A CO₂ filling station is a system or facility designed for filling carbon dioxide (CO₂) gas into various containers, such as cylinders, tanks, or cartridges. These filling stations are used in a variety of industries and applications where CO₂ is needed in gaseous or liquid form. Below are some common uses and applications of CO₂ filling stations: Key Uses of CO₂ Filling Stations: Industrial Gas Supply: Welding and Cutting: CO₂ filling stations are essential in the metalworking industry, where CO₂ is used as a shielding gas in welding processes like MIG (Metal Inert Gas) welding. It helps protect the weld area from oxidation and contamination. Fire Suppression: CO₂ is used in fire extinguishers, particularly for electrical fires. Filling stations are used to recharge or fill CO₂ fire extinguishers.
