About linear pneumatic heat 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

Efficient Fire Detection & Response

Our pneumatic heat detection tubes deliver rapid identification and immediate activation upon sensing heat at specified burst temperatures (68C, 93C, 110C, or custom). This quick response ensures fire threats are addressed before escalation, offering enhanced protection for sensitive environments such as server rooms, manufacturing plants, and warehouses.


Versatile & Robust Construction

Manufactured from specialty engineered polymers, the tubes provide outstanding flexibility and resilience against UV, oil, and chemical exposure. The minimum bend radius of 50 mm enables easy routing around obstacles, while the red color offers clear visibility. The system's durability supports a service life of up to 10 years under normal conditions.


Seamless Integration and Compliance

Designed for simplicity, these tubes are compatible with a variety of clean agent, CO2, or ABC powder suppression systems. Installation is straightforward, whether mounted on surfaces or integrated into existing infrastructures. The solution is fully compliant with EN54 and, upon request, IS:15683 standards, meeting strict international safety requirements.
