The IceMaster Max 2 is designed to cool fermentations in small vessels or barrels. It can be used with any vessel/fermenter/tank/barrel that has a glycol jacket or submersed cooling snake/coil/rod. This chiller features 2 built-in submersible pumps with independent digital temperature controllers, allowing you to control the temperature of 2 separate fermentation or storage vessels at once. Each digital controller includes a thermal probe that should be inserted into a thermal well in your vessel or can be taped to the outside of the vessel if you don't have a thermal well. The digital controller then measures the temperature of your tank and turns the submersible pump on or off to cool the liquid in your vessel to the desired set temperature. 

The Max 2 can be used with any fermenter that has a built-in cooling jacket or a submersed cooling coil. It works well as the cooling source for the following:

  • Speidel - Speidel tanks with optional cooling jackets.   
  • Barrels - If you use our barrel snake. This can be particularly attractive for a white wine ferment in a barrel.

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, how the tank is insulated, and what the ambient temperature is. Cold stabilizing always requires the most energy and requires well insulated tanks. We are currently experimenting with capacities but can provide this rough guide to get you started.  

1 - 40 Gallon Tank or Barrel
2 - 10-20 Gallon Tanks

Set Up
In order to hook up the IceMaster to your fermenter or tank's cooling system, you will need 2 lengths of tubing. 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: 600 Watt/2000btu
  • Refrigerant: r134a
  • Voltage: 110V
  • Dimensions: 19" x 12" x 17.5"
  • Wheels not included

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.

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: Users on HBT were comparing the noise level of various chillers - the Icemaster 100 registered around 55dB at 3ft. It sounds like this unit uses the same internals based on the manufacturer website/video, but it could be marginally louder since it has a smaller enclosure.
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 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.
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.
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.
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.
What kind if warranty is offered, especially for the built-in temperature controllers?
Anthony on Sep 1, 2020
Since the unit I received is different than what’s shown is the refrigerant stated above the same used in the new style?

A few kinks but a good product
Got this chiller to keep my wine cool post fermentation. After some confusion and help from Morewine support, I got it working and now keeps my 60 liter Speidel container at the temperature I want. I paired it with a cool stick and a cooling jacket.

I'll say right off its a very good glycol chiller and I recommend it. took about an hour to get the 4 gallon bath from 75deg f down to 30f. Its now running a real 5gal fermentation. used it to cool wort from 84 down to 70 because the water temp here is warm right now. worked perfectly. pitched and have the fermentation at 19c. The unit kicks on to keep the bath cool 2x an hour and only runs 2-4minutes per. The pump only comes on 1-2x an hour and runs 2minutes. might increase a little when fermentation picks up. when the compressor is running its about as loud as a microwave. not loud & can't hear it outside the room. the pumps, can barely tell they are on from 6ft away. 4star- because the controllers only read in C. the instructions were not with the unit. really hard to set up without them. They can be found online ( keg land G20.1 )

First Use of IceMaster Max 2
I wholeheartedly recommend this chiller.

After receiving my chiller, I filled and tested the unit. Pleasantly surprised at how well it retained temperature after reaching 0 C and then turning off (warm garage) as it had less than a 3 degree rise after 12 hours.

The ease of operation and the ability to quickly "dial in" temperatures at the drop of a hat is an incredible option for home brewing. The internal pumps eliminate the purchase of multiple pumps and temperature probes as with most other glycol chillers. Less mess and hassle as i see it.

I have started my first fermentation with it in a Spike Conical, initially at 18 C for the initial fermentation, raising it to 22 C and then back to 19 C during what is now the dry hopping and letting the yeast clean up. Next will be cold-crashing to low thirties and eventual forced carbonation. Last brewing cycle used many, many bags of ice with constant tending. This unit makes all that vanish.

Awesome Chiller
Very nice chiller. Using it for one 7 gallon uni tank currently and works awesome!!! However they need to put the instructions for the temp controllers with the unit... After much research I found out this is actually a Kegland G20 unit with BrewBuilts name on it. So download the G20 manual and you are good to go!!!

Not as Advertised
I think I have figured out the chiller but the model being advertised and the instruction manual on this website are not the same as the one shipped to me.

Response from MoreFlavor
Hi Joseph, thank you for writing a review! You must've received one of the newest versions of the chiller. We've just uploaded the updated copy of the instructions to the Documents section listed under the product description. Cheers!

Preliminary Review Only
I want to really like this and in time I believe I will. 3 STARs based off the following, will be adjusted once issues resolved. 1) What was advertised and what were sent are 2 different versions. No instructions came with the chiller and the ones online are for the previous version. 2) Leak between the internal bulkhead and the barb fitting. Talked to Customer Service (very nice person I talked too) was unfamiliar with this new version but said will escalate to a technician for review. In the mean time they ask me to unscrew the lid and see if I could self-repair. Unfortunately the tubing and barbs were under the electrical wiring for the PID controls and connected with crimp fitting. Without taking a good portion of the chiller apart it was not a doable fix. Waiting to hear back for Service on a swap or return of the current chiller.
Leak when pumps running.  Bad connection/crimp that is not easily accessed
Front of Chiller.  Not what was advertised.
