Dry Pipe Sprinkler System
Unlike wet sprinkler systems, dry pipe sprinklers aren’t full of water but instead are pressurised with air. The pressure from the air holds a valve closed containing the behind it, when a sprinkler head detects a rise in heat the system activates releasing the air and subsequently the water.
Although, the time it takes the water to leave the open valve and travel down the pipes to the sprinkler heads is about a minute’s delay, however for buildings in colder climates where the water in the piping system would typically freeze, a dry pipe system is ideal.
