Product Description

Easily Retrofit your Conical with a Cooling System!  

1) Wrap your conical with the Cooling Jacket(s) 

2) Connect the Jacket to your cold water (or glycol) pump

3) Set your temperature controller

4) Start controlling temperatures like the pros!

Conical Cooling Jacket includes:

 1) Conical Cooling Jacket 

 2) Quick Disconnects

A patented design specifically made for home brewing and wine making.  Designed for use on conical fermenters and other small fermentation vessels.  The flexible Modular Cooling Jacket has over 130 square inches of cooling surface to make sure your fermenter stays nice and cool, and it totally encloses the cooling fluids so a heating element can also be used.   (Dimensions:  27” L x 9” H)

The modular design of the Conical Cooling Jacket allows it to fit conical fermenters with a short sidewall.

There is no risk of contaminating your beer since the Cooling Jackets are wrapped around the outside of the fermenters. 

The Conical Cooling Jacket is small enough to fit a typical one-gallon jug/fermenter.  Many 7, 14, and 27-gallon fermenters have a short sidewall (approximately 9 to 10 inches in height); the Conical Cooling Jacket allows you to retrofit your conical with an affordable cooling system.  Depending on the circumference of your fermenters, simply use one Conical Cooling Jackets, or connect two or three or add an Expansion Link together to control your fermentation temperatures!  

The Conical Cooling Jacket is compatible with water and glycol.  Please note, the cooling jacket was designed to operate at 8 PSI or less.  Pressures in excess of 8 PSI may damage the Cooling Jacket.  In our tests, the March 809-PL-HS and 815-PL pumps worked well, as did the 370 GPH and the 500 GPH submersible pumps we use in our Advanced and Premium Kits.    NOT for use with Diaphragm pumps which can generate pressures over 8PSI (typically around 25 to 45 PSI) and will damage the Cooling Jacket. 

Quick disconnects are included with the Cooling Jacket (1/4" male and female, and 1/2" male and female) for connecting to 1/2" tubing. 

If you would like additional quick disconnects for your system, please see the links to Quick Disconnects.

Note: Fermenter and accessories are not included.

  1. incredible product 5 Star Review

    Posted by on 5th Nov 2021

    I ordered one jacket for my 7 gallon SS Brewtech Chronical fermenter and it was a little slow to chill but managed to hold the contents in the 60s while ambient was in the high 70s, so I ordered a second jacket and now I have gotten temps to be in the mid 50s while ambient was as high as 70. I am confident I could get it colder but I will have to check that when the time for cold crashing comes.

    Another key part of my experience is the support, I received. I have had terrible support experiences with similar products but a few minor problems around the ordering process were swiftly and effectively resolved. Will definitely be ordering more as I expand

  2. Perfect for korny keg 4 Star Review

    Posted by on 13th Jul 2018

    The connections are great and it works great. It is a bit small for my fermenter. I did buy the extender so it fits but the cooling area is a bit small and struggles to keep my temps down around 67 during secondary with water at about 50 and ambient temperature about 72. So either ice water or two jackets will be needed. Especially during primary.

  3. Works well but too small for my fermenter 4 Star Review

    Posted by on 13th Nov 2016

    The reason I'm giving 4 vs 5 stars is the because the product description said a single conical jacket will fit from 6"-9" diameter fermenter. I have a 9" diameter plastic conical. To secure the jacket to my fermenter required me to really pull and stretch the Velcro fastener which I felt made the jacket too tight and would restrict water flow. The instructions also advised not to put jacket on too tight for the same reason. That being the case I had go to my local big box HW store to engineer Velcro extensions for the jacket. Hindsight being 20/20 I should have done the math; the jacket specifies its 27" long, the circumference of a 9" diameter circle is approx 29", 2" longer than jacket. I also have a 25W strip heater under the jacket where the power connection also adds to the circumference requiring even longer jacket. Just a heads up to anyone purchasing to double check your fermenters dimensions against the product spec before ordering.

  4. great product 5 Star Review

    Posted by on 12th Oct 2016

    Unpacked and installed on my Stout 7 gallon conical, hooked it up to my submersible pump, and I was in business . With 34 degree water, it brought the temperature from 65 to 55 in about 2 hours. My only regret is that I didn't buy 2 and chain them together . I will definitely buy another for summer time brewing .

  5. Great Product-But has it's limitation 4 Star Review

    Posted by on 14th Sep 2016

    Purchased two of the conical jackets to wrap my 12.5 gallon Spike Brewing Stainless Conical Fermenter. Wanted to crash the temp for bottling. Hooked them up to a Chugger pump and 10 gallon Rubbermaid water dispenser filled with ice. Was able to go from 71 degrees to 53 degrees over a 48 hour period, with the ambient room temp of around 71 degrees. While my goal was somewhere in the 40's, it was taking too much work and ice to keep it going for days....it did turn out to be the best batch yet though, due to being able to crash the temp and get some additional clarification. I can see where they will be great in keeping the conical dialed in at 68 degree for future fermentation, with very little effort. I'll work on the crashing set-up to see how low I can get it next time around...but all-in-all great tool for the homebrew set-up. Would Purchase Again and will promote to fellow home brewers

  6. This thing works! 5 Star Review

    Posted by on 28th Jun 2016

    I homebrew in my garage and this is fine for most of the year but in the summer it is impossible to brew and ferment a beer properly! I have used the conical jackets several times now with awesome results! I highly recommend this product if you are serious about fermenting beer at the proper temps and for the best beer you can make! I also want to say the customer service is exceptional and you can talk to a real person! Thanks Steve for your help and the extra mile!

  7. Automated fermentation cooling at a DIY price 5 Star Review

    Works great! I used 2 cooling jackets for my 12.5 conical fermenter. Fits perfect.

    The description I have for my setup:

    Submersible pump and a bucket with in and out tubes running through where the condensation collection Trey is normally found above the compressor.

    I used a holesaw to drill the holes and also to thread an extension cord through (I bought a cheap flat one I cut and then wire crimped so it would fit) then linked the jackets with a 1/4" to 1/4" barb with worm clamps.

    Damp towels over to insulate and to cool further via evaporative cooling. Would be cool to have an oversize cloth bag with a cord stench at the top that would fit the conical: could just spray it with water every so often and blow off would come out the top. Might try one of those laundry bags...

    Scrape condensation ice into bucket every so often.

    Temperature controller controls the pump, shuts it off when temperature has been reached.

    Pretty much as fully automated as I could make it.

    My apartment gets up to 95 degrees and it still has been working fine!



  8. Great low cost solution for cooling 4 Star Review

    Posted by on 3rd May 2016

    I am using these to cold crash and then maintain temp in my brite for hard cider. Started with 2 around a 1/2 keg, quickly realized I needed four to cool more quickly and evenly. Seems to be well made, very easy to setup with an ice cooler and a water pump. Would recoomend as a solution where a refridgerator is not appropriate.

  10. Temperature Controlled Conicals at an Affordable Price 5 Star Review

    Posted by on 9th Aug 2015

    Thank you so much for allowing me to test your new Conical Cooling Jacket. It has allowed me to brew all summer in our 90 degree Florida weather. Your new Conical Cooling Jacket fit my 7.5 gallon Stout fermenter perfectly. I expect that it would fit any conical that can be separated from it's stand. Initially I only used one cooling jacket because I wanted to see if one would be enough to cool the 5 gallon batch, which it did without any problems. However in the future, I will use two of the Conical Cooling Jackets, which should minimize the amount of time the submerged pump runs. My initial set up consisted of the submersible pump set into a 10 gallon water cooler with about 7 gallons of water in it. I used water heater wrap to insulate the fermenter. Temperature control was maintained with a digital controller and submerged thermowell. Twice a day I swapped out three frozen quart containers of water. I was able to keep my fermentation temperature at 68 degrees in an 80 degree room environment without any problems using one cooling jacket. When I tried to crash drop the temperature prior to kegging I could only get the temperature down to about 50 degrees, probably due to the heat generated by the submersible pump running for a longer period of time. Had I used two wraps I would have obtained greater cooling efficiency and the pump would have run for shorter periods of time.

    After realizing how great this cooling wrap worked, I decided that I needed something that didn't require me to add ice twice a day. I then adapted my system by taking a 5 gallon stainless boil pot and putting it in my Kezzer (adapted chest freezer) and setting the temperature to 40 degrees. This system worked just as well but again the limiting factor I believe was that the pump heated the water in the pot more than I would have wanted it to. Updating to your Chugger pump would eliminate the heating issue. My future plans are to either use a dedicated freezer with a glycol mix and drop the temperature to below freezing or possibly try an aquarium chiller.

    I highly recommend your Conical Cooling Jackets to any brewer who is looking to be able to maintain accurate fermentation temperature control at an extremely affordable price.
