Automatic Fire Suppression Systems
Tube-based extinguishers are compact and can be installed directly within machinery or equipment, allowing for immediate response to fire. Tube-based systems can come in various forms. One of which is a direct system where in the presence of heat the tube breaks where the fire is located. This releases the extinguishant directly onto the fire. An indirect system uses a tube to detect a fire but requires additional fitting of a steel conduit which releases the extinguishant. This form of tube-based fire suppression is great for suppressing a fire in a large area. A direct system isn’t as complicated to install however it only covers the area directly under the release of the extinguishant.
How Automatic Extinguishers Work?
Automatic fire extinguishers are engineered to respond to fire threats swiftly and efficiently. These devices work by detecting temperature fluctuations that indicate the presence of fire. Typically, they are equipped with a heat-sensitive bulb, known as a Quartzoid Bulb Detector (QBD). If in the presence of extreme heat, the QBD breaks and the extinguishing agent is released. These heat-sensitive bulbs are available at various temperature thresholds, allowing for customisation based on the specific requirements of the environment and potential fire hazards.
Upon activation, the extinguisher releases a suppression agent such as dry powder, foam, or gas, depending on the type of fire hazard identified. The agent rapidly fills the area, smothering the flames and reducing the oxygen level to prevent re-ignition. This automatic process is crucial in environments like server rooms and other unmanned areas where human intervention might not be immediate. By operating independently, automatic extinguishers mitigate potential damage and ensure that fires are controlled before escalating, safeguarding equipment and minimising operational downtime.

Tube-Based Automatic Fire Suppression Systems

Ceiling-Mounted/Wall-Mounted Fire Suppression Systems
Ceiling-mounted automatic fire extinguishers provide widespread coverage in large areas, making them ideal for open spaces and facilities where floor access is limited. Wall-mounted extinguishers are positioned along walls for easy accessibility and are suitable for corridors and exit routes. Wall-mounted extinguishers are suitable for where a ceiling-mounted automated extinguisher wouldn’t be applicable, such as on a drop ceiling or an extremely tall ceiling.
Rack-Mounted Fire Suppression Systems
Rack mount fire suppression units are ideal for server racks where there is a need to provide a fast and responsive solution to protect mission critical IT devices. The use of a smaller amount of fire extinguishant can be more effective and less costly than a complete room flood, allowing operations to continue and minimising or completely removing downtime.
• Localized Protection:
Protects high-risk areas in the rack, reducing downtime and damage in unaffected spaces, and offering targeted fire suppression exactly where needed without disturbing other areas.
• Quick and Efficient Suppression:
Rapid fire detection and suppression contain fires within seconds, minimizing damage to equipment, data loss, and service interruptions.
• Easy Installation and Integration:
Compact design fits standard racks, requiring minimal setup and integrates smoothly with fire alarm systems, enhancing safety with simple installation.
Micro-Extinguishers for Micro-Environments
Automatic fire extinguishers are traditionally available in larger sizes, often from 2kg up to around 15kg, however as technology has advanced, smaller options are now available in formats as small as 200g. These compact fire extinguishers are ideal for small, sensitive environments like electrical cabinets, server racks, and control panels. They can be installed in various settings including residential properties, educational facilities, industrial spaces, and healthcare facilities, protecting critical infrastructure and equipment from fire risks. They can either be inserted within a fire risk, such as a power supply unit, or installed externally with a tube that feeds into the unit.
