Description

Evaluating the best choices for fire protection always requires a careful examination of risk factors that can vary from one use case to another—and even from one site to another. Water sprinklers and misting systems have their place in many scenarios. The same is true of manmade chemical agents. But for certain highly-sensitive environments, textile and electronics, inert gas fire suppression can be the ideal choice. To understand why, it's important to start with a simple question: What exactly is inert gas, anyway? Think of it this way. The normal air in our environment is about 20.9% oxygen, while the remaining air is made up of inert gasses, including nitrogen (78%) and traces of argon, carbon dioxide, neon and helium. These inert gasses are non-reactive to chemical interactions, making them ideal for fire suppression. Like water, inert gas is 100% natural. But instead of soaking fire, it suffocates it, without endangering people who may still be nearby as discharge begins. Here's how. Harness nature itself to fight fires in a way that’s fast, effective, safer for humans and completely neutral to the environment. FIGHTING FIRE THE NATURAL WAY Fighting Fire the Natural Way In most cases, an inert gas or “clean fire suppression agent” is comprised of 100% nitrogen, 100% argon, or a combination of the two. Automatic, “total flooding” systems apply the agent in sufficient concentrations to smother a fire by displacing the oxygen in the protected zone to a level below which fire cannot burn, but is still safe for humans who may still be evacuating. are no chemicals, no toxic by-products, and no residues, so there’s nothing to clean up. Offices,Hospitals and Human-Occupied Areas. In environments that include server rooms, electronics and a high incidence of paper and other flammable materials, inert gas fire suppression is a natural choice. Fires are gently smothered without chemicals or liquid coming into contact with vital documents or equipment. They can also help public institutions meet environment-friendly best practical. HoW IT FUNCTION The inert gas suppressing device consist of vital components to ensure efficiency in fire detention and suppression. 1. Air sampling smoke detector system: Continuously analyses the room air actively by taking air samples and detects even minimal smoke production as early as possible 2. Pressure relief: Prevents an impermissible rise in pressure when the extinguishing zone is being flooded 3. Smoke detectors: Monitor the extinguishing zone and send an alarm to the extinguishing control panel if smoke is detected 4. Gas extinguishing nozzles: Distribute extinguishing gas uniformly throughout the entire extinguishing area 5. Acoustic and optical alarm devices: Ensure that everyone is able to evacuate the protected area during the preliminary warning period 6. Manual release Makes it possible to activate the extinguishing system manually if a fire is discovered 7. Fire detection / extinguishing control panel: Processes fire detection signals, triggers alarm and floods the extinguishing zone after the specified preliminary warning period 8. Extinguishing cylinders: Hold 80 or 140 litres of non-liquefied extinguishing gas under 300 bar pressure, supplied individually or in space-saving cylinder batteries. AFFORDABILITY There is no maintenance cost of the device when installed, the only little cost should be the refilling of gas after use.
