What is the minimum diameter for the condensate line of a 20-ton package unit?

The minimum diameter for the condensate line of a 20-ton package unit is determined by the volume of condensate produced and the need to ensure proper drainage without backups. A 1-inch diameter is typically adequate for a unit of this size, as it allows for sufficient flow while preventing any potential clogs from forming.

Choosing a diameter that is too small would risk an increase in pressure and can lead to inefficiencies or buildup, while selecting one that is excessively large may not be necessary for the volume of condensate produced in this specific context. This standardization ensures compliance with plumbing codes and optimizes the system's performance.
