Description

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 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 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 BrewBuckets 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 BrewBuckets 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 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. 

Cold Crashing Capacity
Calculated at 75°F ambient temperature with neoprene insulation. 

  • 2 - 1 BBL (31 Gallon) Tank
  • 3 to 4 - 1/2 BBL (15-20 Gallon) Tanks
  • 4 - 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.

  • Length 1: Barb of 1st bulkhead (IN) to cooling system outlet
  • Length 2: Barb of 2nd bulkhead (OUT) to cooling system inlet

Best price for a chiller I don't need to buy anything else to get running.
I liked that it includes the controllers.
JOHN PETER S on Dec 23, 2020
It is all inclusive with nothing to add such as pumps and PID.
Ray W B on Dec 2, 2020
After a lot of research, this unit provided the most features, the fact that all of the pumps and the controler are included make a big difference when comparing to other brands.
Matt Wisner on Oct 30, 2020
Research leads me to believe that this will best fit my needs at an acceptable price point.

What additional items are needed to control
the temperature on the Grainfather conical?
Steve Gawlinski on Mar 23, 2020
BEST ANSWER: You will need to get a stopper with a thermowell and a airlock hole.
Hi folks. Which temperature sensors are best matched to this unit? Thanks in advance
Stefan Mueller on Nov 14, 2020
BEST ANSWER: It comes with built in temperature sensors for each of the built in pumps. No additional sensors should be needed to use this unit for cooling. It will not, however, control a heating setup as far as I can tell and I had to get a separate ink bird sensor to control my heating pad for keeping up my ale's temperature at night in the garage this winter.
It says in manual that all four temp probes have to be connected or you get error.what if I will use it only for two fermenters?
Jonas Kristensson on Jun 23, 2020
BEST ANSWER: Hi. You can individually turn on/off each temperature controller. This will keep the unused controller from turning on the pump, which will shoot out the coolant if a hose is not connected. If you unplug the temp probe it makes a loud beeping noise that can't be turned off until you plug the probe back in. The solution is to leave the probe plugged in and turn off the controller for the unused probe. I loop back the hose from the Outlet to the Inlet to make a loop for an unused controller. This way if the controller gets turned on and tries to pump coolant, it just gets put back into the reservoir. Not the most elegant solution, especially with unused probes hanging there, but otherwise, the chiller works great.
What size tubing did you use on this unit for flow lines?
Dan Sledzinski on Jun 29, 2021
BEST ANSWER: Howdy. I used 3/8 silicone from more beer. Part# H983B. Fits perfect. I did use small quality zip ties for clamps on the barbs and on the chiller coils.
For SS Brewtech 1BBL Brites - where does one put the temperature sensor? All that's needed is the coil, correct?
Michael Kramer on Oct 29, 2020
BEST ANSWER: Temp sensor goes in the thermowell. Different carboys have different thermowell. For ex, the SS Brew Bucket has a thermowell and it comes with a digital temperature display that fits over the thermowell. The sensor(probe) is deeper in the thermowell and the digital temperature display then encloses the thermowell. If you have a 5 gal plastic bucket or glass carboy then you can get lids for those that have a 15 inch thermowell that can be adapted to the lid and the sensor then is sunk down into the wort through the 15 inch thermowell from the top. This should get you started in the right direction. Good luck
What is the reservoir capacity and what is the glycol-to-water mix?
Diane Baas on Sep 17, 2020
BEST ANSWER: The reservoir has an 8 gallon capacity. The included instructions state "Fill the reservoir with a 20% propylene glycol solution - 4 parts RO/distilled/deionized water to 1 part 99.9% propylene glycol.
How long are the temp sensor cables?
Joe Walker on May 29, 2021
BEST ANSWER: Hi John. They are 80” end to end.
What is the dBA level when it's running all four pumps?
Michael Kramer on Oct 31, 2020
BEST ANSWER: I don't have a decimal meter but the unit sits next to my desk and the pumps are extremely quiet to the point I don't even know they're on. The refrigeration compressor is no louder than a mini refrigerator
Does the controllers have an option to add a heater to them as well so the same controller can heat and cool?
Jonas Kristensson on Jun 26, 2020
BEST ANSWER: Hi Jonas - unfortunately the controllers do not have a second input to control a heating element.

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.

Great value fat a quality chiller.
I was surprised by the quality and features of this chiller. The only drawback is that it only reads temperature in Celsius. Love the temperature control I have now.
Love this chiller with my fermenters.

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
