Wet Pipe Systems
The wet pipe system is the simplest and most common type of fire sprinkler installation. Wet systems are frequently installed in factories, warehouses, and office buildings where the
potential for freezing does not exist. A wet pipe system riser can employ a check valve along with an electric water flow indicator and electric alarm, or for installations requiring a
mechanical alarm, we offer an alarm check valve and water motor alarm.
Dry Pipe Systems
|
Dry Pipe Systems are frequently installed in areas subject to freezing temperatures, such as unheated storage areas and loading docks. System operation is similar to Wet Pipe Systems,
except that the system piping is charged with compressed air or nitrogen instead of water. The entire system is designed to permit quick, easy maintenance and constructed so it rarely
needs any. All components are fast acting, rugged, and durable enough to provide long years of dependable operation.
Preaction Systems (Single-Interlocked)
Preaction Systems are most frequently used to protect against accidental water discharge, or to speed the action of large dry pipe systems. Common installations include computer rooms,
process control rooms, libraries, and freezers. Often, a Preaction System is specified to replace a gas- based extinguishing system. The Single-Interlocked Preaction System requires
activation of the detection system before allowing water to flow into the closed sprinkler system piping. This helps prevent unwanted water flow when a pipe or sprinkler is accidentally
broken.
