R403a and R403b

[Yo Han]

Good day

I'm new to this forum, so hello everybody.

I have one question which actually got me to register as a member here. It would help me out, and perhaps save the company some money if someone could answer this. So:

What is the difference between R403a, and R403b?

I know the main difference is the composition, but how about performance? How do you notice the difference in composition?

Thank you in advance for a quick reply.

Hi Yo Han and welcome to the forum.

I have no experience of these blends but this document from Bitzer highlights some of the differences which you might find useful.

It is a gas that is on the way out, if not already gone.
