I must say R407c is not a very good gas, where loosing 10% can cause the systems pressures to surge and the gas becomes separated chemically. There are some new gasses out there that are molecularly bound and can be vapour charged! but which one is the best for R-22 (drop in replacement)?
i have a ton of of the stuff to suck and replace!
For R22 existing systems solution to an direct replacement is using HFC R 427A(FX 100).
Try this link.

Why would anyone want to replace R22? Recycled R22 will be available as long as 2015, so no hurry, and especially don't use R422 and R417, which already proved to be junk refrigerants.

Not necessarily. Retrofitting will cause R22 to be gathered and recycled (which is law requirement). And there are too many plants around with R22 in them.Quote:

But if you are convinced, why don't you buy some tons of R22 and sell it next year?
Because stockpiling is illegal?Quote:

Correct me if im wrong, but i dont think you are forced to remove the gas from a working unit. only when its lost it charge that you can't put R22 back in?
or have i had been told a porky?
That is correct WOMBATQuote:

From 01-01-2015 all R22 units that are found to be leaking, must have refrigerant removed and sent for disposal and the unit must be retrofitted or replaced.:cool:
Should mean plenty of work for us fridgies over the next few years :D
and all EU countries are working to the same EU Rules :)
Just checked this also applies to all HCFC's and HCFC blends
So, no touch R22 units. The only good reason for that is to correct and remove leakages.
Thanks for the details

Of course it will.Quote:

With no leaks of course. This is not meant to be funny or disrespectful just thought provoking. After all we can use recycled 22 untill 2014. And we a going to be ripped of big time by the refrigerant manufacturers in the meantime!:mad:Quote:

If u have to choose between R-422 and R-407 for replacing r-22??
R 422 more perspective?.
YOu can reuse recycled/regenerated r-22 until end of 2014.
You can recover and recycle on site with a Spanish system. So there is no need to buy regenerated one at the price it is now(crazy), as you can have it for free from the existing installations.
Check here interesting info about retrofits and leakages control, regarding European Regulations 1005/2009 and 842/2006 respectively.

Hope it will help you.
