Okay now with that out of the way... this is a nice and versatile unit. It performs well.

But get ready to learn Celsius if you're in the US, there's no way to set to F. And I'm not crazy about the built in controllers (holding two buttons simultaneous and then holding two buttons again to confirm, then two buttons again to save? Jesus christ), but the unit design is good in terms of what counts - the cooling, the capacity, and the pretty quiet noise. It's about as loud as an older fridge. I wouldn't mind working next to it if I had to. Sleeping next to it wouldn't be fun though.

I've been able to chill 14 gallons down from 70 to 33F in around 1.5 hours holding the chamber at 29F. I could hold the chamber lower but that seems like overkill when mostly this thing is just pumping coolant for 3-4 minutes every hour or so to keep the fermentation stable. As I scale up to having 1bbl size fermenters, and possibly 2-3 of them at a time, I think it will work well even if it might be chugging sometimes. Based on the specs it's right for even a 2-3BBL brewery that doesn't need to cold crash quickly.cters long. Consider whether you would recommend this product and what you like or dislike about it.

Instructions are not the best, but love the chiller. Since I only needed it to chill the all in one combo works well

Works well. but manual is missing one important hint.
Glycol is not glycol . activated glycol, this stuff with anti corrosives is needed. Both can be food grade. If you use only destilled water mixed with glycol , then you still have an autoprotolyse. Means the water is without ions and can corrode the copper tubes easily. Buy the glycol with the inhibitor..it is the same price..but buy it.

I bought this to chill my 1/2bbl Brewtech unitank and 20 gallon brite tank and it does an excellent job. Can cold crash 17 gallons down 35 degrees in about 3 hours and with two more open lines I can’t wait to get more tanks!

As I’m typing this out I have 2 lagers fermenting at 10C and I just kegged an ipa that i cold crashed at 3C so yes it does do what I need it to do. That being said when I first got it there was a leak because 5 of the 8 disconnects inside were not tightened properly with hose clamps. It was an easy enough fix but another problem is that one of the 4 pumps doesn’t seem to work. Again this isn’t a huge deal for me because I have only 3 fermenters but still when you pay almost a grand on a piece of equipment you want it to work properly!

Awesome and affordable. Pumps inside so no external stuff. Held temp fine. Only drawback was no instructions came with it. Went to YouTube and watched videos. Still not sure capacity of water/glycol. Put 7 gallons it.

Very easy to setup, definitely get the extra hose and make short like loops to test the machine, stays very cold and very quiet. I am so far very happy with this

Real rating is 3.5.
It can keep multiple tanks very cool and I live the built in sensors. It has definitely helped me up my lager game for sure.
Price is fair.

Had issues with some of the senor inputs being very loose needing some glue.
It will make an annoying sound unless a sensor is plugged in...even if you "turn it off" I find this annoying because I would like to store the other sensor cables away when I'm not using them.
The master glycol temp controller (stc 1000) on the bottom went bad on me twice. Moorebeer was great about replacing..but annoying. The one time is nearly froze the glycol which I'm sure would have damaged the system. I won't be leaving it on while I'm deployed...thats for sure.
Works as advertised. Could be made with better parts...little worried about longevity on this unit. But we will see.

I was surprised by the quality and features of this chiller. The only drawback is that it only reads temperature in Celsius. Love the temperature control I have now.

When I received it one of the temperature displays was not working. luckily I'm handy and was able to fix it without too much of a problem. Overall it works great. I wish there was a switch underneath every display to shut them off and on other than that I like the unit and it's a great price compared to other chillers

This is a great unit. It seems to be well built, it runs quietly and is easy to operate with a little practice. What drew me to it over the other models is the integrated pumps. However, unless something has changed since my purchase, the instructions that come with it are inadequate to say the least. I recommend downloading or printing the PDF manual from the More Beer website and reading it thoroughly before playing with your new toy. That being said, these instructions are lacking as well. Neither mention putting the drain plug in before filling the bath, a rather important step, and there are a few other recommendations I would make that you won’t find in the manual. First, before you fill the bath or plug it in, cut four short pieces of silicone or vinyl tubing and connect each pump outlet and inlet together. This will prevent you from blowing glycol all over the floor if one of the pumps accidentally kicks on. Second, change the set temperature set point of all four pumps to at least ten degrees above the highest ambient temp of your brewery when not in use. Again, to prevent the pumps from inadvertently coming on. The third point pertains to the glycol/water ratio. The instructions recommend a 20% glycol solution, but say nothing about the bath temperature. The 20% solution will probably be fine if you’re not going to run your bath temp. below 32 degrees. I did some online research prior to my purchase and learned that most breweries run their bath temps at 27-28 degrees f and recommend the glycol solution freeze point be 20-25 degrees lower. ie, 27f bath set point, 2f-7f glycol solution freeze point. This translates to a 33%-35% glycol ratio. The reason for this is that when the unit is under load, say during a cold crash, the compressor runs constantly and the coils drop well below 0 deg. f which causes them to become encased in ice which lowers efficiency. As a test, I did a trial run with 23 gal. of sanitizing solution. (27 gal. Blichmann fermenter in an insulated box). I started with a 25% glycol ratio with a 27f bath. I dropped the solution to 68f and held it for 24 hours, then cold crashed to 45f and held another 24 hours. After the first 24 hours there was about 1” of ice around the coils and after the 24 hour crash, that had more than doubled. So I warmed the bath to melt the ice, drained off one gallon of the 25% solution and added a gallon of glycol to raise the ratio to about 35%. The next weekend, I brewed and fermented my first batch. There was no icing during the 5 day fermentation. Immediately after the 2.25 hour drop from 68f to 45f, there was .25”-.5” of ice on the coils, but this melted within 8 hours of the temperature leveling off, and there was no further icing during the 5 day cc. The test cold crash from 68 deg. to 45 deg. took 2 hours 50 minutes and the beer took 2 hours 15 minutes, which speaks to the efficiency of the proper glycol ratio. I’ve had the Blichmann conical since they first came out, and bought a More Beer heated & cooled about 7 years ago. Don’t get me wrong, I love my More Beer conical, but it takes a long time to cool. With the addition of the cooling coils to the Blichmann, the Brewbuilt cut my cold crash time by 80%-85%, and, in the hottest summer months, I usually can’t get the More Beer below 48 deg. The glycol chiller held it at 45 deg. no problem. You will need to insulate your fermenter as well as possible or keep it in an insulated container of some sort.

If you have the ability to add coils or rods to your fermenter and you have the money, I would highly recommend this chiller, just do your homework first. Bottom line, this is the best addition to my brewery in years.

Cheers

Aside from very minimal documentation it’s working great!! Took a shower in glycol because all the pumps came on when I first fired it up. Cheers!

Instructions could use some updating. Had a difficult time setting temps but once you figure it out not bad. Overall a good product

So I wanted to move away from the space of the garage fridge in my home in Arizona, so I decided on this unit for the price because it came with the pumps and probes.

I modified my two SS Brewbuckets by adding the temp twister cooling coil and using full-size keg insulating jackets to cover them. Coils are connected with quick connects with flow stoppers. I plan to do a 3rd fermenter set up.

The 4th line i use to chill water for wort chiller. Same quick connect lines into an old 3/8 in SS wort chiller into a 6-gallon insulated bucket. At the beginning of brew day, I set that up and make it as cold as I can. When it is time to chill, the water can be the mid 30s and use another pump to re-circulate the water to chill beer. The system has had the capacity to manage the heat exchange so I can minimize water waste and stay in the garage while brewing.

Is this thing an investment, yes. I think in the long run, it will be worth it in the increased capacity to have 3 fermenters going to decrease the water waste from chilling beer as the footprint is small.

I was really hopeful when this thing came in, despite the lack of instructions that everyone talks about. After some research it looked like I had it all figured out so I went for it. When the unit came in, the first impression I got, was that it was a used unit or just really poorly put together. All the displays and temp sensor plug-ins were loose, so I had to hot-glue them back on. After filling it up, the back drain started leaking, and one of the front ports as well. Got the back one fixed with some extra plumbers tape, but the front port is still leaking, can't fix it at all, though I feel like a brand new unit shouldn't require all of this work. Now I never get worked up about anything this much and don't mind adjusting, fixing a thing or two if it got damaged during transit but this is too much. So much for cold crashing this weekend. I'd recommend you stay away from this POS and spend your money elsewhere.

Seems to be cooling well and good value.

Caution however. The instructions are very abbreviated and Step 2 is to locate and fill the glycol/water reservoir. It would have been helpful to remind you to put the cap on the glycol drain tube at the back of the unit, and how to attach.

After cleaning up a gallon of glycol from my garage floor, I ordered two more gallons and now think I am ok although I am only hoping I put the plug on properly. No instructions for that.

Very limited instructions. Impossible to find more info on internet even through manufacturer’s website. It does make glycol/water mix cold and it does circulate, so I guess it works... for same cost could have bought Blichman and I kinda got buyer’s remorse.

I picked this unit because of the internal temperature controls and integrated pumps. (saves you $240-400 over other similar units) MoreBeers support was great I had a few questions about the unit and even during the Coronavirus lock down when all their people where working from home, they went out of their way to answer my question and finding the answers to my questions.

The unit is well built and looks great!

Make sure you download the online instructions as the ones in the box aren't that great.
