Dry Pipe Sprinkler System

Reliable Fire Protection for Cold Environments

Dry pipe sprinkler systems are specifically designed for environments exposed to freezing temperatures. Instead of water, the piping network is filled with pressurized air or nitrogen, preventing the system from freezing and becoming inoperative in cold conditions.

When a fire is detected, the air is released from the pipes, allowing the main valve to open and water to flow into the system. Once the sprinkler heads activate, water is discharged directly onto the fire area to achieve effective suppression.

Advantages and Application Areas

Dry pipe sprinkler systems are ideal for:

• Cold storage facilities,

• Open or semi-open car parks,

• Unheated warehouses,

• Outdoor pipelines or exposed installations.

By keeping the piping system dry until activation, the system eliminates the risk of freezing and provides reliable performance in harsh environments.

Operating Principle and Technical Features

• The pipes are pressurized with air or nitrogen.

• When heat from a fire triggers the sprinklers, the air is expelled from the system.

• The deluge valve opens, allowing water to enter and discharge through the activated sprinkler heads.

Compared to wet pipe systems, dry pipe systems have a slightly longer response time, as water must travel through the piping before discharge. However, this minor delay is outweighed by the system’s superior resistance to freezing and reliability in cold zones.
