Kegerator Beer Line Temperatures & Lowering Foam with a Recirculating Fan

Again in 2014, I had what I’d name a fairly effectively put collectively and balanced kegerator.  Despite that, for years, I had handled the dreaded first foamy pint of beer.  After that pint of beer, beer would pour nice.  That’s till a big delay between pours – in a single day or just a few hours.

A Nearer Take a look at Kegerator Beer Line Temps

The setup.  I’ve two temperature probes in my kegerator.  One is zip-tied to the highest of a beverage line.  The opposite is zip-tied to a can of beer.  That’s how I’ve saved the probe in my kegerator for a very long time with the considering that the mass of the can of beer will assist to stabilize temperature readings and provides total secure and correct readings.  That may is sitting on the compressor hump of my Kenmore Deep Freeze (8.8 Cu ft Mannequin 16932, out of manufacturing).  That places it about mid keg.

Beer Line Temps – No Recirculation Fan

The reason for the issue is fairly clear.  Warmth rises.  Meaning the highest of your kegerator goes to be hotter than the underside of your kegerator.  That hotter beer foams when it comes out.  The tap and shank are additionally hotter.  That heat provides to the issue.

How a lot is the temperature variance?  In fact, it will fluctuate from setup to setup and local weather to local weather.  I used to be comparatively shocked by the temperature distinction in my very own kegerator.

The highest studying about mid keg and the underside studying is the highest the highest of my beer traces.  These are about 22″ aside.  This graph reveals a time limit variance between the 2 of 14.9 levels F.   My beer is concerning the temperature I would like it, however the prime of my serving line is way hotter.  That distinction in temperature causes the primary pint to have an excessive amount of foam.  Pours that occur quickly after the primary are nice.  The tubing, shank and beer are comparatively cool.

Including a Recirculating Fan to Scale back Beer Foam

I selected AC Infinity’s Pre-Wired LS8038A-X 115 Volt AC Fan – additionally for Canadian Brewers through Amazon.ca, as a result of it was moderately priced, received nice evaluations and it’s already setup to make use of AC.  Word: the looks and identify of this unit has modified since I first wrote this textI positioned the fan on my CO2 tank, leaning up in opposition to a keg.

Outcomes!

This graph illustrates the consequences of including the recirculation fan inside my kegerator.  Previous to the fan, the tubing temperature spiked to round 55.4 deg F.  After the deep freeze kicked on, the tubing dropped to round 53.15 deg F.  Not an enormous change.  That averages out to 54.275 deg F.

You’ll be able to see the purpose on this graph the place the fan is turned on.  The temperature drops sharply.  The brand new is excessive 47.3 deg F and the brand new low is 42.13 deg F for a mean of 44.715 deg F.

• Earlier than – Avg Tubing Temp = 54.275, Avg Mid Keg Temp = 38.83, Dif = 15.445 deg F
• After – Avg Tubing Temp = 44.715, Avg Mid Keg Temp = 38.89, Dif = 5.825 deg F

The recirculation fan dropped my tubing temperature by 9.62 deg F (62%).  Virtually talking, that distinction is sufficient to make each pint pour proper.  My first pint pours accurately… I like that!

A glance down.  You’ll be able to see my Eva Dry E-500 (Fingers on Evaluate) standing by caring for condensation.  I’ve heard from others {that a} recirculation fan makes the Eva Dry work even higher.  My kegerator has remained dry (with the assistance of the Eva Dry) since putting in the fan.A glance down my collar.  As you’ll be able to see, I’m no chippie.  Having mentioned that, I spent a whole lot of time engaged on the match and end of this collar.  The tip consequence was good.  If you happen to let the deep freeze door fall shut the ensuing noise, feels like a manufacturing unit seal kind of thump.  I did put climate stripping on the underside to seal between the collar and the deep freeze.  Including insulation to the collar would, presumably, additionally assist preserve temperatures and cut back foaming.

I bought this fan in April of 2014 and began utilizing it quickly after.  As of this replace in August of 2020 the identical fan continues to work nice.  It has been working repeatedly in my kegerator years.  Word – I do use an Eva-dry E-500 in my kegerator to assist deal with kegerator condensation.  See: Dealing with Kegerator Condensation with the Eva Dry E-500.  I theorize that retaining condensation below management might play an enormous half in fan longevity.
