## Description

BrewJacket Immersion Pro Base Unit Introducing The BrewJacket Immersion Pro, a compact liquid cooler that allows you to create world class ales and lagers without a refrigerator and thermostat setup. This complete fermentation temperature control system brings your fermenting beer down as low as 35 F (20 C) below the ambient temperature in your house and can even use the ambient temperature to heat your wort back up if the temperature drops too low. Utilizing a solid state cooling systems, the Immersion Pro pulls heat out of your beer through the hard anodized transfer rod, through a cooling chip and finally to a heat sink where it is fanned out, no need for compressors, pumps or glycol. The upgraded Immersion Pro can even reverse this process, bringing ambient heat back into wort through the transfer rod to raise the temperature in your beer. This system is also super simply to operate, with only two buttons and displays. The buttons raise and lower the set temperature, while the displays provide a real time readout of both the target temperature and the current temperature in your fermenter. The compact design of the BrewJacket Immersion Pro makes cleaning and storage a breeze. The Immersion's rod easily unscrews, allowing you to place inside your fermenter when sanitizing prior to use. After your beer has completed fermentation, clean the transfer rod with soap and hop water using a kitchen sponge and let rod air dry.

## Customer Reviews

### ⭐⭐⭐⭐⭐ This thing works!!!
*by A***R on May 7, 2019*

When I bought this product I was a little Skeptical, how could this actually work? Well i'm on my second batch of beer, and it's amazing. Still not sure how it works, but it kept the temp. Within a .2° degree temp! I plan on buying another one. It's cheaper then running the air conditioning all day!

### ⭐⭐ Eh, could be good.
*by D***O on June 27, 2019*

Didn’t care too much for the customer support. I regret dropping my money on this. Doesn’t cool very great. No where near the 35 degrees above or below ambient. I was getting 25, max.

### ⭐ The promise does not come close to the actual reality of the product
*by D***L on April 30, 2019*

I have three BrewJacket devices. They all started out great and worked for the first several batches. Eventually all of the devices started to no longer cool as they were supposed to.BrewJacket offers VERY limited technical support. As a (possibly) small/young company they obviously do not understand the importance of technical support. It seems to be treated as an afterthought. Possibly this is because they do not have enough profit margin to support technical support.They have no phone number to talk to a human and will not provide a phone numberEmail technical support typically requires three-day turnaround and can extend to much longer for ongoing issues.Having a human to talk to would speed the process.They are consistently out of replacement parts – another sign of a small firm with (possible) cash problems or supplier issues.Sales are now exclusively from Amazon – eliminating typical (industry) distribution channels may be the reason.Shame on me for wanting the promise to meet the reality.
