Automatic CO2 Extinguisher Filling Machine

The machine is specially designed for refilling CO2 and Nitrogen into fire extinguisher.

The machine adopts compressed-air as power source, through the air-driven gas booster pump to CO2 into fire extinguisher. 

When filling weight reaches your preset weight value, the machine will stop filling automatically, meanwhile, the machine will remind the operator with flashing alarm.

Working Circuit

Features

• Powered by 3-8 bar compressed-air

• Safely used in explosive-proof areas

• 4 in 1 of Fire bottle vacuuming + CO2 filling + N2 filling + Weighing

• Automatic filling & full stop

• Max filling pressure 128 Bar (higher filling pressure is customizable)

• Filling pressure can be regulated

• Filling weight can be preset

• Equipped with nitrogen pressure reducing valve and precision pressure gauge to accurately monitor nitrogen filling pressure 

Technical Parameters

• Filling pump power source: 3-8 bar compressed air 

• Vacuuming pump power supply: 220V 

• Medium: CO2/ Nitrogen

• Vacuuming pressure: -0.08MPa

• Maximum gas filling pressure: 12.8MPa 

• Filling rate: 8-10kg/minute

• Pressure accuracy: ± 0.1MPA

• Weighing range: 0-500kg

Operating Procedure

(1). Vacuum fire bottle: Extract residual reagent out of the fire bottle, vacuum the fire bottle to -0.07MPa.

(2). Fill new reagent into fire bottle: Preset a filling weight on electronic scale, then fill CO2. When the preset filling weight is reached, stop filling automatically, meanwhile, flash alarm activate.

(3). Fill Nitrogen into fire bottle
