What is important to clarify, after what we’ve addressed in the previous article, is that every gas, if recycled, can not end up in equipment similar to those from which it was extracted. Severe thing: The EN378 norm is definitely not very precise in this area, so there are mostly technical reasons as well as legal reasons that impose these limits. It is also necessary to reflect on the fact that, if on one hand (in theory) a Freon can be recycled and reused in ever new machines, on the other hand, as we have seen, these machines can never be really new if you want to recycle the gas... In addition, the last few years have seen an exponential development of Freon use. To make a comparison, what’s the point of replacing a car with a minimally revised and correct version of it, only to continue using the same fuel, when there are more advanced cars on the market and less polluting fuels? None.

It should be remembered, however, that each portion of gas reused will be a gas that must not be disposed. However, the modern disposal process is likely to have evolved enough to reduce the motivations on why to recycle and not to dispose, mainly for cost reasons, more than for environment reasons. Therefore, what we want to emphasize, is the myopia with which this Freon regeneration is often considered.

Finally, regardless of the reason for which you choose to recover a used gas, it should be considered that this must first be filtered and distilled to be brought back in new conditions. Then... who decides when a gas is still adequate? In this case two tests are prescribed according to the same EN378 norm: acid test and moisture test, which we will address next week.
