Why do you need color coding on refrigerant cylinders?
The color coding prevents accidental mixing of refrigerants, improper application, and helps to inform the technician on how to handle the refrigerant. Having colored cylinders will not only save you time but it can help to ensure that you are using the proper refrigerant.
