With this "Do It Yourself" kit you can save thousands of dollars compared to buying an off the shelf fermenter with this same capability.

Cool your fermenter without a refrigerator using solid state peltier chips.  We've machined the aluminum blocks so you can easily make your own DIY peltier cooled fermenter.  A peltier chip is a solid state chip that runs on 12VDC and gets cold on one side and hot on the other.  

By mounting a peltier chip onto our aluminum block and using a common CPU fan to pull heat off of the hot side of the chip, you can provide excellent temperature control.  Each aluminum block can support two peltier chips (CPU Fans and peltier chips are not included). 

One block with two chips will support typical ale fermentations and pull a 7 gal. fermenter down by about 10 to 20 degrees (depending on the quality of your chip, insulation, fans, etc.).  For lagers and cold aging, two blocks with 4 chips will perform twice as well.

Peltier Kit for For Stout Tanks and Kettles Fermenters only (7.3, 10, 12.5 gal size with approx. 11.8" diameter).  Will not work with any other fermenter.  Not compatible with "short" or "wheeled" 7.3 gallon fermenters.
 
 
Includes:
  • (1) Aluminum block for mounting (2) peltier chips and CPU Fans.  4"W x 9.5"L with 8 drilled and tapped holes for two fans, plus 8 small holes with pins to trap the 40x40mm chip (chip not included).  Includes chamfers for tie wraps on top and bottom.  Milled to match shape of fermenter.
  • Does not include power supply, temperature controller, insulation, CPU Fans (Heatsink/Fan Sold Separately), peltier chips.
  • Comes un-assembled (machined aluminum block and 8 pins are separate)
Tip and Tricks For Best Results:
  • Read the white paper mentioned above
  • Be sure the Heat Sink/Fan is tightly mounted on the chip (the screws that are included as part of a Heat Sink/Fan may not work well enough)
  • Use thermally conductive CPU paste between the aluminum block and the fermenter (in addition to using it on both sides of the chip)
  • Insulate the fermenter and exposed areas of the aluminum block
  • Turn the fan over and reattach it to the heat sink, so the air blows AWAY from the fermenter
  • We've been able to achieve 35+ degrees of cooling using 2 blocks with 4 chips (89F to 90F ambient and 51F to 52F in the fermenter) with 6 gallons of wort.  (We can't guarantee the same results for you because of all the variables, but we're quite happy with our results!)
  • One block is probably adequate for a 5-6 gal. batch of ales and two blocks are likely needed for lagers - unless you have a cool space for the fermenter, in which case you may be able to later with only 1 aluminum block.
