BrewBuilt® IceMaster Max 4 | Glycol Chiller | 4 Built In Temp Controllers & Pumps | 2600btu | 110V | 8 Gal. Tank Capacity

    Description

    The ultimate control & precision of your fermentation process. Equipped with four built-in temperature controllers and pumps, this advanced chiller enables you to independently regulate the temperature of multiple separate fermentation vessels simultaneously, ensuring optimal conditions for different batches or styles of beer, making it a game-changer for homebrewers.
    • 4 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 4 is designed to cool fermentations in small vessels. It features 4 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 four tanks can be controlled separately with one IceMaster Max 4.

    Compatibility
    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 systems and fermenters.

    • BrewBuilt Jacketed Uni Conical - we recommend one Insulated Tubing Kit for each tank. These kits feature "dry break" quick disconnects that prevent glycol loss and the insulated tubing will increase chilling efficiency and eliminate line sweating from condensation.
    • 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 4 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 4. The cooling coil for standard Ss Chronicals and Brew Buckets are not sold a la carte and must be purchased with a submersible pump, which is not needed for the Max 4. For standard Chronicals and Brew Buckets you might consider the IceMaster 100 for cost savings.
    • 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 4 you will only need 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.

    Capacity
    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.

    Capacity calculated at cold crashing to a target temperature of 38°F while the ambient temperature is 75°F with neoprene insulation (double tank capacity for ale fermentation temperature control):

    2 - 1BBL (31 Gallon) Jacketed Tank
    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 2 lengths of tubing per vessel. All tubing connections should be secured with hose clamps.

        Write your review here. It must be at least 20 charaPUT TEFLON TAPE ON THE DRAIN PLUG!Okay now with that out of the way... this is a nice and versatile unit. It performs well. But get ready to learn Celsius if you're in the US, there's no way to set to F. And I'm not crazy about the built in controllers (holding two buttons simultaneous and then holding two buttons again to confirm, then two buttons again to save? Jesus christ), but the unit design is good in terms of what counts - the cooling, the capacity, and the pretty quiet noise. It's about as loud as an older fridge. I wouldn't mind working next to it if I had to. Sleeping next to it wouldn't be fun though. I've been able to chill 14 gallons down from 70 to 33F in around 1.5 hours holding the chamber at 29F. I could hold the chamber lower but that seems like overkill when mostly this thing is just pumping coolant for 3-4 minutes every hour or so to keep the fermentation stable. As I scale up to having 1bbl size fermenters, and possibly 2-3 of them at a time, I think it will work well even if it might be chugging sometimes. Based on the specs it's right for even a 2-3BBL brewery that doesn't need to cold crash quickly.cters long. Consider whether you would recommend this product and what you like or dislike about it.

        Good .powerful.

        Works well. but manual is missing one important hint.Glycol is not glycol . activated glycol, this stuff with anti corrosives is needed. Both can be food grade. If you use only destilled water mixed with glycol , then you still have an autoprotolyse. Means the water is without ions and can corrode the copper tubes easily. Buy the glycol with the inhibitor..it is the same price..but buy it.

        Good glycol chiller

        I bought this to chill my 1/2bbl Brewtech unitank and 20 gallon brite tank and it does an excellent job. Can cold crash 17 gallons down 35 degrees in about 3 hours and with two more open lines I can’t wait to get more tanks!

        It does what it needs to, but it came with some issues.

        As I’m typing this out I have 2 lagers fermenting at 10C and I just kegged an ipa that i cold crashed at 3C so yes it does do what I need it to do. That being said when I first got it there was a leak because 5 of the 8 disconnects inside were not tightened properly with hose clamps. It was an easy enough fix but another problem is that one of the 4 pumps doesn’t seem to work. Again this isn’t a huge deal for me because I have only 3 fermenters but still when you pay almost a grand on a piece of equipment you want it to work properly!

        Awesome unit

        Awesome and affordable. Pumps inside so no external stuff. Held temp fine. Only drawback was no instructions came with it. Went to YouTube and watched videos. Still not sure capacity of water/glycol. Put 7 gallons it.

        It good, not great

        Real rating is 3.5. It can keep multiple tanks very cool and I live the built in sensors. It has definitely helped me up my lager game for sure. Price is fair. Had issues with some of the senor inputs being very loose needing some glue. It will make an annoying sound unless a sensor is plugged in...even if you "turn it off" I find this annoying because I would like to store the other sensor cables away when I'm not using them. The master glycol temp controller (stc 1000) on the bottom went bad on me twice. Moorebeer was great about replacing..but annoying. The one time is nearly froze the glycol which I'm sure would have damaged the system. I won't be leaving it on while I'm deployed...thats for sure. Works as advertised. Could be made with better parts...little worried about longevity on this unit. But we will see.

        When I received it one of the temperature displays was not working. luckily I'm handy and was able to fix it without too much of a problem. Overall it works great. I wish there was a switch underneath every display to shut them off and on other than that I like the unit and it's a great price compared to other chillers

        Best addition to my brewery in years.

        This is a great unit. It seems to be well built, it runs quietly and is easy to operate with a little practice. What drew me to it over the other models is the integrated pumps. However, unless something has changed since my purchase, the instructions that come with it are inadequate to say the least. I recommend downloading or printing the PDF manual from the More Beer website and reading it thoroughly before playing with your new toy. That being said, these instructions are lacking as well. Neither mention putting the drain plug in before filling the bath, a rather important step, and there are a few other recommendations I would make that you won’t find in the manual. First, before you fill the bath or plug it in, cut four short pieces of silicone or vinyl tubing and connect each pump outlet and inlet together. This will prevent you from blowing glycol all over the floor if one of the pumps accidentally kicks on. Second, change the set temperature set point of all four pumps to at least ten degrees above the highest ambient temp of your brewery when not in use. Again, to prevent the pumps from inadvertently coming on. The third point pertains to the glycol/water ratio. The instructions recommend a 20% glycol solution, but say nothing about the bath temperature. The 20% solution will probably be fine if you’re not going to run your bath temp. below 32 degrees. I did some online research prior to my purchase and learned that most breweries run their bath temps at 27-28 degrees f and recommend the glycol solution freeze point be 20-25 degrees lower. ie, 27f bath set point, 2f-7f glycol solution freeze point. This translates to a 33%-35% glycol ratio. The reason for this is that when the unit is under load, say during a cold crash, the compressor runs constantly and the coils drop well below 0 deg. f which causes them to become encased in ice which lowers efficiency. As a test, I did a trial run with 23 gal. of sanitizing solution. (27 gal. Blichmann fermenter in an insulated box). I started with a 25% glycol ratio with a 27f bath. I dropped the solution to 68f and held it for 24 hours, then cold crashed to 45f and held another 24 hours. After the first 24 hours there was about 1” of ice around the coils and after the 24 hour crash, that had more than doubled. So I warmed the bath to melt the ice, drained off one gallon of the 25% solution and added a gallon of glycol to raise the ratio to about 35%. The next weekend, I brewed and fermented my first batch. There was no icing during the 5 day fermentation. Immediately after the 2.25 hour drop from 68f to 45f, there was .25”-.5” of ice on the coils, but this melted within 8 hours of the temperature leveling off, and there was no further icing during the 5 day cc. The test cold crash from 68 deg. to 45 deg. took 2 hours 50 minutes and the beer took 2 hours 15 minutes, which speaks to the efficiency of the proper glycol ratio. I’ve had the Blichmann conical since they first came out, and bought a More Beer heated & cooled about 7 years ago. Don’t get me wrong, I love my More Beer conical, but it takes a long time to cool. With the addition of the cooling coils to the Blichmann, the Brewbuilt cut my cold crash time by 80%-85%, and, in the hottest summer months, I usually can’t get the More Beer below 48 deg. The glycol chiller held it at 45 deg. no problem. You will need to insulate your fermenter as well as possible or keep it in an insulated container of some sort. If you have the ability to add coils or rods to your fermenter and you have the money, I would highly recommend this chiller, just do your homework first. Bottom line, this is the best addition to my brewery in years.Cheers

        Very nice product, pumps and controllers included so definitely saves some money.

        Aside from very minimal documentation it’s working great!! Took a shower in glycol because all the pumps came on when I first fired it up. Cheers!

        Lack of instructions, but solid product

        So I wanted to move away from the space of the garage fridge in my home in Arizona, so I decided on this unit for the price because it came with the pumps and probes. I modified my two SS Brewbuckets by adding the temp twister cooling coil and using full-size keg insulating jackets to cover them. Coils are connected with quick connects with flow stoppers. I plan to do a 3rd fermenter set up. The 4th line i use to chill water for wort chiller. Same quick connect lines into an old 3/8 in SS wort chiller into a 6-gallon insulated bucket. At the beginning of brew day, I set that up and make it as cold as I can. When it is time to chill, the water can be the mid 30s and use another pump to re-circulate the water to chill beer. The system has had the capacity to manage the heat exchange so I can minimize water waste and stay in the garage while brewing. Is this thing an investment, yes. I think in the long run, it will be worth it in the increased capacity to have 3 fermenters going to decrease the water waste from chilling beer as the footprint is small.

        Happy but instructions lacking a critical detail

        Seems to be cooling well and good value.Caution however. The instructions are very abbreviated and Step 2 is to locate and fill the glycol/water reservoir. It would have been helpful to remind you to put the cap on the glycol drain tube at the back of the unit, and how to attach.After cleaning up a gallon of glycol from my garage floor, I ordered two more gallons and now think I am ok although I am only hoping I put the plug on properly. No instructions for that.

        It does do what it says.

        Very limited instructions. Impossible to find more info on internet even through manufacturer’s website. It does make glycol/water mix cold and it does circulate, so I guess it works... for same cost could have bought Blichman and I kinda got buyer’s remorse.

        Works Great!

        I picked this unit because of the internal temperature controls and integrated pumps. (saves you $240-400 over other similar units) MoreBeers support was great I had a few questions about the unit and even during the Coronavirus lock down when all their people where working from home, they went out of their way to answer my question and finding the answers to my questions.The unit is well built and looks great!Make sure you download the online instructions as the ones in the box aren't that great.

        What is the minimum temperature of the reservoir with 50/50 glycol? Can you set it to -15C and will it get there?

        Which model pump does this unit come standard with? There are 2 options for replacement pumps. A 1300 gph and a 800 gph. The pumps in the unit do not look like either one. But which GPH are they? I am using this Icemaster 4 on four 1 BBL Uni X2 conicals and need to ensure they are the 1300 GPH without disassembling this brand new glycol chiller. Thanks in advance!

        Has anyone had an issue with the chiller going too cold? Mine is filled 100% water and set to 10C but it will keep chilling down to 0.5C. I have to turn it off every 6-12 hours and let it come back to room temperature to avoid it freezing over.

        MoreBeer!

        This is why I run it about 40-50% glycol water only fluctuates temp and has a chance of freezing solid. Never had an issue with glycol mix

        MoreBeer!

        The reservoir temperature is adjustable but sometimes when I set it it does not register and I have to do it again. The chiller’s electronic controllers are pretty finicky in terms of meticulously following the instructions. The chiller does not seem to remember my set temperature when I turn off the unit so make sure your set temperature is still registered. If this does not work make sure the thermostat sensor in the reservoir is covered by the coolant or perhaps there is a problem with your reservoir electronic controller.

        MoreBeer!

        Don’t use 100% water

        MoreBeer!

        check your PID controller. You have one for each line and fermenter and a main PID at the bottom for the coolant. In the menu you will find F1.F2.F3 .F4 and so on. Each sub menu has a special function. Esp. F1 sets the temp. G2 the hysteresis. Means the gap between the reached temp and when again it shuts down or start again . No the important part: the coolant controller works totally independent. Download the manual if you are worried watch the video from kegland Australia how to program it and set the F1 to 10C and return to the main menu with pressing F and powerON buttons .

        MoreBeer!

        Mine only did that when I didnt set the bottom cooling pid correctly. It kept the reservoir at .5 C. Get some glycol and corrosion inhibitor if you want the chilled to last.

        Looking to use this with a cooling jacket that can only handle up to 8psi. Does anyone know the PSI these pumps will operate at?

        MoreBeer!

        Bob I have the same question. Did you try using the jacket and did you have any problems?

        MoreBeer!

        If its a closed loop from the chiller to the jacket and back again there shouldn't be much of any pressure. Perhaps a bit if there is a height difference but should be negligable.
