What percentage weight loss triggers a recharge for high-pressure CO2 cylinders?

• A. 5%
• B. 15%
• C. 10%
• D. 20%

Answer: (C)

For high‑pressure CO2 cylinders, the trigger for recharging is based on weight loss. You compare the current weight to the full (charged) weight, and when the cylinder has lost about 10% of its full weight, it should be recharged. This fixed percentage provides a consistent, size‑independent rule so the cylinder has enough CO2 at the required pressure for reliable operation. Smaller losses (around 5%) can occur from handling or minor leaks and aren’t a solid signal to recharge, while larger losses (15% or 20%) mean you’re running well below the needed content and risk insufficient performance. If you see a significant weight drop, it’s also a good prompt to check for leaks and fix any issues before recharging.
