Title: Wanted: Pure Oxygen setup for beer oxygenation
Post by: molc on September 14, 2015, 09:28:11 AM
As it says on the tin. If anyone is selling on their kit at a good price, I'm interested, before I go off and get all the parts to build one myself. The guide at http://www.nationalhomebrewclub.ie/wordpress/oxygenating-wort-with-pure-oxygen/ looks good for making one.

What about the crowd in west Dublin, Rossa got gas there recently as well? All you need then is the diffuser which I think HBC sell or norcal on eBay and a flow gauge from ebay
Go with the finer diffuser

You mean Wholesale Welding Supplies? That's where I was going to get the bits and pieces - just checking here first in case someone was offloading theirs for cheaper first.

Was going to get a 0.5 micron diffuser.

I just built one of these recently. I got the oxy and regulator from http://www.wholesaleweldingsupplies.ie
The stone I got from a HBS when I was in the states. I also added a filter (also from the HBS) just to make sure. Tubing was silicon 1/4" from the HBC. I wrapped tape around the end of the regulator to make it fit onto my 1/4" tubing (and secured with a clip)

I didn't bother with a flow meter. I turn it on enough to see bubbles then dial it back a bit. My last brew started VERY quickly and kept going for a couple of days than I'd get with just shaking

I would recommend a flow meter as  you need 1l a minute for 45 Secs for a 1050 or 90 secs for a 1-1.1 monster the reg can deliver up to 5l per min so you run the risk of killing your yeast with supersaturated 02 wort .
The pros aim for plus or minus 3-5 ppm and I know of one where it's 1!!
Remember always as well O2 first for the same reason.
Please correct me on this but off the top of my head;
Normal sloshing gives 8ppm
Aquarium pump 12-15
O2 21-24ish

Aquirium pump and crazy shaking will give close to 8ppm, I believe, which is why you want 02 for anything decent.
@Nigel, sure we can chat about it at the next ncb meet and sort out an order.

dreadful that I use google to find this!! Thanks Dr Jacoby for writing in the first instance :)
http://www.nationalhomebrewclub.ie/wordpress/oxygenating-wort-with-pure-oxygen/

Edit this was the original article I was looking for
https://www.wyeastlab.com/hb_oxygenation.cfm

And so as not to derail the original thread hope somebody can help if not you know how to get sorted, I also found you this
http://www.ebay.ie/itm/LZQ1-7-Oxygen-Flowmeter-with-Control-Valve-for-Oxygen-Air-Gas-Conectrator-/221839962405?var=&hash=item33a6b13125
I have the one 3 in from the left but the one on the far right looks sweet. Important thing is you can read 1L/min easily

Cheers John. Looks like it's a build, so will hook up with Nigel and get the parts in.

With a few mins on mr google and aliexpress I reckon I'll be knocking up one these when we get the kit.

A bit of plumbing and one of these and jobs a goodun.

Very hard to calculate your ppm with an inline setup like that. Much easier to hit it with 30 secs oxy at flow rate of 2 litres per minute on your oxygenation wand. In my opinion.

So I was looking at getting a setup as well, but the prices have gone up lots since the last group buy, would there be interest in organising one? the  oxyturbo cylinders have gone from €19.50 in the group buy to €35, and regulators have gone from €23 to €31 so a group buy would help knock off some of that price increase.

The increase is directly related to Stg exchange rate as they are coming in from the UK, start a new interested GB thread?

I'd be interested

I payed 67e for two more bottles on 28/07/14 (even though I organised the GB with them & knew the previous price - no budging on cost) That was well before the euro took a shit against GBP? Gouging?

Maybe not actually. It was july last year when things started getting hairy.

Here is a belgian supplier:   http://www.dekatools.be/oxyturbo-eenmalige-zuurstoffles-voor-ot115-turbo-90-1-l.html

Maybe contact them for a GB price.
Title: Re: Wanted: Pure Oxygen setup for beer oxygenation
Post by: molc on October 27, 2015, 03:07:50 PM
Paid the same recently for 2 bottles, so looks like that's the new price from the old GB supplier.

So thats about €27 and the Belgian is €28.10 so not much in it.

Only problem with shipping these will be the compressed gas regulations which might up the price.

But there is always NHC express!
