The cold vent stacks (cold flare systems / vent systems) designed and manufactured by S.T.I.T.I. can discharge the gas of a section of a plant, for the needs of maintenance and emergency. On the normal operating status, the cold vent stack has not gas in it; only when the depressurization system of the plant operates the gas is discharged through the cold vent stack (cold flare system) at atmospheric pressure.
The cold vent stack is supplied equipped with a system of detection and extinction (extinguishing) fire with CO2 or other system. S.T.I.T.I. is able to supply cold vent stacks for any operating condition and code/regulations (also for hydrogen).
