RAPT Fermentation Chamber 240V

The RAPT Fermentation Chamber is an insulated, temperature controlled cabinet that heats and cools a whole fermenter rather than a jacket or a coil, so the liquid holds one temperature from top to bottom. It runs on 240V across a range of -5°C to 45°C.

Everything is driven from a four button colour TFT panel on the front. It sets and holds a temperature, plots the graph as it goes, and runs a multi step profile you have built in advance, so a batch can step through fermentation and a crash chill without you standing over it. Connect the chamber to wifi and it reports to the RAPT portal, a free hub that logs the data, lets you change settings from anywhere and emails you if something goes off plan. It also talks to RAPT Pill hydrometers and thermometers over Bluetooth. Air temperature is not liquid temperature, so if you want the reading to reflect what the yeast is doing, fit a thermowell. The 60cm duotight thermowell with a 2m probe extension is made for this chamber.

Spunding and CO2 regulation are part of the design rather than an afterthought. To run both, we suggest a duotight inline regulator with integrated gauge (8mm), a duotight BlowTie 2 spunding valve with integrated gauge (8mm), two red ball lock plastic carbonation caps, two duotight 6.35mm to 8mm female reducers, EVABarrier 5mm x 8mm double wall gas line for gas in, a duotight 8mm ball lock disconnect (grey and red, gas) for spunding out, and a duotight 8mm ball lock disconnect (black and yellow, liquid).

It also works as a kegerator

The chamber takes four 19L kegs on the floor with enough headroom for a layer of 9.5L half size kegs above them, which is more keg storage than a conventional kegerator of the same footprint. You drill your own holes through the door to fit taps. In a shed or garage that drops below zero overnight, the heating side stops kegs freezing rather than just failing to cool them.

Temperature control is the difference between a repeatable result and a lucky one, and the chamber is not fussy about what sits inside it: beer, wine, spirit washes, salami, bread dough, yoghurt, kombucha, kimchi, sauerkraut, olives, cheese, sprouting seeds.
