Where to buy CO2

[CHILL_OUT]

I just started working HVAC and I went through my first tank of CO2 today. Only trouble is, I don't know where to get it filled! I live in the dupage (illinois) area. I'm headed over to willowbrook tomorrow. Anyone know where one buys CO2 refills?

CO2 lasts longer.

Frickin' 'A!

Although my MBK6went dry on my first job...my fault....didn't use a flow meter..just my gauge set.:gah:

Maybe hes just blowing out coils, thats all we use it for..

I understand that but where are you guys getting dry CO2 ?
I would love to switch over because I'm sooooo tired of filling my 80cubic ft. tank :gah:

Good point ! I'm to cheap for that thou :whistle: I use a air compressor for cleaning coils. ;)

That's strange they don't carry compressed CO2.

When I used CO2 20years ago, I'd get it from PG Walker which is now Airgas.

Here you go. They list bone dry??? Looks like the cylinders they use in labs.

Run it through a drier.

your kidding ..right?

class 1 co2 is 30PPM moisture.

To a point, yes, I'm kidding.

I discussed moisture with my supplier during one of our earlier discussions on this. They didn't even have specifications for the CO2 that they sold.

I don't see moisture, in the quantities that we're talking about, to be as big of an issue as a lot of people are making it to be.

The system is open, so we're replacing the drier, AND pulling a deep vacuum.

Where's the moisture going to be?

I put a moisture sight glass on all my 410A installs. My bone dry didn't affect a wet color change.

How ever regular supply house co2 would saturate the LLFD and the pump would never get that out.
