SIS & Emergency Shutdown Systems are used across a wide range of industries and offer personnel, asset and environmental protection by means of instantaneous, fail safe, plant immobilisation.
SIS is arguably the most widely used safety related application in the process industry. By monitoring safety critical field instrumentation the SIS provides automatic preventative action in the case of unsafe operational parameter deviations and ensures rapid isolation if loss of containment occurs.
A series of pre-engineered functions will then bring the facility back into full operation once the cause of the shutdown has been determined and dealt with.
