Hi !

Hapy new year for every one !!

I have a question,

Do you know if the use of CO2 in cascade applications must be necessarily anhydrous ?? Why
IF yes, what's the tolerance of water in CO2

Best regards

Yep, don't worry you'll get there.

You can always type out a URL with the odd space in it such as...

www . refrigeration-engineer.com

Then people can cut and paste if the wish. :)

Thanks !

But do you know if it's possible to put CO2, for exemple with high level of water (100 PPM) above the maximum solubility limit (22 PPM) and dry it after with filter driers !
Is it to late ! The POE oil is it rapidly contamined etc ...

then just one advice...

wen your system is contamined:

co2 out... clean your system... dry it (vaakum) and refill again...

otherwise you will have a lot more of problems with this unit...
