What is the maximum amount of refrigerant you can put in a 250 lb. cylinder?

In the context of refrigerant cylinders, each cylinder has a specific maximum fill capacity referred to as the "net weight" of refrigerant that it can safely contain. For a 250 lb. cylinder, the maximum amount of refrigerant that can be filled is typically regulated to allow for safety and proper operation.

The choice of 200 lbs as the answer indicates that the maximum recommended fill is often set at 80% of the cylinder's stated capacity. This allowance prevents overfilling, which can lead to increased pressure and potential safety hazards. Excess refrigerant can also prevent the cylinder from functioning efficiently or lead to leaks.

The other options suggest higher capacities than are considered safe under normal circumstances for such a cylinder. By adhering to the guideline of a maximum of 200 lbs for a 250 lb. cylinder, you ensure compliance with safety standards and best practices in refrigeration handling. This understanding is crucial for anyone involved in the refrigeration industry to maintain safe practices and to avoid accidents related to improper filling of refrigerant cylinders.
