Steam Curtains

“A water / steam curtain system uses an array of spray nozzles to create a barrier of water to contain a fire inside a small area.  The nozzles can be mounted to shoot water either upwards or downwards.  The goal of a water / steam curtain is to provide exposure protection or to stop the flow of flammable vapors from migration into a hazardous area.”

A steam curtain is used as a permanent installation to contain and disperse leaks of flammable gas heavier than air.
