R-404 and R507 are out of the game
It will be a matter of maybe a few years but prices are already soaring.
Any suggestion of replacement for low temp or should I invest in a big stock?

Re: R-404 and R507 are out of the game
I've been using R407F but not tried it in a freezer. Have also ordered a load of R404A for stock as the price just went up 30% here. Crazy times.
Mostly found in Oxfordshire, UK :)

I have been seeing a bit of R290 Propane getting around, its a really good refrigerant.
I haven't done it myself yet but another company in town has been using R290 with R404A comp and TXV.

Retrofitting 404a to r290? Propane what issues does that present glad I am on the guidelines now it's sounds like danger to me!

Think R448A is being pushed for low temp systems, not tried it.

Re: R-404 and R507 are out of the game
R448A should be OK for replacements but only in DX systems, glide is around 6/7°K. Nothing yet for flooded or pumped systems, and probably nothing definitively.

Not for transport refrigeration that's for certain,get the drawing board out I would not put it into a reefer unless if was based close to a fire station!
