Compact Automatic Fire Suppression System For Server Racks And Electrical

Product Specification

Cabinet heptafluoropropane gas fire extinguishing device

Product Introduction:
  The HFC-227ea (HFC-227ea/FM200) cabinet fire extinguishing system is an innovative automatic fire extinguishing product independently developed by our company. It is specifically designed for cabinets. Also known as a temperature detection and fire extinguishing all-in-one unit or prefabricated fire extinguishing system, this system pre-assembles the extinguishing agent storage device, delivery piping, nozzle, housing, pressure indicator, fire detector, and signal feedback device into a self-contained fire extinguishing unit. This system is suitable for various stand-alone cabinets, and one unit can protect one or more cabinets.

  The extinguishing agent used in this system is HFC-227ea (HFC-227ea/FM200), a clean gas fire extinguishing agent with both chemical and physical extinguishing properties. It is colorless, odorless, low-toxic, non-conductive, and non-contaminating. It does not damage property or delicate equipment. It can reliably extinguish Class B and C fires, as well as electrical fires, at a low extinguishing concentration. This device features two types of fire detectors: a temperature-sensitive glass bulb and a fire detection tube. This eliminates the need for a traditional fire detection system consisting of smoke, temperature, and fire controllers. Our products offer enhanced detection and extinguishing capabilities, are more adaptable to cabinet installation, save space, and do not impact cabinet components.


Device Application Locations:
1. Inside server cabinets for IT and computer systems;
2. Inside server cabinets for telecommunications and communication systems;
3. Inside control cabinets for banking equipment;
4. Various control cabinets for machinery and other industries


Working Principle:
  The cabinet HFC-227ea gas fire extinguishing system features two temperature-sensing activation methods: a thermo-sensitive glass bulb and a fire detector tube. When the ambient temperature in the protected area reaches the set burst temperature of the thermo-sensitive glass bulb (68°C, optional upon request), the bulb bursts, instantly opening the fire extinguishing medium release pipe. The gas fire extinguishing agent stored in the device is immediately ejected from the nozzle, cooling the protected area and extinguishing the fire. Another activation method uses the fire detector tube as a fire detector. When the fire detector tube senses a fire source signal (160°C ± 10°C), the gas inside the fire detector tube expands rapidly, eventually bursting a nozzle at the highest temperature point in the pipe. This triggers the fire extinguishing agent storage device, which is then released through the fire detector tube and out of the bursting nozzle, achieving cooling and extinguishing the fire.
