Introduction to the Control Methods of Heptafluoropropane Fire Extinguishing Systems
What are the different control modes available for heptafluoropropane fire suppression systems? Many people may not be very familiar with them, so let me give you a detailed introduction. Industry insiders say there are typically three control functions: automatic control, manual control, and mechanical emergency activation.
1. Automatic control means that the automatic control mode on the fire extinguisher can be set to the “Automatic” position. Once a fire breaks out in the protected area, its signal will be transmitted to the controller, at which point an alarm sound will immediately be triggered.
2. Manual control means setting the control switch to the “Manual” position. Once a fire occurs in the protected area, the detectors will sense fire-related information. At this point, the controller will emit audible and visual alarm signals. However, at this stage, the on-duty personnel must first confirm the fire before pressing the emergency start button. Only then will the heptafluoropropane extinguishing agent be released to put out the fire.
3. Another method for initiating the heptafluoropropane system is mechanical emergency activation. Once a fire breaks out in the protected area and the control system fails to start due to a malfunction, the on-duty personnel must first confirm the fire alarm before activating the emergency response. Simply pressing down the manual button with a vehicle will trigger the fire suppression system.
In what types of venues is heptafluoropropane generally used?
In China, it is frequently used in various critical environments such as power, water conservancy, metallurgy, banking, and civil aviation systems. It can also be applied to hazardous areas—such as computer rooms and telecommunications equipment rooms—that contain numerous flammable and combustible electrical devices and are prone to fires.
Heptafluoropropane is a fire-extinguishing agent that can be stored in liquid form. It exerts both physical and chemical effects. Its chemical effect lies in its ability to inertate active free radicals in the flame, thereby interrupting the chain reaction and extinguishing the fire. As for its physical effect, during the vaporization stage of the molecules, it rapidly cools the flame temperature, which in turn reduces the concentration of oxygen in the combustion zone, ultimately leading to fire suppression.
Our company has long been at the forefront of technological development in the field of fixed fire-extinguishing equipment products. Currently, our main product lines include: cabinet-type heptafluoropropane gas fire suppression systems and heptafluoropropane fire suppression equipment (4.2 MPa/5.6 MPa), IG541 gas fire suppression systems, dry powder fire extinguishing systems, foam fire suppressants, automatic fire suppression systems with detection tubes, kitchen equipment fire suppression systems, and several other major categories, all available in a wide range of specifications and models. We also offer a comprehensive selection of piping and fittings, as well as pressure relief devices, to complement various gas fire suppression systems. In addition, we provide fire protection design services, fire maintenance and upkeep, and other technical services centered around gas fire suppression equipment.
