What is the main function of a dry pipe system in a fire sprinkler setup?

A dry pipe system in a fire sprinkler setup is specifically designed to keep the pipes empty of water until the system is activated by a fire event. This is essential in applications where there is a risk of freezing, as having water in the pipes could lead to ice formation and potential pipe bursts. Thus, the primary function of the dry pipe system is to maintain a dry environment until activation, ensuring that the sprinklers will function correctly when needed while reducing the risk of damage due to freezing temperatures.

In situations where immediate water flow is necessary, a different type of system, such as a wet pipe system, is used, which keeps water constantly in the pipes. Minimizing water pressure and facilitating faster installation are not inherent functions of a dry pipe system. The focus is instead on maintaining a state of readiness while protecting the integrity of the infrastructure against conditions that could compromise the system’s operation.
