"New" R507/R404 replacement
Has anyone heard of a "new" R507/R404 replacement? I have heard the blend will be changed to replace the R134a in the blend with I believe it is R123 and therefore lowering the GWP to less than the R407 gases but keeping the same properties. Anyone heard anything about this?
Thanks
