The Temp Twister Cooling Coil is the ideal option for maintaining fermentation temperatures in any model FermZilla. Use an IceMaster Glycol Chiller or ice bath with submersible pump to push coolant through the coil when temps get too hot. Designed for the FermZilla but can can be used with virtually any fermenter that has an opening diameter of 4-3/8" or wider. The inlet and outlet are extra long so the coil can be used with every sized FermZilla. In order to cut them to an appropriate length for your application, we recommend this compact pipe cutter.

To install, simply drill two 22 mm (approx. 7/8") holes into the lid of the fermenter and use the included Duotight bulkhead fittings to attach the coil to the lid. The FermZilla will still be pressurizable after installing the Temp Twister, just be careful to drill the holes no wider than needed to fit the Duotight bulkheads.

If you're using the Temp Twister with EVABarrier tubing, we suggest adding 2 x DUO112 to your order to help route your inlet and outlet lines.


  • Coil Diameter - 4.33"
  • Coil Height - 14"
  • Overall Length - 26.75"
  • Tubing Diameter - 3/8" OD
  • Made from 304 Stainless Steel
  • Includes 2 x 9.5 mm Duotight bulkheads

If duotight fittings when used on the Fermzilla still allow for pressurization to 35psi?
Roderick Templen on Feb 18, 2020
BEST ANSWER: I'm pressure fermenting now at about 20psi with an earlier leak test with N2 at 25psi, so things might be bit leakier at 35psi. My experience is that the duotight connections seal just fine against the coil. The place to worry about is the connection to the Femzilla lid, where the O-ring is compressed by the big nut. I used keg lube on the ring and threads and that helped.The remaining leak was around a liter of N2 per hour at 25psi, which I decided was low enough for pressure fermentation.
Will this fit in a 30L Speidel fermenter?
Richard Hogg on Apr 6, 2020
BEST ANSWER: Answering my own question, yes, it fits. Just drill two holes in the lid (about halfway between the center hole and the rim) and install. You'll probably want to cut the inlet & outlet a little shorter.
can you cold crash with this and an ice bath?
Clarence Tenley on Nov 28, 2020
BEST ANSWER: I have it in a 16 gallon stainless conical fermenter and am able to cool the beer to 39 degrees with a cold bath (chest freezer of water) at 34 degrees.
Will this work on a one barrel fermenter and glycol chilling system?
Roger Hillestad on Feb 2, 2021
BEST ANSWER: You could use it for that, if your opening is big enough. The coil is about 4.75” in diameter so it won’t fit in a 4” tri clover opening unless you twist it in like a screw. Not ideal to do that
Will this work with a FermZilla All Rounder Fermenter - 7.9 gal?
Taylor Sandfer on Sep 22, 2020
BEST ANSWER: It worked perfectly with myFermZilla conical fermenter. Basically as long as you have 14 inches of space from the lid to the bottom of the fermenter you should be good from that issue. I had to drill two holes in the "lid" of the fermenter, so as long as you have that capability you should be good to go. I hope this helps!
I'm purchased this twister with the thermowell and pre-drilled lid for my Fremzilla All-Rounder. Haven't used it yet but during assembly:

1) Looks like the thermowell will be very close to, if not crash into, the chilling coil. I'm worried this will cause the system to short cycle. I notice the Kegland video does not show both the coil and thermowell installed at the same time. Have users had issues with this?

2) For my short All-rounder the lid gets pushed pretty far down the twisters straight in/out tubes. They look very splayed to me like the distance between the tubes is too short. Does this still seal at the bulkhead o-ring or did others try to bend the pipes to make them more parallel through the lid?

Thanks - excited to get this up and running!

BEST ANSWER: I cannot address the second question, but in my use of the temp twister on the big mouth bubbler, I had the temp thermowell and coils. I sanitized a rubber stopper and added it to the end of the temp thermowell, so that it didn’t touch the coils directly.

Temp Twister for keeping fermentation temps spot on!!
Love this cooling coil. It fits perfectly in my speidel 30L fermenter. Hooked it up to a pump in an ice chest and a temp controlled outlet. Keeps my beer at whatever temp I need.

Have Tested Setup, Need to Use on 1st Batch of Wort
I have not yet used this equipment on a batch of fermenting wort but I am excited based on how it mates to the Fermzilla fermenter I bought along with the Temp Twister. I will update this review once used on live product.

works great
I have a 5gal bucket of water in a beverage cooler and was able to maintain mid 60s ferment temp of 11gals of beers when the garage was in mid 80s. Fermentor was inside a FermZilla 55 Liter Insulated Jacket at the time.

Must have for Temp Control
I'm using it with the 27L Fermzilla and Duotight Thermowell. Tightening the bulkheads is difficult because the nut sits too far into the underside of the lid. If you can get past that you're golden for fermentation and pressure carbing.

Very efficient cooling coil
It is meant for fermzilla, but it works very well with my 30 litre Speidel plastic fermenter. Cools down very fast pitching temp and also very stable ferm temp from 54° to 64° degrees with 80° room temp.

Added chilling to my Speidel Fermenter
I got a glycol chiller recently, and the cooling jacket was too small to wrap it completely. I shortened the pipes a bit with a pipe cutter and drilled some holes into the Speidel lid to install it. It works perfectly!
Final product, with thermowell.
