unit disposes of the class certificate DNV-GL and fulfills the requirements of the Marine Equipment Directive 2014/90/EU (marking: MED wheel mark). Together with the GTR 210 gas transmitter family, FlexADOS 914 MED achieves safety integrity level SIL1 and can be used for primary explosion protection.

Areas of application

Explosion protection on ships with LNG drives, LPG drives and LFL drives
