In NH3 systems, what is a common application for the maximum quantity of 500 pounds?

In NH3 (ammonia) systems, the common application for the maximum quantity of 500 pounds typically refers to institutional use. Institutions often include larger facilities such as schools, hospitals, and correctional facilities, where ammonia may be used for refrigeration or other purposes.

These institutions are likely to have the infrastructure and safety measures in place to handle ammonia safely, as well as the trained personnel required to manage it effectively. The maximum threshold of 500 pounds is relevant in this context, as it indicates the capacity for consistent and safe usage under regulations that govern the handling of ammonia in such settings.

In contrast, commercial and residential applications usually involve lower capacities due to the scale of operation and safety regulations that apply to smaller or more common use cases. Public assembly spaces may also have different considerations regarding occupancy and safety that influence the amount of ammonia that could be stored or used, making institutional environments more fitting for this quantity.
