High rise sprinkler systems are comprised of many working parts: a main water storage tank, a high-efficiency pump system, and a network of pipes fitted with sprinkler heads. In a wet pipe system, water remains in the lines for an instantaneous delivery of water. In a dry pipe system, the lines are filled with air instead of water. Upon activation, the air rapidly decompresses allowing water to flood the lines. Additionally, depending on the application, sprinkler systems may have nozzle type or deluge type sprinkler heads. Nozzle type heads allow for greater control over the direction of spray providing targeted fire suppression. Deluge type heads are designed to rapidly deliver water and maximize surface coverage.
