The IceMaster Max 2 is designed to cool fermentations in small vessels. It features 2 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 two tanks can be controlled separately with one IceMaster Max 2.
The Max 2 is the perfect unit for brewers with 1 or 2 fermentation vessels. The IceMaster 100 and IceMaster Max 4 are terrific chillers, but for they have far more cooling capacity than the average homebrewer needs. The Max 2 is the most affordable glycol chiller we offer, and thanks to the built-in submersible pumps and controllers, there's no need to purchase additional pump kits to use with your cooling system(s).
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.
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.
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.
Note: The new model includes a sightglass that is connected via two plastic Duotight tees. The tees can be attached onto the push tubes on the front of the unit. The sight glass can be fitted between the two tees and plugs need to be inserted on the outward facing openings.
