As I worked through my keezer build, I found myself questioning whether my insulation was good enough, if my keezer was cycling too often, etc. I'm sure you saw my plentiful threads on the subject

I thought it might be beneficial for others to have a thread compiling information of people's builds so others have a way of comparing their setups. Is it ideal, less than ideal, or better than ideal? If you guys don't think this is beneficial, I won't be offended :)

For example, I'll start:

Fridge/freezer type: Frigidaire 7.2 cu chest freezer
Build: 1.5" plywood collar w/ 1.5" foam insulation
Fan: nope!
Controller: Johnson A419
Cut-in/cut-out: 37*, 43*
Probe location: Taped and insulated against keg
Cycle information: Cycles on roughly every 2 hours for 20 minutes (78* ambient)
Thermal mass: I have 2 filled kegs providing thermal mass inside the freezer
 
Fridge/freezer type: Frigidaire 13 cu chest freezer
Build: 6-tap T-tower, no collar. Replaced glass batt in lid w/ 1.5" XPS foam board
Fan: 120mm stirring fan, 40mm tower cooler, 80mm Eva-Dry driver
Controller: MH1210
Cut-in/cut-out: 34°F/35.5°F
Probe location: Velcro strapped against keg w/1" thick foam insulation
Thermal mass: 7 kegs averaging 4 gallons (today)
Cycle information: cycles every 3.25 hours for 20 minutes w/80°F ambient

Cost to run: 15.7 cents per day

That's according to my kill-o-watt meter over the entire 217 days since this keezer was built, and includes the freezer, MH1210, 19" VGA tap list display and the Raspberry Pi based system that runs and monitors everything (and plays music when you come in range ;) )...

Cheers! :mug:
 
Fridge/freezer type: GE 5 cu chest freezer (It's not the size... It's how you use it. Lol!)
Build: 2x10 pine (painted and silicone sealed) No insulation. Collar attached to freezer. Lid kept normal with original seal and attached to top of collar.
Fan: Two 120mm computer fans (1 blows up/ 1 blows down. Friggin tornado!)
Controller: Good ol' stc, baby!
Cut-in/cut-out: 37°, 34° (I prefer a bit cold and carby)
Probe location: Taped and insulated against keg
Cycle information: Cycles on roughly every hour for 8-10 minutes (75* ambient)
Thermal mass:*Usually three 5g kegs at 3/4 full. If I only have two beers available, I fill another keg with just water.
