The IceMaster 100 is a powerful and efficient glycol system that provides precise temperature control of multiple Fermenters, but allows you to expand your capacity as needed!

  • Temp Control & Cold Crash up to 4 - 5-7 Gallon Jacketed Tanks!
  • Tank Capacity: 30L/8 Gal. Water Capacity
  • Cooling Capacity: 780 Watt/2600btu/0.26 ton
  • Power: 110V (3.6 amps)

The IceMaster 100 is designed to cool fermentations in small vessels. It can be used with any vessel that has a glycol jacket or submersed cooling coil/rod. For each vessel you want to cool you will need to buy one of our BrewBuilt Chilling Pump Kits.  Each tank is able to be separately temperature controlled. Each Glycol Pump Kit includes a submersible pump that is placed in the cool bath of this chiller along with a digital controller. The 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 to your desired set temperature. Up to four tanks can be controlled separately with one IceMaster and four BrewBuilt Chilling Pump Kit (GLY355). 

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 Jacketed Uni Conical - You will need one Glycol Pump Kit for each tank.
  • Coolstix - Coolstix can be added to a wide range of carboys, fermenters, and tanks and the IceMaster works really well in combination. Each Coostix Complete Kit comes with a pump kit and controller.
  • Ss Brewtech Fermenters and Brites with optional FTS Temperature Control Systems - Because FTS systems include a pump and controller you will not need to buy a separate Glycol Pump Kit.  
  • Spike Conical with Optional Cooling Package - Because the optional Spike cooling system includes a pump and controller you will not need to buy a separate Glycol Pump Kit. 
  • Speidel Tanks with Optional Cooling Jackets - You will need one Glycol Pump Kit for each tank.   
  • Grainfather Fermenters - Grainfather fermenters have standard cooling jackets. You will need one Glycol Pump Kit for each fermenter
  • Blichmann Fermenators with Optional Cooling Coil - You will need one Glycol Pump Kit 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 a modest amount of insulation so you would obtain better results using Armaflex or a higher R rated insulation.  If only controlling fermentation temps the capacity would be higher.  Four BrewBuilt Chilling Pump Kits (GLY355) is the maximum that will fit in the IceMaster. We are working on smaller glycol pump kits, where the pumps have smaller footprints, so the IceMaster right now has the capacity to use 5 pumps through the bulkhead fittings. 

Capacity calculated at cold crashing to 38°F at 75°F ambient with neoprene insulation (double for fermentation temperature control): 

2 - 1BBL (31 Gallon) Jacketed Tanks
2 - 1/2BBL (15-20 Gallon) Tanks
3 - 10-14 Gallon Tanks 
4 - 5-7 Gallon Tanks

Set Up
In order to hook up the IceMaster to your fermenter or tank's cooling system, you will need 4 lengths of tubing. All tubing connections should be secured with hose clamps.

  • Length 1: Submersible pump outlet to inner barb of 1st bulkhead
  • Length 2: Outer barb of 1st bulkhead to cooling system inlet
  • Length 3: Cooling system outlet to outer barb of 2nd bulkhead
  • Length 4: Inner barb of 2nd bulkhead to IceMaster resevoir (should drain freely, no connection necessary)


  • Tank Capacity: 30L/8 Gal. Water Capacity
  • Compressor: 3/8 HP
  • Cooling Capacity: 780 Watt/2600btu/0.26 ton
  • Refrigerant: r134a
  • Voltage: 110V (3.6 amps)
  • Dimensions: 410mm x 410mm x 660mm
  • Includes 10 stainless bulkheads with 3/8" OD barbs
  • Wheels included
  • CE Certified

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.

On the Icemaster 100, there appears to be a 8 gal reservoir. What is the proper fill level? Based on the instructions a 20% glycol to 4 parts water is recommended. So is 5 gal the recommended fill? or does there need to be a higher volume? I am trying to determine if 1 gal of Glycol is sufficient to purchase with the unit.

BEST ANSWER: I recently filled this unit for the first time. The manual I have claims 7 gallon capacity, but that didn't cover the coils, so I tried more. To cover the coils, you have to go to just over 8 gallons... but this is right at the point of overflow at the fill inlet. If you fill this high, you'll have spillage any time you move the unit, or when your pumps kick on and agitate the water. Based on this, I intend to keep mine filled to 7.5gal. 7gal stated max sure fine, just slightly less efficient refrigeration since a bit more of the coils exposed. Do 4:1 ratio distilled water to glycol n whatever capacity you fill.
I would use the Icemaster to chill boiled wort down to pitching temp before transferring to the fermenter. My system is 1-bbl, target temp probably 70-75F. I usually do a hop stand, so the drop in temp is approx 100F.

I would probably use the unit to chill my municipal water supply well below ground temp, and use a counterflow chiller or similar, rather than directly cool the wort with glycol (since that would likely overload the thermal capacity of the Icemaster).

Does this sound like a reasonable use of the Icemaster, or do people suggest a different way to cool 30+ gallons of hot wort?
Daniel Cook on Sep 13, 2018
BEST ANSWER: This is a reasonable and good way to set up your glycol chiller for cooling hot wort. You are right that you don't want to cool the hot wort with the glycol directly. A lot of breweries use their glycol to maintain a Cold Liquor Tank and run the cold liquor to chill wort then use the hot water that comes out to start the next batch or for cleaning.
What is the warrant period for the icemaster 100 glycol chiller?
Joe Ormand on Aug 17, 2019
BEST ANSWER: Hi Joe, the warranty period is 1 year, covering against manufacturing defects.
The Unit and exterior bulkhead are designed to accommodate for 5 sets of fermenters. But as a couple of commenters mentioned, there appears to be no way to get these 10 lines and 5 pump cords down to the glycol/pump (well, you might squeeze one set through the corner opening). Before I start drilling holes, is there a simpler answer that I am missing on this issue?
JOHN DUNLOP on Aug 24, 2019
BEST ANSWER: There is no need to drill holes. Just slide the three piece top so that there is an inch space between the second and third pieces of the lid (the space furthest from the SS ribs). The lines and cords can easily fit in that inch spacing. If need be, you can widen the space. I then use 1/2” or 3/4” rubber insulating hose that can be purchased at HomeDepot to fill in any extra space where no lines are plus I put it around the lines.
How often should the water/glycol solution be changed out? Do you keep it in the unit when not in use? How do I know it's time to change it?
Richard Eidle on Jan 5, 2020
BEST ANSWER: I check it monthly but I haven't changed mine since I orginally put it into the chiller 15 months ago...i'm within an inch of original fill its still chilling all three of my half barrel fermenters just like day 1.
Does the chiller come with casters or are they a separate item?
Berry Scott on Nov 7, 2018
BEST ANSWER: Yes. It includes Casters that you have to attach. 4 screws per.
My Icemaster has developed a leak at the drain plug. The leak is quite small. It is between the blue plastic insert and the first brass fitting. Does anyone have a fix for this that does not include boxing it back up and shipping......?
KRSanders on Jun 7, 2019
BEST ANSWER: Hi KRSanders - Please email us at info@moreflavor.com or give us a call to go over any sort of issues regarding the chiller.
Can someone tell me more about the drain port on the IceMaster 100? I'd like to know what type of fitting it is... Trying to determine if I can use this port to gravity-feed & prime an external March pump that feeds my existing glycol manifold rather than buying individual submersible pumps. I'm replacing a DIY glycol system that was set up this way and it'd be the fastest and easiest way for me to get back in action. Thx!
Jason Smith on Nov 15, 2020
BEST ANSWER: You shouldn't have any problem with this. People have had issues with the draining on these and I did as well until I fished the piece of plastic left over from when they drilled the hole for the drain. It's funny that the person at the factory just blasted the hole and left piece on the inside to plug the hole back up.

They also strangely made the fan pull air through the front instead of push out the front. From the factory this forces hot air out the sides and on to whatever you're trying to keep cold. Kind of counterproductive. It isn't too big of a job to take the fan apart and flop the armature over if you're careful - this will fix the design error so it blows the hot air out the front and pulls the cold air in through the back and sides.

More information than you asked for, but I have been meaning to share this information for a year and a half now. Overall, this is a pretty solid appliance.
The instructions recommend an 80/20 water to glycol mixture. However, I plan to use this in my garage, which can reach well below freezing in the winter. Ha anyone been able to use a 50/50 mixture successfully? or had problems with it?
Anthony DeWitt on Aug 29, 2022
BEST ANSWER: 50/50 mix is pretty extreme. That’s gonna be a really thick liquid for your pumps to push. You can always drain your chiller if it’s not being used. A 20% glycol mixtures freezing point is 18 degrees F. If your garage is getting colder than that you could bump it up to 25%. But I would consult with the manufacturer before you void all your warranty coverages

A 50% mixture would be overkill it’s freezing Lou t would be around -30F.
My Icemaster 100 has started reading a crazy-high temperature that is inaccurate. Right now it’s reading 34.7 Celsius when the temperature in the resevoir is actually at -7.8 degrees Celsius. So it’s running continuously and getting colder and colder, even though I have it set to 5 Celsius. Any troubleshooting and parts replacement steps would be great. Help please?
Jeff Carlson on Aug 6, 2023
BEST ANSWER: It sounds like the controller or the thermostat sensor is not working. I had a similar problem with My BrewBuilt pumps/ controller. I am now using a Inkbird and the submersible pump from MoreBeer for each fermenter. Accurate without any problems!
How to troubleshoot electrical issue? I bought this 4 years ago and it has worked great until today when it tripped my 20amp breaker. I tried it on multiple 20A circuits and it trips whenever the compressor comes on. The heat exchanger is clean and there is no dust on the radiator. Any idea what to do?
Keith Koval on Jul 4, 2023
BEST ANSWER: Electrical engineer here. There are two options here -- either the compressor starting current is unusually high or there are other loads on the circuit. Since you tried multiple circuits, it sounds like option 2 is not likely, so we're back to option 1. It's normal for there to be a current spike when you start a motor. What's not normal is for it to trip a breaker. Breakers trip on high current (20A breakers usually trip on >30A depending on duration). Most likely is a short in your motor windings. Talk to BrewBuilt and see if they can fix it. Alternatively, if you're using a GFCI breaker you could have a short to ground somewhere. Either way, talk to BrewBuilt to fix it. Cheers!
What is the size of the reservoir and is there room for a 1/4 hp utility pump (12" x 7" x 7")?
Andres Teene on Jun 22, 2021
BEST ANSWER: The pump it too big. The outside dimensions are about 16x16, the inside dimensions of the tank are about 12.5x12.5, and the cooling coils in there. I have 4 of the small submersible pumps from SSBrewTech and they barely fit. The tank holds about 8 gallons, and the 1/5 hp motor barely keeps up in the south Texas heat during the summer. Will only cool to the low 30's.
I recently got this and I'm trying to figure out the best way to connect this to the Brewbuilt 100 glycol chiller. The tubing size that comes with the Anvil coil is too small to fit on the post on the chiller and tubing I have that fits on the chiller post is too large for the coil. Any suggestions? Thank you.

Beware. I purchased my glycol chiller in may 2021. I've used it for approximately 5 to 6 brews max since purchase. My chiller was off and dormant for last 6 months between brews. I fired it up in preparation 2 days before my scheduled brew day and it won't chill the reservoir colder than a couple degrees below ambient temperature. I was planning on making 10 gallons of lager and the whole day had to be scrapped because I have no way to control my fermentation temps now. This was a very expensive upgrade and difficult to justify to my family on a working dad's budget. The warranty is only for 1 year from purchase but I feel with its limited use for it to break down so soon is unacceptable. I've reached out to morebeer! Via their online help center and have received no response. I don't normally go out of my way to review and bash a product butI feel defeated and out of luck with no help. I wouldn't recommend the risk buying ths product. In the future I'll be purchasing my equipment from another more reputable dealer with better customer service and that stand behind their customers and products, even if it costs me more. Good luck to all, happy brewing.

Maybe a great machine with its updated capacity?
I purchased this unit as it was rated for 4 - 1 bbl fermenters and advertised to be able to cold crash 2bbl. After a year this product was not doing as advertised. I contacted more beer and was told that it was due to my slightly higher than normal ambient temperatures and was told it is what it is more or less.

I was shopping around glycol chillers again today roughly a year and half after contacted support, I noticed the product information has changed and the chilling specs have been reduced by half.

If this was the case i would have never ordered this product as it doesn't meet my needs. This is terrible business as I was being told it was my fault for ambient temps but obviously something has acurred that they had to respect the machine....

Thank you for the help morebeer.

Chills great. A few annoyanes. Instructions lacking.
The chiller is able to cool 8 gallons of glycol/water mixture to below freezing and keep it there, even in a garage at 75F. I haven't been able to hook it up to the fermenter yet to test. But it appears to do exactly what it is supposed to do. The default settings are reasonable and make it easy to get started.

The reservoir is too small to hold more than about 3 of the larger pumps that MoreBeer sells, so it isn't clear how to take advantage of all of the 5 in/out ports.

Once you route all of the internal hoses, it is difficult to impossible to remove the inner cover for the reservoir. Hopefully that will be a rare event.

The compressor is fairly quiet, but I am glad that it is in the garage instead of in the house. It would get irritating if I could hear it in my main living space.

The unit was packed in thin styrofoam that was busted to pieces when the package arrived. However, the unit appears to be undamaged and functioning properly.

The instructions are a bit lacking. It would be nice if there were a diagram of the unit that labeled the parts, etc. And a little more detail on steps like "install the drain plug" - like, where is the drain, what is the plug, how do you install it - would be helpful.

Overall a solid product, and I would buy it again, especially at this price point. But there is room for improvement in a few areas as listed above.

Works awesome!
No issues out of the box, easy to set up and get running. I'm only using it on (1) 7 gal fermenter, but I have no doubt it would tackle multiple without issue. Works great. Also super handy to help speed up getting the wort to pitching temp if its too hot out of the kettle.

Works Great, but...
I have no problem with the operation of this unit and it works like a charm and is what I envisioned when I purchased it.

The main problem that I had was with the set-up of the unit. I understand that equipment would vary between different types of units to chill, but I struggled with setting the unit up correctly. I think that you should offer an attachments kit with all of the hoses and clamps needed to connect the pumps to the bulkheads.

I feel the the inner cover could use a little bit more re-engineering, as it would be nice to have it close the whole system and just have holes for the hoses to enter and exit the unit. You could have plugs fill the other unused holes to keep the system as closed as possible.

I really do LOVE this chiller, and it is worth every bit of the money spent and hassle of setup. Thanks.

Works well. Some noise with it, but that is to be expected for what it is. Paired with a pump and temp monitoring (I use a custom setup using BruControl PC software), it holds temps very well. Definitely will make my brewing more precise than a fridge.

Great product
Purchased in early 2020, have kept in my basement and use for my 4-tap system on my first floor. As quiet as my chest freezer and as reliable. It's been running for a year straight so far without issue. It worked right out of the box with minimal setup. I bought penguin pumps and lines for this. This chiller seems tough to beat for the price.

So far so good.
So far so good. For the cost savings versus the Ss brewtech 3/8 HP chiller this is worth it. I have done one brew so far and it has worked perfectly. I would caution people to purchase their own shark bite style drain plug in place of the drain plug provided since this one can be a little touchy and leak.

I love this thing!
I bought my Icemaster in mid 2019 after forgetting to recharge an ice bath and losing a 10 gal batch of beer.

A reliable chiller allows an entire fermentation to be done with precise temperature control and no user intervention, so you can brew with little concern for your upcoming schedule. The unit can also quickly crash chill the wort when fermentation is done.

I initially chose the Icemaster because of its attractive price relative to its cooling capacity.

The quality of my unit was excellent as delivered. is very quiet and has been trouble free.
