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
