About Linear Pneumatic Heat Detection Tube

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

Exceptional Fire Detection Performance

This pneumatic heat detection tube offers immediate response when the temperature threshold is exceeded, ensuring rapid fire detection and activation of suppression. Its linear sensing capability enables comprehensive coverage, customized to the layout of each protected area, from electrical panels to vehicles and storage spaces.


Flexible and Versatile Application

Designed for flexible routing and integration, the 6mm diameter tube can be surface-mounted or built directly into equipment. Its minimum 50 mm bending radius and availability in various lengths allow seamless adaptation to unique site requirements, maximizing protection where it matters most.


Long-Lasting and Maintenance-Free Protection

With its UV-resistant coating and specialized polymer blend, the tube boasts a lifespan of over 10 years under normal conditions. It operates automatically without electrical power or routine maintenance, reducing downtime and ensuring continuous fire safety in sensitive or challenging environments.
