Hello Fridgies,
On another thread you guys worked out what refrigerant I need for the low temp side of a -86 degree dual cascade freezer-- R23 plus a bit of 290 to aid oil return.
I live and work in Laos so nothing is avaliable here.
We still use R22 and R12 shipped in from China who manufactures there.
Bangkok has quoted me 84 000 Baht / $2360 USD for 8KG Bottle of R23.
Nearly more than the freezer is worth!!
Do I have any alternatives and what is the realistic price of R23? I am also searching China for old stock of R13 and R503 or Suva 95.

As always your help is appreciated and you will be able to claim free beer when you visit Laos !!! as well as a bed and food.
Best Regards
