Products Description

Deluge Fire Sprinkler Wet Alarm Sprinkler
The Deluge Fire Sprinkler is designed for rapid and large-volume water discharge in high-hazard fire protection systems. Unlike standard sprinklers, deluge sprinklers remain open and only activate when the connected deluge valve is triggered, delivering water immediately across multiple sprinklers simultaneously. This makes them ideal for high-risk areas such as chemical plants, oil & gas facilities, warehouses, and industrial plants where fast fire suppression is critical.
Constructed from high-quality corrosion-resistant materials, the deluge sprinkler ensures durability and reliable performance under extreme conditions. Its design supports high flow rates and wide coverage, enabling efficient fire control over large areas. The sprinkler is compatible with standard fire protection piping and system components, allowing easy integration into existing networks. With proper installation and maintenance, the deluge sprinkler provides fast, dependable, and compliant fire suppression, protecting personnel, property, and critical assets.
