CO2 TanksCO2 tanks have at least three popular uses: 1. Presurizing Beer Kegerators. 2. Paintball cylinders refillers. 3. Air tank for tire inflation and power tools with off-road vehicles.E.g. Power Tank: $350 at ExpeditionExchange, OffRoadAir: $230 at 4x4rockshop and Outback Air $290 at rockcrawler.com. Equivalent to most powerful compressors (see trip list). Or you can get a tank on e-bay or BeverageFactory.com for $85-100 and a regulator (Fixed 150 psi. $25-35, Variable 0-200 psi $85-125) (See: 4x4rockshop, Williams Balloons (800.235.4112). 20 ft or longer Polyurethane coiled air hose for $10-36 at: Grainger > Pneumatics & Hydraulics > Air Compressor Accessories > Portable Air Tank Conversion Kits Hose with guage $32 at Central 4 Wheel Harbor Freight Tools Auburn Blvd. and Garfield has hoses, regulators and connectors. and bracket ($45).

DOT approved tanks are typically rated to 3,000 psi. ___________________________________________________________________

http://www.breworganic.com/index.asp?PageAction=VIEWPROD&ProdID=571 These brand new cylinders will give you years of service. We ship these cylinders empty, so you will need to have it filled before using (most welding shops or fire extinguisher service stations fill CO2 cylinders). The 10# cylinder will cost $10 to $20 to fill, and will dispense 12- 18 kegs. Our cylinders are guaranteed to have at least 4 years of service remaining before a required 5 year pressure test (this can be done by most CO2 filling stations). Regulator in picture is sold separately. ___________________________________________________________________

The regulator runs into a Dayton time switch. > Any help would be greatly appreciated. Peace. There may be three gages and two regulators. One gage would read the tank pressure only (very high psi numbers). One gage would read psi from a regulator that controls the pressure coming from the tank (and going to the flow control). I believe this to be the "10-60 and says AR/CO2" you mention. I don't know what AR means. The other would be a gage from the flow control that actually controls the amount of CO2 being released. Flow controls generally read in cubic feet (or liters) per hour (or minute), in your case the "C.F.H.FLOW" means cubic feet per hour. This would be calculated against the cubic footage of your room. Since flow controls work with lower pressures coming from the pressure regulator (in your case 10-60psi) that is usually where the solenoid connected to the timer is located (never hook the solenoid directly to the high pressures found in the tank). The range of the flow control adjustment may be dependent on the psi setting of the pressure regulator. So if you can't get an adequate CO2 release for the timer you use, you may have to decrease psi. I'm hesitant to give info of this type because of the pressures approaching 1,000psi used in the CO2 tank. Pressures of that degree can be VERY dangerous if used with the wrong regulators, fittings, etc. (not to say yours are wrong). An explosion could take your head off, please keep that in mind. You may want to contact Harris for info, see if they got a web site. You never want to release CO2 directly from the tank, always use a proper regulator for CO2. Keep the tank upright during use, and use a small length of chain to keep it from falling over. I believe every 5 years tanks must be pressure tested for safety, the date is usually stamped on the tank. _______________________________________________________________________ http://www.thekrib.com/Plants/CO2/cheap-regulator.html Date: 7 Nov 1994 Newsgroup: rec.aquaria,alt.aquaria,sci.aquaria While waiting for my CO2 tank to be refilled at the local welding supply shop, I was browsing all the cool stuff related to the welding profession. Mixed in amongst the plaid caps and kinky leather face masks was a "FROG" - Flow Regulated Orifice Gauge. It is a preset regulator for CO2 tanks that is set to 22 PSI. It has a little button that either pops out or retracts when the tank is almost empty. This would be an inexpensive way to get setup with a more capable CO2 system. It was marked $22 and is made by Western (Model RP22320).

Frogs, Cables, Vacation

George, the FROG is a little better than that, because it does have a
little pop-out thing that tells when the tank is running low. The label
says "10 minutes left when it pops in". But this is for welders who are
not running it through a needle valve, so I'd guess you probably have a
week before you have to actually replace the tank.
A local store sells their own version fo CO2 injection using these
FROG things and 5# bottles and they report that they have *never* seen
the button do its thing. FWIW.
Regulated Flow Meter (for CO2)
by "John Y. Ching"
Finally I found a gaget called a Regulated Flow Meter which is essentially
a regulator with an integrated needle valve control plus a flow rate gauge
in units of CFH (Cubic ft per hour?). Although the flow rate gauge is not
that useful for our purpose, I found that the integrated flow control is
very smooth and precise. I can get exactly one bubble per second without
doing much adjustment. It is rated for 3000 psi. There is also a
round dial gauge that gives you the pressure (PSI) inside the tank. The
whole thing is made of solid brass.
If you are interested, this thing is made by Victor Equipment Company of
Denton Texas, model # HRF1425-580. I paid C$90 for it, cheaper than a good
regulator+separate valve. And you don't have to look for different
connector and hoses to connect the two. That's about US$65 at the current
exchange rate. It may be cheaper in the States, especially if you have
better welding contacts than I do.

Dave, this setup is being sold by a local shop and works very well, no
matter what the theory says.
> From: Erik Olson <(e-mail)>
The Dupla "Starter Kit" I started with lo these many years ago had a
needle valve that attached right to the CO2 bottle, a check valve, a
plastic diffuser doodad and some silicone tubing. The needle valve
did just fine "regulating" the 900 psi bottle pressure although it was
a tad sensitive to adjust.

FROG update
by Tyson Lee
The only problem I had, was the temperature sensitivity of the needle valve.
The rate would fluctuate highly depending on the ambient temperature. Once
the central was working again, this has become very minimal.
I had the tank refilled after it had emptied in about 3 1/2 weeks. (bubbling
was way too inefficient) I have since tried to bubble it into some bells at
a much slower rate. I should at least get about 6 weeks out of this refill
and more once I get this rate all figured out. In the end, it cost me about
$90.00 for the whole setup.
I simply wanted to let Eric(cause he had asked how it was doing) and others
know that it _is_ working fine despite warnings about having my hand blown
off. It sure beats the hell outta mixing that yeast. Then again, I still
mix it for my other tanks.
Up too late again,

CO2 regulator valve
by "Dave Gomberg"
$35 for a custom rebuilt regulator, ask them for 0-10PSI spring and
2nd stage gauge. It will then be possible to reduce the pressure to
a low enough value to use regular air hose and valves for the rest of
the project, just like with an air pump. No need for a special
needle valve.
