Dry Type Fire Sprinkler for Cold Areas
The dry type fire sprinkler head is designed for dry pipe and preaction systems in freezing or unheated environments. A sealed inlet keeps the extension tube dry under normal conditions, preventing freezing. When activated by heat, the glass bulb ruptures, releasing water instantly to provide reliable and effective fire suppression.

CA-FIRE Dry Type Fire Sprinkler Head
The dry type fire sprinkler head is a specially designed assembly consisting of a sprinkler head, sealing mechanism, and a short extension tube. It is developed for use in dry pipe and preaction sprinkler systems, particularly in areas exposed to freezing temperatures or seasonal shutdown conditions.
Under normal conditions, a sealing device at the inlet prevents water from entering the exposed extension tube, keeping it dry and eliminating the risk of freezing. When a fire occurs, the heat-sensitive glass bulb ruptures at the rated temperature, releasing the sealing mechanism under system pressure and allowing water to discharge immediately for effective fire suppression.
This dry type sprinkler is commonly used in cold storage facilities, unheated parking garages, loading docks, outdoor canopies, and other environments where standard wet sprinkler installations may freeze.
Core Advantages
Freeze Protection Design
The dry-type structure keeps water out of the exposed tube under normal conditions, effectively preventing freezing in cold or unheated environments.
Reliable and Fast Activation
The heat-sensitive glass bulb activates accurately at the rated temperature, allowing water to discharge immediately for effective fire suppression.
Compatible with Dry & Preaction Systems
Specifically designed for dry pipe and preaction sprinkler systems, ensuring stable performance and system safety.
Flexible Installation Options
Available in pendent and upright configurations, suitable for various ceiling heights and installation requirements.
Durable and Low Maintenance
High-quality materials and a simple sealing mechanism reduce the risk of leakage and maintenance needs.

Ideal Applications
Dry-type fire sprinkler heads are especially suitable for environments where water-filled piping may freeze or where heating is not continuously available. They are widely used in cold and unheated spaces that require reliable fire protection without the risk of pipe damage caused by freezing.
Typical applications include cold storage rooms, refrigerated warehouses, and food processing facilities, where low ambient temperatures are maintained year-round. They are also ideal for unheated or partially open parking garages, loading docks, logistics platforms, and outdoor canopies exposed to seasonal cold weather.
In addition, dry-type sprinklers are commonly installed in unheated warehouses, industrial plants, stairwells, and covered outdoor areas where conventional wet sprinkler systems are not suitable. Their freeze-resistant design ensures stable operation and dependable fire protection in challenging environmental conditions.
