JIANGXI ZHIYUAN FIRE TECHNOLOGY CO.,LTD

The hanging hot aerosol fire extinguishing device is a new type of environmental protection fire protection product with the world's advanced level. It is a new type of high-tech green fire protection product further developed on the basis of the third generation of S-type aerosol.
1、 Product Features:
(1) Green environmental protection products: good cleanliness, atmospheric ozone layer destruction capacity index = 0, global greenhouse effect capacity index = 0.
(2) Stainless steel alloy cylinders will not be corroded, no pressure relief, no leakage, low maintenance.
(3) Passed the fire extinguishing test and certification of the Sky Consumption Institute.
(4) Fire extinguishing without residue: The fire extinguishing agent below 2um is released and is easily dissipated in the air. The amount of particles is less than the amount of dust that naturally falls in a closed computer room within a month.
(5) Lightweight: The volume and weight of other fire extinguishing systems can be reduced by 90%, and it does not occupy the protective area.
(6) Easy to install: no high-pressure vessel or complex distribution network is required, saving space and expensive installation costs.
(7) Convenient design, wide range of adaptation.
(8) The service life is up to 10 years, which is better than other types of fire extinguishing agents.
