R508A Refrigerant Gas,R508B is an azeotropic blend of non-ozone depleting HFC refrigerants (R23 and R116).  It has similar properties to R503 and is used for very low temperature applications, such as environmental test chambers and medical freezers.

Although R508B is an azeotrope, we recommend it should always be removed from the cylinder as a liquid when charging the system.  R508B is not compatible with mineral oil, and equipment manufacturers recommend Polyol Ester (POE) oil – see our Lubricants section.

R508B can also be used to retrofit existing systems containing R503, however it will be necessary to change the oil to POE.Buy R508A Refrigerant Gas

It has a GWP greater than 2500 and virgin product cannot be used for servicing in the UK and EU in stationary refrigeration applications > 40 CO2 T eq. There is an exemption for systems operating below -50 degrees C.

R508A is suitable as a high pressure refrigerant for applications in the low temperature sector. Cooling temperature of R-508A can be reduced to -80 degrees Celsius or even lower

R-508A is intended for very-low-temperature refrigeration systems, typically the low stage of a multi-stage system. R-508B has properties similar to R-503 and can be used to replace either R-13 or R503 in an existing system.

Use R508A or B depends on the degrees of cooling temperature you needs, we can customize the blending ratio according to your working conditions

R508B is an HFC/PFC (Perfluorocarbon) blend designed to be a replacement for R503 or R13 in very low-temperature refrigeration systems, such as environmental chambers and biomedical freezers.

R508A Refrigerant Gas Replaces.
R-13, R-23, and R-503

Very low temperature [below -40°F to -150°F (-40°C to -101°C)]:
medical freezers
environmental chambers

Endorsed by many OEMs.
Longer equipment life: Lower discharge temperature than R-23, increases compressor service life.
Increased cooling capacity: 30% greater cooling capacity than R-13.
Best match for R-503.
Lower retrofit cost than R-23.
