Guangzhou Rong 'an Fire Equipment Co., Ltd. is a professional fire equipment manufacturer integrating research and development, design, production, sales, installation and service
Our cabinet HFC-227ea fire-extinguishing device has passed the national compulsory product certification and the National Fixed fire-extinguishing system inspection Center, and obtained the 3C certificate and the external pressure storage HFC-227ea fire-extinguishing system technical appraisal certificate. The factory has passed the ISO9001 quality system certification, and is fully insured by Ping An Insurance of China.
Working principle of external storage pressure HFC-227ea fire extinguishing system:
When the fire detector detects the fire, the fire signal will be fed back to the alarm control device, which controls the sound and light alarm, sends out the evacuation alarm signal and controls the linkage device. After 30S delay, the alarm control device outputs the starting electrical signal (DC24V,1.5A) electromagnetic drive action to the electromagnetic drive of the cabinet HFC-227EA fire extinguishing device. The fire extinguishing agent group is opened to release HFC-227ea fire extinguishing agent, which is sprayed into the protected area through the nozzle to achieve the purpose of fire extinguishing. When the high-pressure fire extinguishing agent flows through the pipeline, the micro switch in the signal feedback device is closed, and the signal feedback action feedback electrical signal is sent to the alarm control device to indicate that HFC-227ea fire extinguishing agent has been discharged.
Scope of application: cabinet HFC-227ea fire extinguishing device does not need to design special bottle group, the whole cabinet is designed in the protected area, suitable for computer room, archives, valuables storage, communication room and other small space protection area, several cabinet devices can be used together to protect the larger area.
