Products Description
PT Series Fixed Foam Nozzle
Engineered for tunnels, underground areas, and other high-risk enclosed spaces, the CA-FIRE PT Series Fixed Foam Nozzle provides reliable foam distribution through a fixed piping network for fast fire control and large-area coverage.
The nozzle delivers a stable foam blanket that quickly covers the protected surface, helping suppress flames, reduce heat radiation, and isolate combustible materials from oxygen to minimize the risk of fire escalation.
With optimized discharge design and durable construction, the PT Series Tunnel Foam Nozzle offers dependable protection for tunnels, underground facilities, parking areas, industrial plants, and other critical locations where effective fixed foam fire suppression is required.
What It Is
Fixed Foam Discharge Device for Tunnel Fire Protection
The PT Series Fixed Foam Nozzle is an open-type foam discharge device designed for use in fixed foam fire suppression systems installed in tunnels, underground spaces, and other enclosed high-risk environments.
When foam solution reaches the nozzle, the internal flow structure optimizes foam expansion and controls the discharge pattern, creating a uniform foam spray coverage over the protected area. This design helps ensure effective distribution while reducing the possibility of insufficient coverage or uneven foam accumulation.
Unlike conventional water sprinkler heads, the PT Series is specifically developed to produce a stable and durable foam blanket that adheres to the protected surface. The foam layer helps quickly control flammable liquid fires, suppress flame development, reduce heat transfer, and provide continuous protection against re-ignition.
The nozzle can be easily integrated with complete foam fire suppression systems, including foam proportioning units, foam pumps, and deluge valve assemblies. It is suitable for both new fire protection projects and system upgrades requiring reliable fixed foam discharge solutions.
How It Works
1. Foam System Activation and Solution Transfer
When a fire is detected, the fixed foam suppression system activates and delivers foam solution through the connected pipeline network. The properly proportioned mixture of water and foam concentrate is supplied to the PT Series Fixed Foam Nozzle, ensuring a continuous and reliable discharge process.
2. Controlled Foam Generation and Distribution
The PT Series nozzle is designed to regulate the flow of foam solution and create a consistent discharge pattern. Through optimized nozzle geometry, the foam expands effectively and spreads evenly across the target area, providing comprehensive coverage in tunnels and other enclosed spaces.
3. Formation of Protective Foam Blanket
After discharge, the expanded foam rapidly covers the fire source and surrounding surfaces, creating a stable protective layer. This foam blanket suppresses combustion by limiting oxygen contact, cooling heated surfaces, and reducing the possibility of fire re-ignition.
4. Continuous Hazard Control
By maintaining foam coverage over the protected area, the system helps control fire development and reduce the impact of heat and smoke. The PT Series nozzle provides dependable protection for tunnels, underground facilities, industrial areas, and other locations where rapid fire suppression is essential.
Key Features
Wide-Area Foam Coverage
Designed for tunnels and large enclosed spaces, the PT Series Fixed Foam Nozzle provides effective foam distribution across extensive protection areas. Its optimized coverage performance helps reduce installation points while maintaining reliable fire suppression capability throughout the protected zone.
Rapid Fire Response
Installed as part of a fixed foam suppression system, the nozzle can release foam immediately when the system is activated. Fast foam application helps control fires during the early stage, limiting flame spread, heat release, and potential damage to surrounding structures.
Optimized Foam Discharge Performance
The PT Series features a specially designed internal flow structure that supports stable foam formation and consistent spray patterns. The discharge characteristics are optimized for tunnel environments, ensuring efficient foam delivery in long passages and enclosed areas.
Durable Construction for Harsh Environments
Manufactured with high-quality corrosion-resistant materials, the nozzle is built to withstand demanding conditions such as moisture, dust, chemicals, and industrial exposure. Its robust design ensures long-term reliability with minimal maintenance requirements.
Easy Integration with Foam Systems
The PT Series is designed for convenient connection with complete foam fire protection systems, including foam tanks, proportioning equipment, foam pumps, and deluge valve systems. Its compatibility simplifies system installation, commissioning, and future maintenance.
