What is a Dry Sprinkler Head

forede® brand A dry sprinkler head is a specialized type of fire sprinkler used in dry pipe fire sprinkler systems. Unlike standard wet sprinkler heads, which are constantly filled with water, dry sprinkler heads are designed to operate in environments where water cannot be stored in the piping due to the risk of freezing or other environmental factors.

How It Works:
The sprinkler head is installed in a dry pipe system, which is pressurized with air or nitrogen.

When a fire raises the temperature to a specific threshold, the heat-sensitive element in the sprinkler head activates.

The air pressure in the system drops, triggering the dry pipe valve to open.

Water flows into the piping and discharges through the activated sprinkler head to suppress the fire.

Advantages of Dry Sprinkler Heads:
Freeze Protection: Ideal for cold environments where water in the pipes could freeze and cause damage.

Corrosion Resistance: Since the piping is dry, there is less risk of corrosion compared to wet systems.

Versatility: Can be used in a variety of challenging environments.

Disadvantages:
Slower Response Time: Dry systems take slightly longer to deliver water compared to wet systems because the air must first be released before water can flow.

Higher Maintenance: Dry systems require regular maintenance to ensure the air pressure is maintained and the system is functioning properly.
