LINEAR FIRE DETECTION TUBES

LINEAR FIRE DETECTION TUBES

AutoFireX® Fire Detection Tubes are Linear Pneumatic Heat Detection tubes specifically manufactured and designed for the use in fire suppression systems for fire detection. It responds to combination of heat and radiant energy that generally accompanies a fire.

The pressurised Fire Detection tube when exposed to fire/radiating heat from fire, is designed to rupture due to flame impingement, at specific temperatures at any point throughout its length, thereby releasing the pressure and initiate the release of the suppressant from connected valve and operate any other pressure operated signalling device interfaced with the system. The AutoFireX® Detection Tube is used as a nonelectrical detection device.

KEY FEATURES

  • Special Formulated material designed to function in Harsh and reactive environments.
  • Formulation designed to prevent surface damage when exposed to or installed on Galvanised metal/equipment’s.
  • Special Formulation prevents gradual permeation of pressurising agent over period of time, adding to its 100% reliability.
  • Non-Destructive,Tested to withstand pressure max up to 140 Bar.
  • UV Protected, available in 3 temperature options.
  • Low moisture and water absorption ratios.
  • Chemically resistive to most common chemicals.
  • Compatible with all Inert, Low pressure and High-Pressure Agents
  • Utilised and installed as combination linear heat detector and unit activation device to cause actuation of Fire Suppression Systems.

AutoFireX® MAX LINEAR PNEUMATIC AUTOMATIC FIRE SUPPRESSION UNITS UTILISING LISTED FIRE SUPPRESSION AGENTS

AutoFireX® Max Automatic Fire Suppression Units

Specially designed for Automatic Fire Detection & Suppression for small Enclosures.

This Linear Pneumatic Heat Detection tube when installed in a small enclosure, filled with fire suppressing agent and pressurised with Nitrogen, will detect heat/fire in the range of 85°C to 135°C . On impingement with this heat/fire, the tube ruptures at the hottest point, forming a dispensing Nozzle, from which the pressurised agent is discharged instantly directly on the source of the heat/fire extinguishing it instantly and flooding the area with the agent, thereby mitigating any spread or reignition of fire.

By utilising a pressure switch attached to the tube via an EOL on one end and interfacing with any existing FACP or Audio-Visual Alarm unit the activation of the unit can be annunciated, or functions like tripping the power supply or switching on/off ventilation etc. can be also achieved.

This automatic Fire detection & suppression is a standalone reliable and simple system that doesn’t require other hard wares or power input to activate and requires no maintenance. The system pressure can be monitored by visual check of the provided pressure gauge.
