General Fire and Safety provides CO2 recharging for commercial cylinders across various industries. CO2 extinguishers and cylinders are filled with non-flammable carbon dioxide gas under extreme pressure. CO2 cylinders range in size from 5lbs to 100lbs, or even larger. Refilling a CO2 extinguisher or cylinder requires gas-compressing equipment from our facility and the expertise of our staff. All CO2 extinguishers undergo hydrostatic testing and recharge every five years. General Fire and Safety offers professional and expert refilling, recharging, and hydrostatic testing for optimum performance of CO2 extinguishers and cylinders.
