MK:
Air, density about 1.2 Kg m3, Argon about 1.6 Kg m3, galden ht230 has a molecular weight of about 1000, so ~26kg per m3

I think the argon will be superfluous.

I have a 5 litre tank for my wine hobby  ;)
If I remember correctly (couple of years back) you buy the tank for around 100 euro's and next time only pay the refills (you exchange the cylinder for a filled one) costing 18 euro's or something like that. Only problem is safety if it leaks in a closed environment there will be no air to breath. But than if you have a small cylinder this would not pose a big problem.

What do you exactly mean, superfluous?  :-// Google translation says "not necessary",  but the argon prevents the oxydation if you use simple hot air reflow and do not use galden. Yes if you use galden Argon is useless.

Good to see that not everybody gets raped on industrial gas pricing like we do in NZ.
Bottle hireage ~$120/year
Re-fillable bottle purchase $500 up
2 m3 fill ~$80

Hence the reason behind my statement

.

So what is an educated estimate of the m3 of vapour from 500ml of Galden?
Cause you can't see the stuff, how big might a suitable vessel need to be?

Or is this of little concern as it will be ALL temp controlled?

From the datasheet linked above:


--- Quote ---The process is extremely fast and efficient since the
heat transfer coefficient of vapor condensation is
about ten times (10x) faster than hot air and about
eight times (8x) faster than infra red heat.

Doesn't that fascinate you, it does me.

I assumed people wanted to use Argon and Galden, as argon by itself will not have enough thermal capacity/conductivity to do the job fast enough.
