What is the maximum percentage of refrigerant that can be stored in a cylinder?

The maximum percentage of refrigerant that can be stored in a cylinder is typically around 75%. This limit is in place to ensure safe storage and handling of refrigerants. Storing refrigerant cylinders at this level allows for proper venting of vapor and prevents issues such as excessive pressure buildup, which can occur if the cylinder is overfilled.

Cylinders are designed with a specific capacity in mind, and maintaining the refrigerant level at or below 75% helps accommodate the expansion of the refrigerant vapor. If containers were filled to a higher percentage, particularly near 100%, it could lead to safety hazards, including rupturing of the cylinder due to pressure increases, especially with temperature fluctuations.

Understanding these limits is crucial for professionals working with refrigerants to ensure safety and compliance with handling regulations. Thus, the choice of 75% aligns with industry standards and safe practices.
