Packing & Delivery

 The fire dry sprinkler is designed for use in dry pipe systems, primarily to prevent water from freezing in pipes in cold environments. It remains closed until a fire triggers the system: when heat activates the sprinkler's temperature-sensitive element (e.g., a glass bulb or fusible link), the dry pipe valve opens, allowing compressed air to escape and water to flow into the pipes and through the sprinkler head. This delays water entry into the system until needed, avoiding pipe bursts from freezing. Ideal for unheated areas like warehouses, garages, or outdoor facilities, it ensures rapid response to fires while protecting the piping infrastructure. The dry sprinkler combines freeze protection with reliable fire suppression, maintaining system integrity in low-temperature settings and minimizing false activation risks
