Temp Twister Cooling Coil

Temp Twister Cooling Coil

60 day no hassle return policy. Details

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.

If duotight fittings when used on the Fermzilla still allow for pressurization to 35psi?
Roderick Templen on Feb 18, 2020
Will this fit in a 30L Speidel fermenter?
Richard H 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.
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!

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.

Great Cooler
Works great. Using it to knock the temp on my Dunkel from 57 to 50 using a cooler for an ice bath.

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.

Added to my 16 gallon stainless steel conical fermenter and it works great keeping the temp steady in a 90 degree Florida garage

Paired with a glycol unit, this cool is able to drop temps fast and keep them in range.
