Next refrigerant to replace 404a

[Helioson]

Anyone hearing any scuttlebut on this? Any info would be generously accepted, thanks!

Last I heard 404a was considered a long term refrigerant.

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.

Or admit how toxic it is to the ozone...where have we heard that before? Ha!

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.

I've heard the same thing about it being phased out due to high GWP ratings a few months ago by a local supplier

If they come up with one more refrigerant for stock on my truck !!!!!!!!!

[mjm88]

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.

[skpkey9]

404 does have a phase out date can't remember when it is , but when I get to my office I will post it....

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)

Profits must be down at the almighty Dupont

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?

Have you had any experience with this stuff?

It's here now, I've used it, it's in my van.

One of our chain customers requirements is we use R407F on R22 systems that have lost its charge.

Thanks very much. I have a million more questions, but I'll do some research first.

, POE only gas (R407C) , I just retrofitted a Walk in cooler with it , So far so good
