Purchasing Gases Online

[Dementor]

Anyone know of any online stores that sells gases? I specifically searched on ebay for R-507, but came up with nothing. Any suggestions rather than a local HVAC store?

[wdrzal]

buy off local wholesale stores, the shipping will kill you.

[Stewie007]

Will they sell to ya without a license, btw?

[Dementor]

Eessh... Just called a local HVAC supplier and they charge $255 for 25lbs of R-507... Thats kinda steep.

[Dementor]

Will they sell to ya without a license, btw?

No they won't. Sorry

stewie he got a license

It's pretty scary what you can get on ebay without a licence.

In the UK, you need a special handling licence for hydrocarbon refrigerants. Just having a tech licence isn't enough, there are a few specific courses you need for 'em. That's anything from R600 all the way up to Ethylene. Without it, you can't buy it. Period.

Funny enough, except on Ebay, where they'll sell it to anyone at bargain prices :rolleyes:

Funny old world, ain't it?

[wdrzal]

some gases are pricy, I don't use that one so can't speak to price.

[Dementor]

Haha! I just noticed something. He looks like he was about to rat them out.. ahah.. Nothing bad, its just funny. But no, I do have a license. But still, the prices are steep.... Would everyone agree r-507 is a good one for a single stage? Or is there a nice substitute thats gives a nice bang for its buck? (Good quality for the amount you pay.)

[runmc]

$225 is the going price for r507 Actually that sounds a little cheaper than I bought it for last time :mad:

These people use to sell r507 (http://store.lenzdist.com/section.php?xSec=42&xPage=2)

[Dementor]

Hmmm, so what would you consider as a nice substitute that isnt digging in too much to the pockets. I really dont have a limit on cash, but since this is my first trial, I want to keep it low budget until I get a working one up and going. Also got to get myself more familiarized and used to them.

[runmc]

Propane - r290 :eek:

[Dementor]

Hey run, incoming PM.

But isnt propane at the bottom of the food chain of gases. They dont even require licenses do they? Just wondering. Thought that the better gases that required licenses where able to cool better, even though propane does reach temps of -50 from what I've heard.

[wdrzal]

try r22 then non flamable, as cheap as they get

r290 is not sold in the usa as its illegal, keep in mind fuel grade propane is not r290

fuel grade propane is not dehydrated to the degree of r290

well just like holland :P we all know you can buy weed here. Its legal to smoke weed inside your house and in the coffee shop. So its legal to sell weed (if youre a coffee shop). But if youre a coffeshop its illegal to buy weed, and also it is illegal to grow weed and sell it to the coffee shop. strange world he ;)

Thank you sir ;) I learned something there. Good suggestion Walt.

At one time you could buy small cans of r22 at AutoZone. I think I still have a couple in my garage.

Here (http://store.lenzdist.com/section.php?xSec=42&xPage=2) are some small cans of r22

So, can't I use some regular propane (from the propane can that I use in the kitchen) as oil carrier?

[Dementor]

Unless I find a easier way or cheaper, Ive already picked out someone who is willing to help with some R-507. If someone is willing to helping me out and selling me about 5lbs for it for even cheaper than this person, pm me a price tag.

[n00b 0f l337]

Wait I always thought propane did work?

[runmc]

Propane works great!! Problem is, it's flammable.

[Dementor]

Well I will be working inside an apartment til i find a nice space to to call my shop. So i really dont mind it being flammable, but due to the fact that other people live here, Id rather just not. Ill just get the r-507 I guess.

[wdrzal]

Wait I always thought propane did work?
many people have used it here with much success, but it does contain moisture in varying degrees that can cause problems.

[Dementor]

Propane wont be my gas of choice. Unless Im going to make a low budget phase one of these days. But for now, ill stick to a can of r-507 :-p

[jinu117]

I myself bought "can" of r404... wonder how long it will last me lol.

[Dementor]

5lbs? I was told you can use it to gas up 15 of em suckers if you know how to do it right.

[jinu117]

nah.... 24lbs can is only what you can get for r404a...
Not much different for r507 if I am not mistaken.

[Dementor]

Hmmm... Well Im getting r-507 by the 5lb's from someone. He is charging me a set price per lb.

[Stewie007]

stewie he got a license

How was I supposed to know that? :p

How tough is it to get one?

Very easy actually. Its a open book test... A few hours of reviewing is enough. I would even saw its possible to pass without reading, because its a open book test. But I do want you to read it, since its very interesting and a MUST when dealing in this field of operation! Good Luck!

[jinu117]

D... go take 609 test ASAP. You really "Can't" buy the gases in small qunatity unless you have 609 or universal 608... (more like 608 part III)

[Dementor]

bah... Im getting it from someone... Not really a company or anything. Im sure he will be more than happy to give me the 5lbs with or without the 609 cert.

I mean, I dont even see the point of needing a 609 cert for a small dosage. If anything, you should always handle with care any types of gases no matter what the amount, but smaller dosages are always a little bit easier on the person, especially new people. Im sure when people start off they would rather prefer a 5lbs of R-134a rather than 30lbs of it. You should always be careful of the gas, but getting a new cert for the same gas in small quantities is just useless to me. I mean, I do also understand that smaller cans are usualy used for cars, but come on? As far as a 609 cert for small cans, it should be made this way.

For example, if CFC's were still manufactured, ex r-12 (which i believe is a CFC)
then people should be required to take the 609 test to be allowed to use small cans of this gas, since it is harmful. Ya know? Not make it the same gas just smaller quantities... To me if anything it should be the other way around. If you want bigger quantites, we have to make sure you know 100% how to handle, process, recycle, and properly dispose of gases, thats where the 609 kicks in. But nope, its not that way.

Sorry if im confusing ya or im maybe not making sense? But yea, thats the way I see it.

[wdrzal]

609 is a automotive cert, 608 is hvac/r there is no canister limatation as to amount of gas you can buy on 608 cert. A 608 type 1 is for med and high pressure refrigerants with systems under 5 lbs.

[Dementor]

Yes, but a type I you are restricted to 20lbs or higher. If you would like to purchase smaller amounts, you need a different Type of 608. Which is almost retarded in my view. Like i stated before, I would understand if you were only allowed up to 5lbs on Type I and work your way up, but to start at high loads of it and needing a additional type to get a smaller amount is rediculous to meh :-p

I work in refrigeration. :) I just don't have or have a need for a license, outside of my dabbling at home.

So then, you just read a few things, take a test, and get a license? How much does it cost.

[Dementor]

The test for the Type I Certificate is $24.99 and can be taken online at www.qwik.com
*You must answer atleast 21 or 22 (calculate how many gives you a 84%)
*If you fail one part of the test but pass the other, then you can retake just one part for a reduced price of $5.99
*The test (608 Type I Certificate) will contain 2 sections each containing 25 questions. You must achieve a passing average of 84% on each.

you can buy ethylene without it and say its for lab work not refrigeration.

of how do you get all the licenses in the uk?

[Gray Mole]

If you contact your refrigeration supplier, most of the time they can tell you...

1) What you need for a given refrigerant.

2) Where you can go for the handling licenses and certification.

General Tech status means you can get most non-combustibles without issue, it's just the hydrocarbons that they have to regulate at the supplier level.

Afaik you still need the handling licence regardless of what you plan to use the Ethylene for.

I thought that's why you used the filter drier while charging.

[wdrzal]

The filter isn't 100% effecient they will asorb a small amount , they only catch a small % each time thru, but if your cap tube freezes it can't circulate any more. So by thinking by installing a filter/dryer your worries are over is just wrong.

[(sin)morpheus]

Oh ok, thanks for clearing that up for me.
