How many different refrigerants can be recovered in the same tank?

The number of different refrigerants that can be recovered in the same tank depends on the tank's design and regulatory guidelines. Typically, it is not recommended to mix different refrigerants due to potential chemical reactions and contamination issues. Most regulations require that refrigerants be recovered separately to ensure safe handling and environmental compliance. Therefore, it is best practice to use separate tanks for different types of refrigerants.
