Temp Twister 9.5mm (3/8') Stainless Glycol Cooling / Heating Coil Kit

Temp Twister 9.5mm (3/8') Stainless Glycol Cooling / Heating Coil Kit – stainless cooling/heating coil for active fermentation temperature control in FermZilla fermenters.

The Temp Twister is an original FermZilla accessory designed for precise temperature control during fermentation. Used with an insulation jacket, it helps stabilise fermentation temperature and supports clean flavour profiles by reducing the risk of typical fermentation off-notes caused by temperature swings.

For temperature-controlled fermentation you’ll need a cooling/heating medium (e.g. an ice-water bath or a glycol chiller), a thermowell, a fermentation controller (e.g. RAPT Fermentation Controller) and a submersible pump. The controller’s temperature probe sits in the thermowell and switches the pump on when needed, pushing the cooling/heating medium through the Temp Twister coil to bring the beer back to your target temperature.

Installation: the fermenter lid requires two 22 mm holes. You can use a dedicated lid made for the coil, or drill 22 mm holes in a suitable lid/fermenter. The included Duotight fittings secure the coil at the lid openings.
