Last I heard 404a was considered a long term refrigerant.
Anyone hearing any scuttlebut on this? Any info would be generously accepted, thanks!

Of course they would get rid of it, it's a good widely used refrigerant. Only makes sense to get rid of it.
On a serious note, I had heard some rumblings about that but I have no solid info.

Did the patent run out ? Oh ya that was DuPont sorry.
I heard they are targeting it in Europe because it has a high GWP (global warming potential). I had the question posed by a produce warehouse customer who has an aging R22 skid that blew a 1 3/8 discharge vibrasorb this fall. Lost 1100 lbs of R22 and wasn't real happy. I am trying to sell him on R404A but he's afraid the same will happen as R22. I figure that about 6 months after I get him to install the R404A unit, the EPA will announce their terminate date. DuPont has a spy watching me.
Haha we'll have to start pulling trailers
R407F is the future!
I know people will tell ya it's 407A & 407C.
But 407F is the bees knees.
404 does have a phase out date can't remember when it is , but when I get to my office I will post it....
Isn't sanity just a one-trick pony anyway? I mean, all you get is that one trick, rational thinking, but when you're good and crazy, well, the sky's the limit!
Yes r407f starting to be put into medium temp racks here .R407A ,C & F all made up of the same 3 gases just different percentages (R32,R125,R134A)
Thanks for the link PL. I wonder how long they will keep it European? I sure hope they don't develop something different to run parallel here in the US, but I guess it all comes down to money and gov't pressure. Maybe they want the Brits to run the bugs out before intro here... Anyone using or have experience with 407F?
Thanks very much. I have a million more questions, but I'll do some research first.
