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.

  • 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.

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

The price is the greatest incentive for this chiller. Also having the pumps and temperature controllers included is a huge savings. I plan on using this unit with SS Brewtech Chronicals, and it is a seamless match.

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 cooling unit has a fan for the condensing coil that is definitely noisier than the typical mini-fridge. IMO, noise level is not suitable for a living space--garage or basement OK.
What kind if warranty is offered, especially for the built-in temperature controllers?
Anthony on Sep 1, 2020
BEST ANSWER: All of our products come with our standard 1 year wear-and-tear / factory defect warranty. We guarantee all parts of all of our products for 1 year of regular use. If you have an issue past then we are always here to help. Cheers!
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 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.
Can this unit present Fahrenheit values?
Jason Amsden on May 3, 2020
BEST ANSWER: It seems that the newer generation of the Ice master 2 (2.1) has different temperature controllers for the pumps, than those on the original version. They don't appear to display in Fahrenheit.
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 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 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: I tested the insulation of my chiller in the summer heat of a garage -- excellent. For maintaining ale fermentation temp, I have set the main temp to zero degrees, and it maintained temp with minimal effort. When I crash batches to drop the yeast, I have dropped the temp to -10 as this will more rapidly chill to the mid-thirties. Once at desired temp, I raise the temp back to zero as it will easily maintain temp. Then after yeast drop, carbonate (I also have the Spike CF-10) When I made a pilsner, I kept the main temp at -5 as the fermentation temps are much lower than an ale along with the need to adjust more times during the fermentation phase. I laagered the pilsner at 34 degrees for two months at the same setting. Think of what your ambient temp is where you're brewing. Mine is in a garage -- hot in summer/cold in winter. This unit is efficient to the point where electrical cost is minimal even where I am. I run the second temp controller through a 1/4 inch copper tubing coiled around a small corny keg in a five gallon cooler at the same time I am fermenting and laagering. No problems whatsoever. You also must be an engineer. Relax, Have a homebrew.
Will this chiller allow me to Lager a brew in my SS Brewtech conical with FTS lid?
Thomas S 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.
Has anyone found an extension for the temperature probe? I only need about 3' more. Thanks!

Worked perfectly for my first brew
This chiller is amazing. I used it recently for a Hoegaarden clone. It was effortless to use. No leaks, no issues, just great beer. The instructions are really disappointing for the price point. The Kegland directions are much better and more detailed. I used the heating circuit which is already part of the chiller; but no instructions are provided to use it. I would have liked it even more if all the settings were available from the front. As configured, you need access to both front and back. All in all a great purchase. MoreBeer delivery was quick and everything arrived intact.

Holding temperature quite well at 1.5 celcius
Bought this chiller to work with my Medium BIAC. Works great for keeping temperature at a constant as well as stepping down temp. It is not too noisy for me, but I do hear some slight rattling from the case that I may address one day. For now I just budge it slightly and no rattling type sound.

As most have mentioned, the temp controllers only read in Celsius. Setup was easy. I did try to use this to cool down my boil to pitching temp, but that is not that way to use this chiller. The reservoir is not large enough to cool my boiling wort down. Will stick to using this chiller for lagering and crashing as well as possibly serving one day.

Would recommend for brewer using a vessel that has is jacketed. I used 1 gallon of glycol.

Great Chiller
Best new addition to the brewery. Keeps great fermentation temperatures and cold crashes perfectly. Keeps two 14 gallon conicals at whatever temperature you want without any problems. Can’t beat the price anywhere else especially with built in pumps. Good design. Definitely recommend.

IceMaster Max2
Once I received the second unit it works very well. The first one I got leaked, the same problem a lot of others have had. I repaired one leak (loose crimp style hose clamp) then found a second leak. I returned first unit at that time.
Second one arrived and works very well. Quiet. Dropped 10 gallons of beer in a Spike CF10 fermenter almost 10 degrees per hour during cold crash. Held temp well without running very often.
MoreBeer customer service was very helpful and polite. Mostly lower rating because of lack of quality control on product and the pain of repairing a new hundreds of $$ equipment then having to drain, pack and ship back.
Would be nice if heating controls were wired and working for the US version. I know there is a hack to make it work. It says Heat & Cool right on the temp controllers. Why not make it work from factory if customers are doing it?

Poor QC
Seems well engineered, seems like quality parts were used.
However, I had to disassemble, tighten the hose connections and reassemble. Basic common sense, make sure the hoses are connected securely. Now that it is not leaking like a sieve, it appears to do the job well.

It leaked out of the Box
The input port on one side leaked. The hose was not clamped properly inside. Had to remove and replace the clamp. Other then the shoddy workmanship. It works great once I repaired it.

Great Chiller
The BrewBuilt Chiller came in on time as told. We let it set for a day before we did anything with it. It was a very easy set up. We had it hooked to our fermenter in just a few minutes after set up. We were now able to cold crash our first beer in the fermenter and that made all the difference in the turn out of our beer. For the price you can't beat this chiller. Best investment for our home brew system.

Nice for homebrew
Using this for the first time with my Femzilla with a cooling coil added. The temperature controllers are capable of controlling heaters, but are not wired for that. With my NorCal garage--cold in winter--I'll have to wire the heater circuit up myself. NOTE: Leak test with water but don't wait to put into service without the glycol solution, as this will make a big ice block internally with just water in it.
