Utilizing a Keg as a CO2 Supply for Moveable Serving!

This system makes use of a cheap inline secondary regulator to make the most of a spare keg (or growler)as a CO2 supply to serve a keg. I’m not suggesting this setup as a alternative in your kegerator CO2 tank.  You continue to want a typical CO2 tank. What this setup may very well be very helpful for is as a alternative for these costly little regulators or injectors and costly (contemplating how a lot CO2 you get) little CO2 cartridges. One cheap buy permits you to pressurize and serve your keg on the go for little to nothing.

Aspect Be aware: I’ve needed to do that for years.  There was a industrial sanke keg that had two chambers.  One was used as a stress chamber and the opposite held beer.  I at all times needed a type of.  The issue was that it was extraordinarily costly and I simply couldn’t justify the expense. This magic little secondary regulator makes one thing related simply attainable.

The {Hardware} That Makes This Attainable…

Kegland’s economical inline secondary regulators! As of this replace there are three variations

• Kegland DuoTight Appropriate Inline Secondary CO2 Regulator with Gauge
• Duotight In-Line Regulator D1046 – DuoTight Appropriate, No Gauge
• Inline Secondary CO2 Regulator – That is the unique model, what I’d name v1. It has no gauge and isn’t DuoTight suitable

Associated: Fingers on Overview: Kegland Inline Secondary Regulator

Improve to Digital!

Kegland has launched a digital gauge possibility that works with their nice inline secondary regulator and BlowTie Spunding Valve.  They’ve additionally launched a DuoTight model.

Main supposed Use… Multi-Stress Serving

Sustaining a number of CO2 pressures in your kegerator provides you the power to… hold kegs at totally different pressures.  This can be a requirement to take care of totally different carbonation ranges. It’s additionally helpful if you wish to pressure carbonate a keg extra shortly, at the next stress, whereas sustaining your customary serving stress on a keg that’s already being served or if you wish to have a utility line for purging kegs and such.

The final choices for pulling this off are…

• A multi-pressure main CO2 regulator – instance. This has two (or probably extra) excessive stress our bodies that enable you set totally different pressures.
• Secondary CO2 regulators – instance. These don’t have any means to connect with a CO2 tank straight. They have to be linked to a suitable main.

Each good choices, however typically costly. Kegland Inline secondary regulators are, comparatively low-cost and provide you with a great deal of flexibility.

This Put up Explores an Alternate Use of These Regulators  Adapting suitable containers to make use of as a stress supply for transportable serving. This how-to options each the newer v2 with gauge and the unique non-DuoTight mannequin.

Different Necessities

A vessel to retailer CO2 (a Keg or Appropriate Growler), tubing and fittings.

Essential: Don’t exceed acknowledged pressures for any of your tools.  I’ll take it a step additional and recommend that you just don’t even get near max pressures.

However first, extra about DuoTight!

Kegland’s DuoTight Fittings are designed to work with EVABarrier Double Wall Tubing.  They provide fast, dependable connections, simple implementation, a wide range of becoming choices and have wonderful versatility.  They’re additionally, typically talking, very effectively priced.  DuoTights are push to attach fittings and require no tubing clamps.

Setup #1, Utilizing a DuoTight v2 With Gauge to Pressurize a Keg for Moveable Serving

This setup reveals a 5 gallon keg being pressurized by a 2.5L Growler – Fingers on Overview

As a result of v2 with Gauge – by way of MoreBeer – by way of William’s Brewing… has a gauge, it’s loads simpler to make use of than our v1 setup (see under). The truth that it’s DuoTight suitable additionally makes it loads simpler to setup vs v1.

This setup is as follows

• 2.5L Growler – Fingers on Overview – pressurized to about 35 PSI – Essential: Don’t exceed acknowledged pressures for any of your tools.  I’ll take it a step additional and recommend that you just don’t even get near max pressures. – Be aware: Any appropriate stress succesful container can be utilized right here. See under for some concepts.
• Carbonator Cap – by way of MoreBeer, by way of William’s Brewing – This piece wouldn’t be wanted for those who’re utilizing a keg.
• DuoTight to Flare Becoming
• Fuel Keg QD
• EVABarrier Tubing
• Inline Regulator with Gauge – by way of MoreBeer – by way of William’s Brewing
• Small Piece of EVABarrier Tubing
• DuoTight to Flare Becoming
• Fuel Keg QD

Like many DuoTight Fittings the 2 DuoTight Inline Secondary Regulator Fashions are suitable with Valuebrew’s locking clips. I used to consider these as non-compulsory, however now use them on each connection. They supply again stress on the collar making a firmer connection and locking it in.

However Does It Work?

This keg was pressurized to serving stress of 10 PSI previous to beginning this check. It produced a very good move fee for a lot of the check. A 2.5 Liter growler reliably served about half this 5 gallon keg. A 2.5 or 3 gallon keg can reliably serve a whole 5 gallon keg.

CO2 Vessel Concepts:

• Though it’s not setup as a stress supply, the pictured growler dimension ball lock (it’s truly 96 ounces in line with my testing) would make a dandy stress supply. You must typically be capable of vend 2.5 or 3 gallons with this Corny Keg – 64 oz Ball Lock Keg KEG443 by way of MoreBeer – Overview
• Any absolutely functioning and appropriately spec’d spare keg you’ve gotten round – See our Keg Offers Roundup for current offers.
• 2.5 and three gallon kegs are good as a result of they’re small and will be capable of simply vend a whole 5 gallon keg.

Setup #2, Utilizing v1 Kegland Inline Secondary to Pressurize a Keg for Moveable Serving

Low cost Inline Regulator – by way of MoreBeer | by way of Amazon – Be aware: The unique v1 model shouldn’t be DuoTight suitable. It additionally doesn’t have a stress gauge.

Right here’s the setup.  The left keg is the crammed keg, the proper keg is the stress supply.  A gasoline to gasoline jumper connects the 2 with the inline secondary regulator within the center.  Be aware that the inline does have a move route, there’s an arrow on the facet to let you recognize which means that is designed to move.  Additionally, though these are ball lock kegs, you might simply as effectively use pin lock kegs.I charged the two.5 gallon ball lock keg (stress supply) utilizing my kegerator CO2 tank and regulator.  The regulator maxed out at 50 PSI.  Essential: Be certain each part in your setup is rated for the quantity of stress you resolve to make use of.

Does it work?  Serving 5 gallons utilizing a 2.5 gallon keg as a CO2 supply

Right here’s the setup.  The shorter keg is the stress supply.  There are two 5 gallon kegs.  The one with the tap accommodates 5 gallons of water, I’ll name that the “beer keg” any further.  The opposite 5 gallon keg is there to obtain the check liquid.  There’s some additional stuff right here.  I’ve a ball lock carbonation lid on the beer keg with a digital spunding valve on it.  The stress supply keg has the next PSI gauge on it, linked to a liquid QD.  These gauges are to watch the check.In the beginning of the check the beer keg was pressurized to about 10.2 PSI.  Virtually talking, you might use a decrease stress.The check in progressCheck accomplished.  5 gallons served utilizing a spare 2.5 gallon ball lock as a CO2 supply.  Whammo.A stress studying after the serving check was accomplished.  To ensure that this to be actually legitimate, the 5 gallon keg ought to be about the identical stress after because it was earlier than.  It learn 10.2 PSI initially of the check and 10.3 PSI when the check was accomplished.The gauge on the two.5 gallon stress supply keg went from 50 PSI to about 12 PSI.  50 PSI x 2.5 gallons is about proper to serve a 5 gallon keg at a ten PSI serving stress,  This might have served a bit extra, possibly one other gallon.  You would stretch this identical quantity of CO2 out to serve 2 x 5 gallon kegs for those who decreased the serving stress to five PSI, which is an affordable stress that you just would possibly need to use anyway.  50 PSI x 5 gallons ought to be capable of serve 2 x 5 gallon kegs at 10 PSI serving stress or about 4 x 5 gallon kegs at 5 PSI serving stress.

Setting the Stress on the Inline Regulator (No Gauge Fashions)

Since these don’t have a gauge, you want some kind of a gauge to make use of for tuning within the stress.  The gauge doesn’t have to remain linked, it’s solely used whilst you’re setting the regulator.

This can be a good utility of a Spunding Valve

How a lot CO2 did the stress keg maintain?

From my publish, Kegging CO2 Use Estimations and Calculations – We will use the The “weight of CO2 used for serving a keg” system to estimate this.  That system is (Serving Stress + Atmospheric Stress) x 1/2 x Keg Quantity

So, for this 2.5 gallon keg at 50 PSI, these numbers could be…

• (50 + 14.7) x 1/2 x 2.5 = 80.87 grams or 2.85 ounces

Serving estimates: 1 x 5 gallon keg at 10 PSI serving stress, 2 x 5 gallon kegs at 5 PSI serving stress

For a 5 gallon keg at 50 PSI, these numbers could be…

• (50 + 14.7) x 1/2 x 5 = 161.74 grams or 5.7 ounces

Serving estimates: 2 x 5 gallon keg at 10 PSI serving stress, 4 x 5 gallon kegs at 5 PSI serving stress

Value Financial savings!

Past the {hardware} financial savings of utilizing this low-cost inline regulator for this function, this method ought to prevent cash on CO2.

MoreBeer’s CO2 Injector makes use of 16 gram cartridges.  As of this posting these price $10 for six.  That figures to $1.67 every.  You want between 2 to five cartridges to serve a 5 gallon keg of beer.  Let’s simply use 3 for our estimations, that’s lower than the typical of these two numbers.

3 x $1.67 = $5.01 for every keg you serve

Versus The keg as a CO2 supply technique

In my instance the two.5 gallon keg at 50 PSI keg holds roughly 2.85 ounces (the equal of simply over (5) 16 gram cartridges).  2.85 ounces is about .178 lbs.  I pay $25 for 20 lbs of CO2.  That figures to $1.25 per lb.

.178 lbs x $1.25/lb = 22 cents per 5 gallon keg

Lower serving stress to five PSI and you must be capable of serve 2 x 5 gallon kegs with the identical quantity of CO2.  That may be 11 cents per 5 gallon keg

Aspect Be aware: You want about 29 x 16 gram cartridges to get 1 lb of CO2.  At $1.67 per 16 grams that equates to about $48 per lb of CO2.  Which means 20 lbs prices about… $1,200.  I pay about $25 for 20 lbs of CO2 by way of tank trade.  That is for the aim of illustration solely, I’m not suggesting anybody makes use of these in that amount.

How about serving your kegs for $0 CO2 prices?  Preserve studying…

Execs and Cons to utilizing spare keg as a CO2 supply for transportable serving

Downsides: Measurement and portability are what come to thoughts.  As a substitute of a handheld dimension setup, you’ve gotten an additional 2.5 gallon or 5 gallon keg.

Upsides: If in case you have a spare keg, the prices to implement this are very low.  It also needs to get monetary savings on CO2.  There may be additionally a comfort issue.  Serve a whole keg with out swapping out co2 cartridges.

How about $0 in CO2 Prices to Serve Kegs on the Go??

With the proper fittings, you possibly can add a Schrader kind valve to your keg [See: Adding a Schrader Valve to a Homebrew Keg].  Doing so permits you to use your air compressor to pressurize the stress keg.

Essential: It’s essential that you recognize the stress rankings of all the things you’re utilizing.  Don’t exceed acknowledged pressures.  I’ll take it a step additional and recommend that you just don’t even get near acknowledged pressures.

This system includes utilizing your compressor to fill the stress keg, utilizing atmospheric air to serve your keg. Compressors may additionally probably expel non meals grade lubricants. I’d recommend contacting your compressor’s producer to inquire about your particular mannequin.

Sure, this may trigger oxidation given sufficient time.  No, I’m not recommending this for any long run association. 

When you’re positive you’re going to undergo a whole keg shortly. Shortly to me means beneath a number of hours.  Oxygen will trigger oxidation, however these results ought to be slim to none within the span of a brief time frame.  When you aren’t positive the beer shall be consumed shortly, use CO2.

This keg has a stress ranking of to not exceed 130 PSI.  Each the lid and the keg are stamped with that ranking.  My air compressor has a max stress of 125 PSI.  Despite the fact that the vessel itself is rated for 130 PSI, the PRV began to noticeably vent at about 90 PSI.  The keg finally leveled off at about 85 PSI.

I’ll use my CO2 estimation system to estimate the quantity of pressurized ambiance this keg is holding.  Unsure if that’s as relevant, however my guess is that it’s nonetheless a legitimate estimation.

(85 + 14.7) x 1/2 x 2.5 = 124.63 grams or 4.39 ounces

Conclusions

This economical inline regulator is a superb little piece of apparatus.  Past it’s typically supposed use of letting you simply serve a number of pressures and carbonation ranges, it let’s you set spare kegs in use for serving on the go and saves you cash on CO2.
