How Do Dry Sprinkler Hheads Work?
forede® brand Dry sprinkler heads work by using pressurized air to keep water from entering the sprinkler system until a fire is detected. When a fire is detected, the air pressure drops and the dry valve releases, allowing water to flow through the sprinkler system and extinguish the fire.
Dry sprinkler heads are typically used in unheated areas where freezing temperatures could cause the water in a wet pipe system to freeze and damage the pipes. Instead of water being held in the pipes, dry sprinkler systems are filled with pressurized air or nitrogen, which keeps the water out until a fire is detected.
When a fire breaks out and the temperature in the room rises, the sprinkler head closest to the fire releases, allowing the air pressure to drop and the dry valve to open. This releases the pressurized air and allows water to flow through the system and onto the fire.
Dry sprinkler heads are an efficient and effective way to protect properties from fires in areas where freezing temperatures are a concern. By using pressurized air to keep water out of the system until it is needed, dry sprinkler heads help ensure that water is only used when necessary, preventing potential water damage to the property.
