R740 Refrigerant
Hi Guys,
Hope you can help me.
Can anyone tell me the purity of R740 Argon refrigerant, I have brought Argon N-6 grade which is 99.999995% pure and is bloody expensive. which by all accounts is pretty pure.
Does anybody know if R740 is purer than N-6 grade.
Kind regard's
Graham

Argon N-6 is 99.9999 pure.

The number refers to the purity.
The Linde booklet shows the different grades if you want it in writing, see the Argon page.

Because I still lay with refrigerant, so I do not know more details about R470. While I personally always use [advert removed] for my home cooling
