Frogen R600A
General Information
Isobutane, or R-600a, is a hydrocarbon that is used in some refrigeration equipment, such as domestic fridges or small commercial refrigerated appliances. The volumetric capacity of R-600a is approximately 50% less than that of R-12 and R-134a, so it cannot be used as a replacement for them.
When working with hydrocarbon refrigerants, it is very important that they are very pure, as if there are any impurities present (Sulphur, water, etc.) it could cause the oil lubricants in the system to degrade and damage the compressors, among other things. Furthermore, if the hydrocarbon is not very pure it can sometimes be mixed with other hydrocarbons, which can drastically alter the physical and thermodynamic properties of the original hydrocarbon.
The isobutane that is used in refrigeration applications is not odorized, as it is when used for domestic purposes (domestic hydrocarbons are odorized so they a leak can be detected quickly). It is therefore not easily detectable when there is a leak.
As is the case with (Frogen R600A) or all other kinds of hydrocarbon refrigerants, isobutane is generally highly miscible with all types of lubricants. As mineral oils and these refrigerants are highly soluble together, it may be necessary with some systems to use more viscous oils to compensate for this increased solubility.
Lubricants that contain silicone or silicates are not recommended. We would recommend that you follow the instructions in any case, or that you use the lubricants recommended by the compressor manufacturer.
