GTM-D carbon dioxide fire extinguisher filling machine
The model GTM-D carbon dioxide fire extinguisher filling machine is a special-purpose equipment for filling the carbon dioxide fire extinguishing agent automatically into model MT2-MT7 etc. portable type fire extinguisher. This machine adopts low temperature freeze technique to convert the high pressure carbon dioxide fire extinguishing agent in the gas storing cylinder into low- temperature low-pressure pure liquid state carbon dioxide through the low temperature conversion device in the machine and fill it into the low-temperature fire extinguisher. It does not need heating, pressuring, and has safe, reliable, rapid filling speed, accurate metering, high work efficiency etc advantages. It is an ideal filling equipment for carbon dioxide fire extinguisher production and maintenance factories.
