About Fire Detection Tube Suppliers

Linear Pneumatic Heat Detection Tube system is a good option for small electrical, server, DNS, UPS, battery, or network rooms where you want automatic fire detection and direct suppression without complex electronic detectors.

What It Is

A heat-sensitive pneumatic tube is installed around protected equipment.
When temperature reaches a preset level (typically 68C110C depending on tube type), the tube bursts at the hottest point and triggers fire suppression.

Commonly used with:

• FM-200
• Novec 1230
• CO2 Fire Suppression System
• Dry chemical systems

How It Works

Direct Release System

1. Detection tube installed above/inside racks or panels
2. Fire heats tube
3. Tube ruptures at hottest point
4. Suppression agent discharges directly at fire source

Best for:

• Electrical cabinets
• Server racks
• Battery cabinets
• Small DNS/network rooms

---

Indirect Release System

1. Tube senses heat
2. Pressure drop activates valve
3. Entire room suppression system discharges

Best for:

• Full room protection
• Data/server rooms
• Telecom rooms

---

Advantages

• No electricity needed for detection
• Very fast localized detection
• Low maintenance
• Cost-effective for small rooms
• Works during power failure
• Easy retrofit in existing server rooms

---

Typical Installation in DNS / Server Room

Detection tube routing:

• Above server racks
• Around UPS panels
• Cable trays
• PDU panels
• Network switches

Suppression cylinders:

• Wall-mounted outside room preferred
• Connected to nozzles or direct tube release

---

Important Design Considerations

1. Choose Correct Agent

For occupied IT rooms:

• Preferred:
  • Novec 1230
  • FM-200
• Avoid total flooding CO in occupied rooms

---

2. Room Sealing

For total flooding systems:

• Door seals required
• False ceiling/floor leakage checked
• Hold time usually 10 minutes

---

3. Standards

Common standards:

• NFPA NFPA 72
• NFPA NFPA 2001
• ISO standards
• Local fire authority requirements

---

Best Use Cases

Excellent for:

• Small DNS rooms
• Telecom shelters
• UPS rooms
• Electrical panels
• ATM machines
• CNC/electrical cabinets

Less suitable for:

• Very large data centers
• Open industrial halls
• Areas with high airflow unless engineered properly

Typical Small DNS Room Solution

Example:

• 1030 m room
• Detection tube around racks
• 25 kg clean agent cylinder
• Manual release + abort switch
• Alarm integration

---

If you provide:

• Room dimensions
• Number of racks
• Ceiling height
• UPS/battery presence

I can help you with:

• Basic suppression sizing
• Tube routing layout
• Cylinder capacity estimate
• Single-line schematic
• BOQ/material list
• Typical installation drawing

Flexible, Customizable Fire Detection

This linear pneumatic detection tube is adaptable for various applications, including wall-mount, equipment-mount, and cabinet-mount installations. With customizable diameters (6 mm, 8 mm, 12 mm) and flexible routing, it fits different suppression scenarios, offering easy installation in tight spaces or complex layouts. Its high-grade polymer coating ensures protection against UV rays and corrosion, making it suitable for challenging environments.


Engineered for Safety and Compliance

Built to meet NFPA and global fire safety standards, the fire detection tube is pre-engineered for specific activation temperatures-68C, 93C, 120C, or as specified-to identify and suppress fires in their early stages. With a burst pressure of over 900 psi and a recommended storage temperature below 30C, the tube boasts a shelf life of at least five years under optimal conditions.
