Quick Overview

  • The IceMaster Max 2 is designed to cool fermentations in small vessels.
  • 2 built-in submersible pumps with independent digital temperature controllers
  • 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.

Product Overview

Discover superior fermentation control with the IceMaster Max 2, a meticulously engineered cooling solution designed specifically for small-scale brewing endeavors. This compact, yet potent unit boasts dual built-in submersible pumps, each armed with an independent digital temperature controller, ready to work in harmony with any vessel equipped with a glycol jacket or submerged cooling coil/rod.

Each temperature controller is paired with a dedicated temperature probe. These probes can be conveniently inserted into a thermowell in your vessel, or, in the absence of a thermowell, simply affixed to the exterior of your vessel. As the heart of the system, the digital controller consistently monitors the temperature within your tank and directs the submersible pump to maintain your pre-set optimal temperature. This ensures precision cooling and promotes ideal fermentation conditions for up to two tanks operating separately with one IceMaster Max 2.

The Max 2 is an ideal solution for brewers who operate with one or two fermentation vessels. While its counterparts, the IceMaster 100 and IceMaster Max 4, deliver exceptional chilling power, the Max 2 is tailored to cater to the specific needs of the homebrewer, providing ample cooling capacity without any excess. Moreover, as the most cost-effective glycol chiller in our range, the Max 2 strikes a perfect balance between performance and value.

With the added convenience of built-in submersible pumps and controllers, there's no need for additional pump kit purchases. The IceMaster Max 2 embodies a complete, ready-to-operate cooling system, offering ease, efficiency, and precision control in your brewing process. Experience the difference with the IceMaster Max 2.

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
