A “dry” fire sprinkler system is used where a freeze risk may arise. The dry system is constantly charged with compressed air, which holds the dry-pipe valve in the closed position. When a fire sprinkler head is activated, the air pressure is lost, the valve opens and water flows into the system and on to the fire.
A dry fire sprinkler system is commonly installed in areas where the system piping is exposed to temperatures at or below 40 degrees F.
