Hello, experts
I use for work R404A from cylinders.
Each cylinder contain 10.9 kg of refrigerant.
In liquid phase its components R125 / R143a / R134a is in ratio 44% / 52% / 4%
When I charge refrigerator ,
amount and pressure of refrigerant in the cylinder will decrease ,
and once some components will vaporize in cylinder,
and ratio between components get broken.
So a substance in the cylinder will not be R404a.

In view of the aforesaid let me ask some questions:

How much kg of refrigerant I can take from cylinder ?
What should I do with residue blend ? Can I use it for charging?

Thanks for any advice
