Why are refrigerant cylinders color coded?
Refrigerant color codes are useful for us to recognize the type of gas that is stored in the cylinders. The name of the gas are usually labelled on the cylinders as an added aid so that we will not make any mistakes in recognizing them. Putting the wrong gas into our air conditioning systems can damage the compressors.
What color are refrigerant tank?
The number of colours for refrigerant cylinders will be reduced from today’s rainbow of colours to just one – an off-white or “dirty” white. Cylinders containing flammable refrigerants will continue to have a red band.
What color is R-410A refrigerant?
R-410A cylinders were colored rose but are no longer specially color-coded, now bearing a standard light gray color.
What color is R-22 freon?
light green
Originally, Guideline N stipulated different paint colors for refrigerant cylinders for quick and easy recognition, such as light green for R-22, orange for R-404A, light blue (sky) for R-134a, and rose for R-410A.
Why are refrigerant tanks GREY?
If your favorite color is neutral gray-green, you’re in luck, because refrigerant cylinders are destined to lose their current kaleidoscope of colors and take on one consistent shade of gray.
Which refrigerant is green?
R290 is pure and eco-friendly, and has been named as the preferred green gas refrigeration option by the Environmental Protection Agency (EPA) due to its high efficiency and energy savings alongside its environmentally friendly impact. All these natural, green gases have among the lowest Global Warning Potential (GWP).

What is R32 and R410A?
R410A is a refrigerant mixture of R32 and R125 with 50/50 wt. %, and R32 is a pure fluid. The molecular weight of R32 is 28% lower than that of R410A. Critical pressure and temperature of R32 are 850 kPa and 6.0 K respectively higher than those of R410A. Both R410A and R32 have very similar boiling point.
Is there a color guideline for refrigerant color?
There is a published refrigerant color guideline from the Air-Conditioning , Heating, and Refrigeration Institute out of Virginia. This guide line is from 2012 but it is still relevant and useful today.
How do you identify a refrigerant?
Refrigerants are identified by number. Number followed by a letter ” R”, which means refrigerant. This definition system has been standardized by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE).
What does R mean in refrigerant numbers?
Number followed by a letter ” R”, which means refrigerant. This definition system has been standardized by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). Refer to Chapter 31 summary ASHRAE numbering system. You should familiarize yourself with the refrigerant numbers and names.
Why are refrigerant cylinders color-coded?
Refrigerant cylinders are color-coded to allow easy identification of the substances they contain. This practice helps prevent accidental mixing of refrigerant in the system. Carefully read the label and identification before using refrigerant cylinder.
