Specification XZFTBL6 XZFTBL8 Extinguisher classification 13A,14B 21A,18B Weight of extinguisher agent (kg) 6±0.03 8±0.04 Nitrogen pressure (Mpa20 ±5) 1.2±0.12 1.2±0.12 Effective spray time (s) ≤9 ≤10 Put out the fire time (s) ≤6 ≤8 Spary residual rate (%) ≤2 ≤2 Delayed-action time of discharge(s) ≤20 ≤20 Application temperature () -10 +50 -10 +50 Safeguard radius ≥0.94 ≥1.07 A temperature-sensitive glass ball is installed on the nozzle of the spray header of mounted stored pressure dry power fire-fighting equipment, and in normal conditions, the upper end of the glass ball bears against the sealing strip on the nozzle. When there’s a fire, the temperature goes up, liquid in the glass ball automatically breaks because of expansion by heat, the sealing strip automatically falls off and dry power agent in the fire-fighting equipment with nitrogen’s drive sprays from the nozzle to extinguish fire. This series of fire-fighting equipments can extinguish fire quickly and can be used safely, and toxicity of the extinguishing medium is low.
