Chemically stable.
Purity can vary depending on the Country supplying it.
Dangerous if there is a significant leak as it displaces Air.
Suited for Cold room applications. Useless as a refrigerant in Freezer rooms.
Liquid charging only. Reckon i read the same report Rob.:)

I remember going into FSW and asking for a bottle of R407C and a bottle of R718....
Blank faces all round ;)

There are that many people flogging their snake oil,
there must be a magic solution out there, one that
does not rot your livers, corrode the system and does
not kill all the fluffy bunnies in the fields and clouds in the sky.

I'll keep looking, someone is flogging an additive that guarantees
20% improvement in efficiency.

:D
