Guideline N Updates Remove Paint Color Assignments for Refrigerant Containers

Significant changes to refrigerant container color protocol will commence in January 2020, as outlined in the Air-Conditioning, Heating, and Refrigeration Institute’s (AHRI) Guideline N, Assignment of Refrigerant Container Colors. Guideline revisions, first published in 2015, specify that all refrigerant containers should have the same paint color, RAL 7044, to reduce confusion among similarly colored refrigerant containers.
