Products Description
CA-FIRE Dry Pendent Fire Sprinkler
The dry-type pendent fire sprinkler is a high-standard, high-quality fire protection product featuring an imported German glass bulb and a metal sealing spring assembly, ensuring precise temperature response and long-term sealing reliability.
In dry pipe and pre-action sprinkler systems, conventional pendent sprinklers may suffer irreversible damage when residual water or condensation inside the sprinkler body freezes and expands at temperatures below 0°C. This can lead to cracking, leakage, and system failure.
The dry-type pendent sprinkler is specifically designed to eliminate this risk. Its sealing assembly is positioned at the top of the installation pipe, leaving the entire connection section free of water. This structural design effectively prevents freezing caused by trapped water or condensation, even in low-temperature environments.
This sprinkler is ideal for installations where sprinklers or connecting pipes are exposed to freezing conditions, or where sprinkler systems require seasonal drainage. Typical applications include cold storage facilities, unheated warehouses, parking garages, and outdoor or semi-outdoor structures.
