  • Built-in pumps and digital controllers
  • Control multiple fermentation temperatures independently
  • Fill with 20% glycol solution for optimal chilling performance
  • Cold crash with good insulation
  • Perfect complement to BrewBuilt X-Series Conicals

The IceMaster Max 2 is designed to cool fermentations in small vessels. It features 2 built-in submersible pumps with independent digital temperature controllers and can be used with any vessel that has a glycol jacket or submersed cooling coil/rod. Each controller includes a temperature probe that should be inserted into a thermowell in your vessel or can be taped to the outside of the vessel if you don't have a thermowell. The digital controller then measures the temperature of your tank and turns the submersible pump on or off to cool to your desired set temperature. Up to two tanks can be controlled separately with one IceMaster Max 2.

The Max 2 is the perfect unit for brewers with 1 or 2 fermentation vessels. The IceMaster 100 and IceMaster Max 4 are terrific chillers, but for they have far more cooling capacity than the average homebrewer needs. The Max 2 is the most affordable glycol chiller we offer, and thanks to the built-in submersible pumps and controllers, there's no need to purchase additional pump kits to use with your cooling system(s).

The IceMaster can be used with any fermenter that has a built-in cooling jacket, added CoolStix, or a submersed cooling coil. It works well as the cooling source for the following sytems and fermenters.

  • BrewBuilt X-Series Uni+ - the Uni+ comes standard with a neoprene insulating jacket and custom-designed CoolStix that pairs perfectly with the IceMaster. All you'll need is 5/16" ID tubing and hose clamps to connect the inlet and outlet of the CoolStix to the IceMaster—both of which feature 3/8" OD barbs.
  • CoolStix - CoolStix can be added to a wide range of carboys, fermenters, and tanks and the IceMaster works really well in combination. Each CoolStix is available with or without a pump kit; for use with the IceMaster Max 2 you will only need the CoolStix and some tubing to connect it to the chiller.  
  • Ss Brewtech Fermenters and Brites - Ss BME Chronicals, BME Brites, and Unitanks come with cooling coils and neoprene as standard. The optional chilling FTSs will not be needed for use with the Max 2.
  • Spike Conical with Optional Cooling Coil - the cooling coil for Spike CF series conicals is available for purchase independently from the TC-100 cooling system. For use with the Max 2 you will only need the the coil and some tubing to connect it to the chiller.
  • Speidel Tanks with Optional Cooling Jackets - You will need two lengths of tubing to connect the chiller to each tank.   
  • Grainfather Fermenters - Grainfather fermenters have standard cooling jackets. You will need two lengths of tubing for each fermenter.
  • Blichmann Fermenators with Optional Cooling Coil - You will need two lengths of tubing for each Fermenator.

It is always difficult to determine exactly how many tanks can be chilled at one time as it depends on what is happening in each tank, if the tank is insulated, and what the ambient temperature is. Cold crashing always requires the most energy and requires tank insulation. We have experimented with capacities and can provide this general guide based on a 75°F ambient and neoprene insulation. Neoprene provides a modest amount of insulation so you would obtain better results using Armaflex or a higher R rated insulation. 

At 75°F ambient temperature with neoprene insulation, the Max 2 can cold crash one 1 BBL tank or two tanks up to 15 gallons in size at one time to 38°F.

Set Up
In order to hook up the IceMaster to your fermenter or tank's cooling system, you will need 2 lengths of tubing per vessel. All tubing connections should be secured with hose clamps.

  • Length 1: Barb of 1st bulkhead (IN) to cooling system outlet
  • Length 2: Barb of 2nd bulkhead (OUT) to cooling system inlet


  • 2 built-in submersible pumps with independent digital controllers
  • Pump controller reads in °C
  • Temperature controller reads in °C
  • Labeled IN and OUT stainless bulkheads with 3/8" OD barbs
  • Tank Capacity: 17 L / 4.5 Gal. Water Capacity
  • Compressor: 3/8 HP
  • Cooling Capacity: 500 Watt/1700btu/0.14 tons
  • Refrigerant: r134a
  • Voltage: 110V
  • Dimensions: 19" x 12" x 17.5"
  • Wheels not included
  • CE Certified


Note: The new model includes a sightglass that is connected via two plastic Duotight tees.  The tees can be attached onto the push tubes on the front of the unit. The sight glass can be fitted between the two tees and plugs need to be inserted on the outward facing openings. 

Warning: Do not set the reservoir temperature controller lower than 28°F (-2ºC). Running the unit below this temperature may negatively affect the unit's efficiency and has the potential to freeze beer which may impact the finished beer's flavor.

What is the decibel rating for this unit under load? Is is louder than a typical mini-fridge?
Jason Amsden on May 3, 2020
BEST ANSWER: The compressor is not very loud but the fan is quite loud and the sound is at a higher pitch. I would not recommend placing this in a living room or office. Putting it in a garage or basement should be fine.
What kind if warranty is offered, especially for the built-in temperature controllers?

Are there going to be wheels available for this?
brian romanowski on Apr 16, 2020
BEST ANSWER: At this time we do not have plans to add caster options for this unit. I will pass your question along to our development team so they can get started on it. Cheers!
Can this unit present Fahrenheit values?
Jason Amsden on May 3, 2020
BEST ANSWER: It only does Celsius, but I just found a nice Celsius to Fahrenheit beer chart, went on amazon and had a refrigerator magnet made of it. Now I have a handy chart that is right there on the unit.....
Can this be used with immersion chiller to cool wort after boil?
Mark Ingham on Mar 20, 2020
BEST ANSWER: We do not recommend using this to chill hot wort. The liquid coming out of your heat exchanger will be too hot for the compressor to handle and will burn out the machine quickly. We can recommend using the glycol to cool down a tank or bucket full of water that you can recirculate through your wort chiller. This will stop the chiller from being overwhelmed and will still save you water along the way.
What is the optimal temperature to set the main controller to when using glycol solution (not straight water)? I'll be using this with a pair of Spike CF10 conicals (getting all the hardware needed at purchase of those).
Adam Goldberg on Apr 27, 2021
BEST ANSWER: You want to set the controller about 20° below whatever setpoint, or lowest set point, you will be using for the beer. But, you don’t want to go much below that, otherwise you start getting some significant temperature swings in the beer itself.
I need to replace one of the pumps. What's the easiest way to get access to them?
Shawn Garrett on Feb 13, 2021
BEST ANSWER: If MoreBeer can't help you out with this, you can order a pump directly from KegLand. The IceMaster Max 2 is a rebranded KegLand Icemaster G20.
Will this chiller allow me to Lager a brew in my SS Brewtech conical with FTS lid?
Tom Sills on Jul 1, 2020
BEST ANSWER: Hi Tom - the cooling capacity is greatly dependent on the ambient temperature, volume of the fermentation, and whether the fermenter is insulated with neoprene or other material. With that in mind, at 75°F ambient temperature with neoprene insulation, the Max 2 can cold crash one 1 BBL tank, so it should be fine maintaining lagering temperatures for your conical, assuming it's below 1 BBL in size.
Will this work with the SS Brewtech Brew Buckets?
Anthony on Apr 2, 2020
BEST ANSWER: Yes. This glycol chiller will work with any fermenter that has an internal chilling coil or a jacket.
what is the operating PSI of the pump? I am looking to use this with a glycol jacket that is rated for 8 PSI max, will this work with that?
h marc gorfinkle on May 24, 2022
BEST ANSWER: No problem with that rating. The pumps are small. I doubt it would get even half that pressure.
Today I spoke with a friend who had received his Icemaster Max 2 last week. He assured me that the unit can also heat up. I can hardly believe it, but if so: Why is that not specified anywhere? I only know that you have the possibility to connect a heating device which is then also controlled by the internal controller (version 2.1). Does my buddy now have a kind of version 2.2?
Stefan Mueller on Dec 6, 2021
BEST ANSWER: Thank you for your inquiry and we apologize for the confusion. This unit does not come with any heating device nor a controller specifically designated for heating. It is possible to use the controllers with a heating device but you will then not have that controller available for a cooling application. There is no version 2.2 in the works at this time.
I’m using S&S brew tech one BBL bright tanks for flavored seltzer’s and the chiller will not get below 4°C I’ve set at -2 Celsius and it’s still hangs around 4° please advise thank you?
Chris Witzke on Jun 28, 2022
BEST ANSWER: The factory default temperature differential is 2 degrees.
The differential can be adjusted in the Parameters menu. There is an ICEMASTER MAX 2 pdf which I downloaded a few years ago which describes the way to change that. Put a thermometer in the main glycol tack and check the temperature. I have kept my glycol temp much lower than my target fermentation/laagering temp as is seems more efficient in maintaining temp. I have found that the IceMaster's glycol tank to more than adequately insulated to easily maintain a tank temp much less than you are using. Fool around with that number -- I set mine at -10 to -15 -- and see if you can keep the bright tank in an acceptable range.
Where can I download an operation manual?
Kevin Stewart on May 4, 2022
BEST ANSWER: It won't let me include the link. The file download is on the BrewBuilt dot com website.
The help desk at MoreBeer is also helpful since there is missing info in the manual.
How much electricity does this draw? Considering on maintaining ale temps in a garage during the summer.
Kevin Chorzelewski on Apr 8, 2022
BEST ANSWER: Not an exact answer, but there is data on the unit for amperage draw. When I initially received mine, I was impressed on how little the unit's compressor ran in my warm (hot) garage during the summer. It is well insulated. I use a Spike conical fermenter with the neoprene insulating cover, and additionally will cover it up with a blanket or tarp. How long the pumps run will depend on the insulation of the fermenter. I also run the glycol lines inside the foam tubes you can get at HD or Lowes that are used on hot water pipes. You will be happy with this chiller.
duo tight connects for input/output on ice master and eva barrier tubing?

I would like to use duo tight fittings on the input/output on the barbs. What parts would be needed for these connections?
h marc gorfinkle on Mar 20, 2022
BEST ANSWER: the input and output hose barb are stepped so I don't think a Duo tight connector will work directly on the chiller
Can the glycol hose barbs be replaced with quick connects?
Jeffrey Morrison on Dec 16, 2021
BEST ANSWER: You could complicate matters, but just put a short hose on the barbs and install a quick disconnect to that short hose. That allows you to easily revert to just using a hose if you later decide to or if you pass along the chiller to another if your brewing practices change.
Has anyone found an extension for the temperature probe? I only need about 3' more. Thanks!
Jay Nogle on Jan 24, 2021
BEST ANSWER: You should be able to use standard RTD or Thermocouple wire to extend the temperature probes. RTD wire has 3 wires, Thermocouple wire has 2. It is fairly simple to see how many wires are coming off of your controller for the temp probe, order that type of wire, then splice it in between the end of the current wires and the temp controller itself.
Is there a Duotight fitting that will work with the bulkheads on the chiller?

This thing is awesome, I run a 5 gallon fermzilla and a 14 gallon Anvil fermenter on this and after I insulated the hoses I can cold crash and do lagers which is something I’ve not been able to do in the past.
It’s a little more expensive than making a fermenting chamber out of a fridge, but so much more user-friendly in my opinion.

Middle of the road
I used the IceMaster to cool wine fermentation.
Positive: compact, very quiet, works well (only used one pump on 20 gallons of must), easy to assemble and use, easy to store away.
Negative: temp read in Celsius (not really a problem), no casters (when full of 41/2 gallons of cooling liquid, hard to move), both pumps will operate (don't have the option to shut one off), The pumps are somewhat week (very slow flow rate).

Simple and Effective
Overall not a bad product but it could use a few changes.

1. Both pumps are on, make sure you have tubing on both sides even if you aren’t using one. Otherwise the liquid will shoot out and spill every where. Creating a loop with spare tubing helps mitigate that. Additionally I recommend jacking the temp up for the probe super high as that’s the only way to turn the pump off

2. Unplugging a thermometer probe will trip an annoying alarm that won’t shut up unless you plug the probe back into the unit. This also goes with both sides always being on. You should be able to turn off a side if you have only one fermenter going.

3. It only does Celsius. I know I know, just a dumb American here but it is annoying googling what 14.8 C is in Fahrenheit.

4. Easy to set up, but make sure you set it up in the place you’re using it as it has no wheels so moving a full chiller can be a messy struggle

5. Works quickly, chilled wort down from 90 degrees F to 58-60 in about 10-15 minutes.

6. Price is not bad, especially for a two port system.

Overall I would recommend if you’re in the market for a simple and effective glycol chiller for your home brewery!

Unintuitive start, but happy now
Once setup, I've been happy with the unit. I have it running in the garage with outdoor temperatures reaching 90+F in August, while I keep a 5g and 10g batch at lager and ale fermentation temps respectively in fermzilla conicals. Cooling down takes longer than I thought, and on my first go it felt slow but it might have just been expectations vs reality as this is my first glycol chiller experience. The instructions really are as bad as others reviewed, I think because the controller is so spartan, and it takes some getting used to. Once you get dialed in though, and your beer is down to temp, I don't feel like it runs that often and it's not noticeable in the garage setting. I'm very happy I pulled the trigger and I feel like I can brew whatever I want which is great.
One other note, use a funnel if you can to fill. The reservoir has a small opening only. I was concerned that my unit was leaking until I realized it was just some spillage from filling.

This chiller gets the job done, sort of...First, its a nice looking unit. Totally contained and relatively quiet. Mine was good right out of the box with no leaks like others have posted. Easy to set up but adjusting the temp is a little tricky. Keep the little instruction manual that came with it handy because you will need to refresh on your next batch. I wish it did come with casters instead of legs but the casters are easily available on Amazon. (M8-1.25.) Also. there's no way to heat with this unit. Theres a hack on the internet on how to convert it to heat as well but it's fairly involved and I chose not to do that at this time. As far as some complaints about only displaying in Celsius, I just printed out a conversion chart and attached it to the chiller itself. Not a big deal.
Now, for the performance. That's where this unit lacks. I have a 7gal. stainless steel conical fermenter with an insulating jacket. During fermentation, it kept my wort temperature where it was set very accurately. When it came time to cold crash, i set it for 34 degrees F but I could not get it below 41 or so. I brew in my garage where the ambient temperature was fairly warm so maybe that was it but I would think that this unit would have more cooling power to overcome that! Other than that, this is a decent unit and the price point is a plus compared to others out there.

Love it but . . .
This seems to be the lowest price point for a feature-packed chiller targeting those of us in the "home brewer" category. I've been seriously brewing for 4+ years building up to conical fermenters, temp control systems, 6-keg 4-tap taproom, etc. A glycol chiller was last on my wish list and I was finally to the point where it was time to dump the Igloo cooler and spend the money for one. This unit is a well built, compact, cool looking addition and capable of chilling both fermenters (14 gal and 7 gal SSBrewtech Chronicals) simultaneously. The two built-in temp controllers and pumps work great. The default settings on the chiller tank are probably fine left alone but can be programmed to fit your personal needs.

Notable negatives include a 3-page owner's manual that totally blows. It covers the basics as a "quick set-up" guide and that's about it. The unit has "heat & cool" written on the temp control panels, but there is no mention of any "heating" capability in the anemic owner's manual. Zip! There are no easy to find on-line resources to address such anomalies. Also, the push-button controls are tiny and a bit tricky to use, especially on the rear (chiller tank) control panel. They feel somewhat cheap to the touch and are a bit tricky to push/engage. I read similar complaints by others who have reviewed this unit.

I would give it a 4-star rating due to the push button control issue and the scant documentation in the manual. I took one more star away as my initial unit was flawed. When I unpacked it and started the test run, it worked for 10 minutes before the two temp controller LED screens went blank. Nothing I tried brought them back to life. I reached out to MoreBeer and they didn't have a fix, so they sent a replacement unit pronto. It, so far, is working great.

Bottom line, I am pumped to have a glycol chiller. No more swapping out frozen water jugs during the first week of fermentation. No more worries about diving into the world of lagering brews when the mood arises. No problems cold crashing my beer prior to kegging. This unit is remarkably compact and adds a cool vibe to my taproom/brew house.

Incredible Value
I've been using this for nearly a year now, and completely without issue. Set up was easy, and it has worked flawlessly every time. Considering that it comes with the pumps and controllers already installed, this is a fantastic value for the typical low volume home brewer when compared to other glycol chillers on the market. I initially used with with a couple of Fermzilla fermenters until the Brewtools unitanks became available, and now primarily use it with the Brewtools F40. Cold crashing down to 2c is no issue at all for this chiller. Holding two small fermenters at fermentation temps presents no problems. Haven't tried cold crashing two at once, so won't offer an opinion there. More Beer's write up says it'll cold crash a 1BBL fermenter, so I doubt two five gallon batches would phase it much. Long story short: Highly recommended for home brewers. I truly believe you won't find a better value.
