The other day I was trying to find a comprehensive listing of which cars were using the newer R-1234yf HFO refrigerant. Over in Europe YF refrigerant is now the standard for all new vehicles. (In some cases R-744 is used as well.) R-134a is no longer used due to its high Global Warming Potential. A... more»

Last month I wrote on the International Electrotechnical Commission (IEC) and their decision on rather or not to increase the allowed charge limit on hydrocarbon refrigerant applications.

Hello all, I apologize for the two e-mails in one day but I figured this one was worth it. Over the past week I have had a few notifications from my contacts within the industry about incoming price changes. First, before we get into what these changes are I want to take a look at why they are... more»

Last Friday the International Electrotechnical Commission (IEC) voted against increasing the charge limits on flammable hydrocarbon refrigerants such as propane (R-290) and isobutene (R-600a). The proposed changes aimed at increasing the global standard charge limit to five-hundred grams. Today,... more»

It is human nature. If the demand is high enough then the market will provide. It doesn’t matter if the product is illegal or not. If there are people willing to pay for it than others will provide the product, even if there is great risk involved.  When most people hear the terms ‘black... more»
