- Mixture consisting of 52 % HFC-143a, 44 % HFC-125 and 4 % HFC-134a.
- Mixture consisting of 53 % HCFC-22, 13 % HFC-152a and 34 % HCFC-124.
- Mixture consisting of 38 % HCFC-22, 60 % HFC-125 and 2 % propane.
- Mixture consisting of 25 % HFC-125, 52 % HFC-134a, and 23 % HFC-32. (5) Mixture consisting of 46 % HFC-143a and 7 % HFC-125.
- A HCFC mixture consisting entirely of HCFCs, where the GWP - in accordance with the climate convention guidelines - is 0, since the mixture does not contain greenhouse gases. The real GWP value is 1,440.
- Mixture consisting of 50 % HFC-32 and 50 % HFC-125
- Mixture consisting of 50 % HFC-125, 50 % HFC-143a.
