HFC-227ea gas extinguishing system is referred to as gas extinguishing, also called as extinguishing system with pipe network,also called as ***00.HFC-227ea fire extinguishing agent is colorless, tasteless and non-conducting, and it does not pollute protected object. This product is especially without destructive effect for atmospheric ozone layer (ODP value is zero), and meeting environmental requirement. It is an relatively ideal alternative of haloalkane fire extinguishing agent recognized by our country and ISO as well as developed countries, having the characteristics of cleanness, low toxicity, good electrical insulation property, high extinguishing efficiency, fast speed and no secondary pollution, as well as the function of explosion suppression.
The HFC-227ea gas extinguishing system developed by Leader Haixin is designed, manufactured and tested according to the latest standard (GB25972-2010) and specification (GB 50370-2005), with complete and precise design parameter as well as complete function. Its operation is reliable and safe, and sealing property is good. Major innovation tests are conducted for some parts, such as cylinder valve of fire extinguishing agent. The sealing outlet of cylinder valve not only adopts structural design of double seal and vibration and deformation prevention, but also changes filling technology, which make double assurance for sealing performance and fill in the inland blank. HFC-227ea gas extinguishing system is referred to as gas extinguishing, also called as extinguishing system with pipe network,also called as ***00.Protective cap is installed for each fire extinguishing agent cylinder of the system to ensure personal safety of operator during processes of product transport, loading and unloading, installing and debugging.
HFC-227ea gas extinguishing system is referred to as gas extinguishing, also called as extinguishing system with pipe network,also called as ***00.Characteristics of HFC-227ea gas extinguishing system with pipe network: (1) An extinguishing system with pipe network can protect eight protective zones at the same time, and total engineering cost of the project will lower; (2) convenient for centralized monitoring and maintaining; (3) The device needs cylinder assembly room; (4) only suitable for new project; (5) design calculation and program are complex; (6) Installation is complicated and construction period is long.
Application scope: HFC-227ea gas extinguishing system is referred to as gas extinguishing, also called as extinguishing system with pipe network,also called as ***00: 1. Fire disaster of electrical and electronic equipment; 2 Fire disaster of flammable liquid and meltable solid; 3 Fire disaster of solid surface; 4 Fire disaster of gas that air supply can be cut off before fire extinguishing.
HFC-227ea gas extinguishing system is referred to as gas extinguishing, also called as extinguishing system with pipe network,also called as ***00.It is widely used in the following closed space: 1. Places, such as computer room extinguishment, communication room extinguishment, museum extinguishment, archives extinguishment, library extinguishment, power distribution room extinguishment, mobile machine room extinguishment, telecom center extinguishment, offshore oil platform extinguishment and so on; 2. Facilities that may be damaged by water with the usage of water spray system; 3. Equipments and zones difficult to remove residue after blowout of fire extinguishing chemicals, such as dry powder, aerosol and water; 4 Regions always having people working, such as computer room and communication control center.
