Yea... the downside of going with the CoolBot with window AC for this particular application is definitely the price especially if you have some other options available to you. I was concerned that the compressor on a freezer may not be able to keep up with the demand on a larger area, so i...

Ahhh great... glad to hear your found some 220v fans... I'm not sure i totally follow the first question... sorry about that... so i'll start with #2, and then come back to that one... The material itself is a polystyrene insulation board. I used it as the insulation for the walls, floor...

Hey there Johann..... Sorry about the photo... i'm not sure what i did... heh.. i think i updated the post above with the photo. Please let me know if i messed it up again. :-) As for the fans, here's an amazon link to one similar to the ones i used. 115V-AC-Cooling-Fan-120mm Keep in mind this...

Hey there Johann... I keep telling my self I'm gonna put together a build thread, but so far i just haven't gotten around to it... Here's a photo of it about half way built that may give some what of an idea of what i did. The fans are the black square looking things... there's another one...

I made a similar box using 3.5 inches of the pink insulation board in the walls and 5.5 inches in the floor and ceiling and use a window AC to keep it consistently at 36*F. It works quite well. I used a CoolBot for the AC so I didn't need to rewire the AC at all but others seem to be able to do...

Howdy. I have a 3 chambered cold box that is controlled by 2 ranco controllers and a CoolBot. The top chamber has its ranco plugged into a ceramic pet heater for heat and a fan pulling air in from the cold chamber. The middle chamber has its ranco plugged into 2 fans to pull in warm air from...

For heat, I use a ceramic pet heater like this. Pet heater. I think it might be 150 watts. Also added a small fan blowing on the heater so the fan and heater turn on at the same time. This is in a 2 level insulated box with room for 8 carboys on each level,though sadly it has never been that...

Hey gang... pardon me if this is a stupid question, but is the temp sensor probe from a Ranco controller compatible with 1-Wire by chance? (DS18B20) And if it's not, could you replace the probe with one that had a DS18B20 in it so it would still work as before plus now have the ability to be...

That is a good point.... Though, i'd guess most use glycol jackets as their external temp controller to individually control multiple fermenters and not just controlling the air temp around the fermenters? I could be wrong on that though. I kind of assumed the glycol jackets would have more...

Hi gang.... Is there a ballpark guess as to at what batch size, controlling the ambient air temperature is no longer enough for temp controlling a fermentation well? I used to temp control 5 gallon batches in a fridge with a temp controller and that worked great. Now my brother and i are...

Hey there Reelale... hmmm i wonder if i messed up my description since really there are 3 clamps. What I was calling the small clamp end would be the main housing, and the big clamp end would be the end with the 2 clamps, where the filter piece inserts at requiring the bigger clamp. So i was...

Hey there guys.... I just used the filter this weekend for my first time... After immersion chilling, it was set up like this. BK>Pump>(small clamp end)Filter(big clamp end)>Fermenter. The filter was being held by hand roughly horizontally over a funnel for our first test. It seemed to...

I've been reading about the different types of valves.... Butterfly, Ball, Gate, Globe and such, and each has different levels of flow control... I can buy that.... and maybe this is kinda dumb, but for some reason i can't wrap my head around why that is... I was considering converting all of...

It seems like most people are doing 5-10 gallon batches with this filter. Anybody doing larger batches with it at all? 20 to 40 maybe? From reading the posts, it's roughly sounding like 10 gallons of a decently hopped batch might be about the limit per filter maybe?... that's an assumption...

Hey Johnnyc..... Do you still use your heater like that? I'm looking to do something similar, and was wondering if you've had any issues now that it's been a while. Wasn't sure if having it pointing up vs. down had any effect on the life of the device... even though, i'd think pointing up like...

Just spent my first dollar on this project... Picked up the AC unit from Home Depot... was planning to get the 5000 btu... all they had was the 6500 btu, so i said i'll take it... heh.. It's a Zenith, but i guess, according the box, it's made by LG, which LG is the manufacturer the guy at...

Hmm... that's an interesting idea about angling the ceiling of the bottom chamber to give the warm air a place to go as it rises... hmmm... i'm kinda thinking about perhaps having a small CPU fan run every so often in the each chamber just for the sake of stirring up the air in each chamber a...

Hey there Juan and PurpleJeep.... Thanks for the comments... regarding the possibility of the AC freezing.... Yea... I think you are right if the A/C was just left to run normally on it's own. That's where i was thinking the CoolBot would come into play. From what i've read, it has some...

Hey there gang.... Now while my temp controlled fridge works great, it does seem to have it's limitations.The biggest being "Two 5 gallon batches and i'm done for a while".. heh.. and a single temp setting. After looking over a bunch of others builds, i'm considering something along the...

Hey Gang.... i'm thinking about building a bigger temp controlled fermentation box since i get maxed out with 2 carboys right now... I'm liking what TimWeber has going on with his build thread here . I'm thinking about putting the ale box on top of the lager box to save some space, and have...
