Intertec Fire Shelter

1 Application

In the event of a fire, emergency “shut down” (ESD)

valves and their actuators must be protected against

heat exposure in chemical and petrochemical plants.

In an emergency, the actuators must remain operable

for a minimum of 15 minutes after the outbreak of a

fire. More stringent requirements such as 30, 60 min.,

or higher are also possible.

For these applications INTERTEC has developed a

patented protective shelter system fully tested by a

certified 3rd party agency to meet UL 1709.
