A Cpvc Dry Pipe Sprinkler System is a closed-loop fire sprinkler system that uses compressed air to activate sprinkler heads within an enclosed piping network. The pipes are filled with pressurized air, which holds back the flow of water until a fire or smoke detection system triggers the release of the air. When the air pressure drops, water begins to flow through the piping network and activates the appropriate sprinkler heads for suppression of the fire. This type of system provides superior reliability, ensuring that each sprinkler head is activated when necessary.
