If a refrigerant cylinder is identified as orchid, which refrigerant does it contain?

The refrigerant cylinder identified as orchid contains R-502. The identification color coding for refrigerants is a system designed to quickly convey important information about the contents of the cylinder. In this system, R-502 is specifically designated as the color orchid.

R-502 was widely used in refrigeration applications, particularly in commercial refrigeration and in certain air conditioning systems. Understanding the color coding is crucial for safety and regulatory compliance, as it helps technicians quickly identify the type of refrigerant they are working with, ensuring proper handling and reducing the risk of accidents.

The other refrigerants mentioned—R-11, R-22, and R-134a—have their own distinguishing colors; for example, R-22 is typically associated with a green color. Therefore, recognizing the color associated with R-502 as orchid confirms its identity, making it easier for technicians to manage refrigerants safely and efficiently.
