The Glycol Chiller Adapter has worked great with my Grainfather GC2 I'm using it on a Brewtools Miniuni 30+. I mounted the heat pad on the bottom and it works well it will easily heat 6 gallons to about 20 degrees above room temperature.

Great equipment and reliable

The obvious question: Why spent this kind of money on a temp controller when you can get a $40 Inkbird? Answer: Programmability I wanted something where I could have very slow gradual cooling of my lagers. This guy does it well and not sure what else out there can do this at a consumer price point. Remote access via the web is a nice plus many other bells & whistles to geek out on if that's your thing. I don't care about integration (or lack thereof) with other KegLand products so that's a non-issue. Software is a bit buggy at times but is well supported and firmware updates are occasionally rolled out. If you want to do something more than just hold a fixed temp or cold-crash this is your unit.

I connected this to my inkbird and it's working great. The velcro strap lasted for 1 batch so keep some bungy chords handy.

I don't have a chiller yet and I only recently got a pump. Why did I buy this? Well I wanted the option to cool when I expand my operation later. Most importantly though I wanted to transfer wort straight from the boil to the fermenter and cool in the fermenter prior to pitching. This works great! An added benefit is just post-boil I can do a whirlpool prior to transfer and leave 99% of my trub behind! Try that with an immersion chiller! I have 2 mini Brew Buckets and if I'm doing 2 different brews (which is normal on a brew day) I can cool one pop this off and the other lid on then swap this over to the other bucket and cool that too! I'm sure I'll get another when I get a chiller but for my application one is working great!

First use with beer after "testing" with water. Had set high temp cuttoff at 68F with +- set at 1F. Woke up to fermentation temp of 75F (no longer heating anyway) Air temp in room never got above 70F. Will have to see where it stabilizes today but a little dissapointed so far.

It would be nice to have smaller packaging (at a lower price point) since you dilute the PG with water and a gallon of 100% PG will give you many fills if you use a Brewbuilt Icemaster 2 glycol chiller and a Brewbuilt X2 jacket conical (I have a 14 gal model). That said the quality of the glycol appears excellent and provides the ability to chill the glycol/water mix to a low temp for cold-crashing at the end of fermentation.

I'm almost finished brewing a Best Bitter using this to control the temperature and it is working great! Another great product at a great price.

I like the idea of having heating and cooling in 1 unit. I still need to check the accuracy of this since it appears to be a different reading than my Thermapen Mk4

neck of carboy and stopper must be dry Then it might seal.

More beer did a price match for a hard to get item they're always trying to please the customer.

used with small fridge to control carboy temp

I'm so glad I got the chance to buy this

This is well made and performs perfectly. My only complain it minor. It does not fit snuggly around a glass carboy. But it is easily remedied with Duct tape.

Works as advertised. Very easy to use.

Works great in my ferm freezer with the inkbird-308 wifi. Heats nice and steady to keep the freezer near 70 in my cold basement

Works great. Paired it with a ferm wrap in my chest freezer for ferm temp control.

This fermwrap has been exceptional at keeping my fermentation temps where they need to be. Paired with an Inkbird controller thermowell and sitting in a mini fridge I am able to dial in my temps +\- 1 degree.

I have to do my stuff in a garage and in Colorado the temperatures in the winter are too conducive to fermentation. I've had aa 5 Gal glass carboy fermenting for over a month now and it still isn't complete. I put this on about 3 days ago and the fermentation picked back up and I may be done with this batch in a couple of days.

Perfect for controlling temps in my fermentation chamber

It seems to work well enough. The only issue I have is that it doesn't come with anything to hold it on the vessel. Since it doesn't wrap all the way around it could use some sort of strap.

Works great. I can now leave the brewery and watch for my water strike temp to arrive

the coolbot works perfectly. Keeps walkin box at the temperature that I set it at. Would recommend this product to any one considering it.

It's all about temp control and this is perfect

I installed it in a SS fermenter for use with an Inkbird temp controller. No leaks works great

Works perfectly with our new bung and temp controller and thermowell. We have a much better control of our fermentation temperature. Would purchase again but it does seem a little flimsy so I’m not sure how long it will last. We currently have it keeping our Lambic Ale at then proper fermentation temperature.

So far i really like this controller. Has a plug for a heater and a cooler. It’s winter in CO right now so we’re only using the heater plug. Works perfectly with our new bung thermowell and heater. We have a much better control of our fermentation temperature. Would purchase again. Very easy to use and set up with good instructions.

I have been using these for years with a temp controller. This new design on how cord attaches is a great improvement over previous models.

I am a bit disappointed with the heater but it is my own fault. I assumed the heater would be thermostaticly controlled it is not. Apartrom that it works great I just have to keep an eye on it.

I’m not sure if there’s a way they could have designed this differently because a bung is only so big but due to the shape of the cooling parts and the hole configuration punched into the stopper you are limited to s-type air locks or a blowoff tube only. 3-piece air locks (which are my preferred kind) don’t fit this very well unfortunately. Aside from that it’s really a decent deal for the price which saves you a bit of hunting and pecking for DIY piecemeal solutions which would do the same exact job but of course require more work and planning. So there’s the trade off. Worth it in my opinion.

Yes to use and like to check my phone or table to see what temp it’s at
