Wet Sprinkler System 

A wet pipe sprinkler system is the most common and reliable type of fire suppression system used in commercial buildings. It maintains pressurized water in the pipes at all times, allowing for an immediate response when a fire is detected.

When heat activates a sprinkler head, water is released instantly and only from the affected area, helping to control or extinguish the fire before it spreads. Wet systems are ideal for environments where temperatures remain above freezing year-round.

Why Choose a Wet System?

• Fast response time
• Simple design with fewer components
• Low maintenance requirements
• Proven effectiveness in a wide range of facilities

Dry Sprinkler System

A dry pipe sprinkler system is designed for environments where freezing temperatures could damage traditional wet systems. Instead of water, the pipes are filled with pressurized air or nitrogen, which holds a remote valve—known as a dry pipe valve—in a closed position.

When a fire activates a sprinkler head, the air pressure drops, causing the valve to open and allowing water to flow into the pipes and out through the activated sprinkler. This design prevents water from sitting in the pipes, making it ideal for unheated warehouses, parking garages, and outdoor structures.

Key Benefits:

• Prevents pipe damage in freezing conditions
• Reliable fire suppression in cold environments
• Complies with NFPA standards for temperature-sensitive areas

Pre-Action Sprinkler System

A pre-action sprinkler system is a specialized type of dry system designed to provide an extra layer of protection against accidental water discharge. It uses a pre-action valve that remains closed until triggered by a fire detection event, such as heat, smoke, or flame.

Once the system detects a fire, the valve opens to allow water into the pipes—but water is only released through sprinkler heads that are individually activated by heat. This two-step process makes pre-action systems ideal for environments where water damage must be avoided, such as data centers, museums, and archives.

Key Advantages:

• Prevents accidental discharge
• Ideal for high-value or sensitive environments
• Combines detection and suppression for added control
• Compatible with advanced fire detection technologies

Deluge Sprinkler System

A deluge sprinkler system is designed for high-hazard environments where rapid fire spread is a serious concern. Unlike other systems, all sprinkler heads are open and activated simultaneously when the system detects a fire.

Once triggered by a connected detection system (such as heat or flame sensors), the deluge valve opens, releasing a large volume of water across the entire protected area. This aggressive response is ideal for facilities handling flammable liquids, chemicals, or explosive materials, such as industrial plants, aircraft hangars, and power generation stations.

Key Features:

• Immediate, full-area water discharge
• Requires separate detection system to activate
• Ideal for high-risk, high-value environments
• Provides maximum fire suppression coverage
