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
  • 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

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?
Anthony on Sep 1, 2020

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.
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.
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.
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.
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.
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.

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.

Exceeded my expections
This all in one unit has so far exceeded my exceptions. seems to be well constructed and temps are very accurate. Set up is easy.Just one area of improvement would be to add some care & maintenance instructions to the documentation. There is nothing about this.

Great chiller
The chiller works well for our homebrew operation. Conditioning lagers in the G4 is taking less time and producing great beer.
Chiller with 14gal Blichmann G4 Fermenator.
Easy setup and great performance and flexibility.

Works pretty well
Very easy to set up. No leaks. Pretty quiet but you definitely know when it is cooling down. My only complaint is that is reads in Celsius.

Great investment!
Picked this up at the border. No problems bringing it across. Used it to cold crash two fermenters with a pseudo-lager. So much simpler than switching out ice packs! Highly recommend!

Tighten down the sight glass before filling
Fought leaks and ended up having to disassemble it to correctly assemble the “sight glass” fittings. Once that was done it’s been smooth sailing.

Solid two vessel chiller
Picked this up to work with my two Spike CF10 fermenters. After resolving an 'issue' that was caused by the gallon jugs of distilled water coming over-filled, it's been without issue. I did, initially, attempt to use the MB butterfly hose clamps, but those leaked so I replaced them with oetiker clamps (zero leaks, ever).

The room this sits in (same as the fermenters) is in the 78-85F range depending on the weather and other factors. Such as what the fermenter temperature needs to be at (if the chiller needs to run more, the room gets a little warmer). I've had one of the fermenters at 38F since Saturday with the batch carbonating. That fermenter will be drained before the coming weekend is over (CO2 is already disconnected from the carbonating stone). Second fermenter is going at 70F, also since last Saturday.

I removed one star due to a couple of shortcomings of the unit.
1. No wheels or wheels option. I had to order a set from Amazon (luckily someone has posted the thread size, but it's metric) and install them before I started using the chiller. Wheels, for me, is critical since I'm space constrained and need to be able to move it without hurting my back.
2. All temperatures are ONLY shown in C. With being sold in the US, it should at least allow you to select what scale you want to work with. I don't think in degrees C but degrees F. Which means I have to use a conversion app (on my phone) to get the setting I want. I know I'm not the only person that wishes this had the option for degrees F.

Noise level is of zero issue for me since this lives in the basement room, which also has a chest freezer and dehumidifier running. So there's already noise down there. It might be an issue IF I had in a different part of the house, where I was hearing it constantly. But that's not the case.

I didn't go with the listed recommendation of using silicone tubing to 'loop' the connections when you don't have a fermenter connected to it. I simply have a piece of stainless tubing bridge the ends of the lines that normally feed the chill coil (from Spike) to make those closed loops. I do turn off either side if not in use, to prevent the unit from sending glycol through.

I've also used a stronger concentration of glycol than 20%. I'm somewhere around 30-35% now due to needing to go below -8C to get a batch to my target temp (35F) to carbonate. I've since shifted to carbonating at 38F for the summer. Come the fall through end of spring, I'll probably go back to the lower temperature to carbonate (to use less CO2).

Great glycol chiller
I needed a chiller for my 2 SS brew buckets and this fit the bill. Good price and included the pumps. Connected the tubes and no leaks! I purchased the thumb screws that were listed on the "you may want to purchase these with this". Started the rig cooling its glycol solution while boil was going and was cooled to -1 C by time I got the wort into my brew bucket. I did put insulation around the in/out lines going to my jacket around my brew bucket, no condensation issue so far.
