ESFR Pendent Sprinkler Head K22 1-inch (25mm) Threaded Model P22

The Reliable Model P22 ESFR Pendent Sprinkler is engineered for advanced fire protection systems, delivering rapid activation and heavy water discharge to directly suppress high-challenge fires in commercial and industrial facilities. Designed specifically for pendent installation in warehouses, distribution centers, and high-piled storage areas, this component provides immediate fire suppression to help minimize structural damage, limit fire spread, and eliminate the need for complex in-rack sprinkler configurations.

This suppression assembly operates in compliance with strict fire safety codes, ensuring adherence to mandated facility protection requirements governed by NFPA standards for commercial storage and fire sprinkler installations. By deploying Early Suppression Fast Response technology, the system discharges a high volume of water at lower pressures to aggressively control severe fire threats.
