Wet Pipe Sprinkler Systems:

• Always Filled with Water: In wet pipe systems, the pipes are constantly filled with water. When a fire is detected, the heat causes the sprinkler head to activate, releasing water immediately.
• Commonly Used: This is the most common type of sprinkler system due to its reliability and simplicity. It's suitable for environments where temperatures are consistently above freezing.
• Applications: Ideal for office buildings, schools, and residential properties.

Dry Pipe Sprinkler Systems:

• Filled with Pressurized Air or Nitrogen: In dry pipe systems, the pipes are filled with pressurized air or nitrogen. When a sprinkler head is activated, the air is released, allowing water to flow through the pipes and out of the sprinkler heads.
• Used in Freezing Conditions: These systems are used in areas where pipes might be exposed to freezing temperatures, such as in unheated warehouses or parking garages.
• Delayed Response: There is a slight delay in water discharge compared to wet pipe systems, but they prevent the risk of frozen pipes.
