Carbon Dioxide (CO2)
What is Carbon Dioxide (CO2)?
Carbon Dioxide (CO2) is a widely used clean agent fire suppression gas designed for total flooding and local application fire protection systems. CO2 is a colorless, odorless, electrically non-conductive gas that leaves no residue after discharge, making it suitable for protecting equipment and machinery without causing secondary damage.
CO2 is stored in cylinders as liquid under pressure or in high pressure gaseous form depending on the system design. During a fire event, the gas is discharged rapidly into the protected area for fast fire suppression.
Carbon Dioxide extinguishes fire by reducing the oxygen concentration in the protected space to a level where combustion cannot be sustained making it highly effective on Class B and Class C fires, particularly in industrial and machinery-based hazards.
Refilling and Hydrotesting of Carbon Dioxide Gas Cylinders
Refilling and hydrotesting of CO2 gas cylinders at upto 300 bar requires a high level of expertise. Proper handling of these cylinders is important to ensure the reliability, safety and performance of fire suppression system.
Hydrostatic Pressure Testing of CO2 cylinders at such high pressure is a critical process and is done to check the strength and pressure holding capacity or elasticity of the cylinder walls. The test ensures that the cylinder can safely withstand operating pressures during system discharge.
Refilling Process
- Visual inspection of cylinders for internal and external physical damage, corrosion, dents or valve defects.
- Safe releasing of remaining gas from the cylinder.
- Evacuation of air, moisture or contaminants from cylinders.
- Refilling of CO2 cylinders using high pressure filling systems.
- Leak testing of the cylinders.
- Labeling of cylinders with refilling details and next inspection date.
Hydrotesting Process
- Complete depressurization of cylinders and removal of valve.
- Filling of cylinder with water.
- Pressurization of cylinder with water at its test pressure.
- Rejection of cylinder showing signs of permanent expansion, leakage or structural weakness.
- Drying of cylinders and refitting of valve.
- Test date stamping and certifications.
