Brew Monk Spiral Cooler for 30L Stainless Fermenter - Immersion Cooling Coil with Lid
The Brew Monk spiral cooler turns the 30L Brew Monk stainless fermenter into a temperature-controlled fermentation vessel: a stainless steel immersion coil that drops through the fitted lid disc and puts cooling water in direct contact with the beer’s core. Connect tap water or a glycol chiller, and fermentation heat has nowhere to hide — hold ale temperatures through the most violent krausen, run proper lager temperatures, and cold-crash before packaging without moving the vessel.
The set includes the stainless cooling spiral with threaded bulkhead fittings, the machined lid disc, and sealing O-rings — assembled in minutes, cleaned like any stainless part. Pair it with a temperature controller and a floating hydrometer and the fermenter becomes a set-and-forget system: the coil handles the heat, the controller handles the decisions. Fits the Brew Monk 30L stainless fermenter (art. 017.071.2 series).
