R407C Heatpump

[2v6]

Hello Everybody,

I'm "new" in refrigeration.
I am making an experiment with compressor unit charged with R407C.
What is the limit of the work temperature for the gas?

Please excuse me if the question is out of sense!

There ain't no upper limit for the gas itself...

Having said that, when the compressor's oil reaches about 110C, it start to break down.

And the higher the temperature the higher the pressure will be.
