Many home made products can greatly be improved with perfect temperature control. The Rapt Temperature Controlled Fermentation Chamber gives you an efficient means of setting, monitoring and controlling temperature, which is perfect for beer and wine making, salami making, leavening bread, fermenting yogurt, kombucha, germinating seeds, growing sprouts, kimchi, sauerkraut, olives, cheese, making spirit washes, mushroom growing, and more. Accurate temp control is the key to getting reliable and repeatable results.

The control panel comes complete with an integrated color TFT screen, the integrated secondary regulator that can be used to regulate gas into the chamber with our Inline Regulator with an integrated gauge or alternatively this can be switched over to the Gauge integrated BlowTie unit to regulate residual pressure in your fermenter.  The 4 button color display conveniently shows a log of historic temperature graphs, allows you to start, set/stop temperature profiles and gives you access to other critical information for that particular fermentation.

The top of the unit also has room to install an optional item C16 Spunding Valve and or item C11 Mini Regulator, so you can ferment under pressure and not cut any holes in the unit for hoses. See Kee's video below for more on this.

This multi purpose chamber can also be used as a kegerator.  In particularly cold climates where the ambient temp is below zero, this chamber can warm your kegs and prevent them from freezing.  This chamber also has a higher keg storage capacity than a conventional kegerator that takes up the same footprint.  This unit can hold four 5 gallon Ball lock kegs on the floor and has enough headroom that you can also fit another layer of four 2½ gallon ball lock size kegs above this. A provision for keg faucets is not included, so you would have to drill holes in the door if you decided to use this as a tall kegerator.  

What is RAPT?

RAPT is a dedicated Internet of Things (IOT) Hub for fermentation logging and control.  It's a free service whereby any RAPT enabled product can both log and store data to the hub where you can conveniently access this data.  The RAPT hub can also allow you to control your devices remotely giving you control of the device regardless of where you are. 

For more information on the portal, and how to create a free account, click HERE.

The RAPT portal enables you to make complex temperature profiles that involve different temperature settings over time. This means you can start/run a temperature profile that is fully automated, and you can also use the app to monitor and or change a temperature setting remotely. It even interfaces with the RAPT Pill floating hydrometer to give you real time specific gravity readings remotely. Note that the KegLand RAPT Pill hydrometer is currently not available in the USA, but can be ordered for USA delivery through AliExpress. 

The RAPT Chamber is not compatible with the Barron Tilt Bluetooth Hydrometer, although you can of course still use a Tilt with this, it will just not interface with the RAPT portal.

Why buy this over a glycol chiller?

Typically in the past, some customers have needed to resort to glycol chillers to chill fermenters but this represents several issues:

1. Glycol chillers often require a very cold liquid to enter into a fermenter causing an excessively cold part in the fermenter core.

2. Glycol chillers consume significant amounts of power and in most instances more than double what the RAPT chamber would consume.

3. Glycol chillers often result in spilling sticky glycol especially when hoses are connected and disconnected to the fermenter. 

4. Glycol chillers generally require penetrations through the walls/lid of the fermenter making the fermenter less sanitary and requiring more cleaning. 

5. Many glycol chillers and fermenter combinations do not have sufficient power or are not well enough insulated to cool to sub-zero temperatures.  So crash chilling is not possible.  This is a significant compromise to a temperature-controlled solution and also results in less ability to clarify the finished beer.

Review by Justin C on 1/22/2023

Delighted with the purchase; the whole experience has been excellent. First, this is not a small purchase; the person who buys this item is well-entrenched in homebrewing and wants to control one of the most critical steps in producing your beverage. The delivery went smoothly; this large item arrived via a lift gate truck. Be prepared to stay home and supervise the unloading, and inspect the packaging for damage. Set up was easy, and if you are familiar with the Rapt IO, the process is the same as keglands other equipment. There is a learning curve to configuring the temperature control properly. I recommend taking your time and conducting a dry run with a fermenter of water or a batch that is not all that critical. The PID settings will vary based on the volume of liquid being used, just take your time and it is not too complicated. This completely satisfies my desire for data/details and my ability to control fermentation from start to finish. Very pleased.

Q: What is in the bottom of the unit? Is there a compressor and mechanical cooling or is this transistor heat/cool control?

A: It has a compressor

Q: Is there a written warranty for US sales? The manual only references the AU ONLY warranty. Will a service company be dispatched or would I have to ship it back?

A: We offer a one year USA warranty. Depending on the problem, we can often fix issues with an on the phone diagnosis and parts (there are only two circuit boards and they are easily replaced). In case we cannot do this, we pay for return shipping so we can resolve the issue, as well as pay for shipping back to you.

Q: is an extended warranty available for this?

A: Currently there is a one year warranty, and no extended option.

Q: What are the ambient temperature constraints? Does it need to operate in a climate-controlled environment, or could it handle an uninsulated garage that might fall to freezing in winter and rise to 110F in summer?

A: It can easily handle freezing temperatures, and despite our illustration of having it in a garage, 110 F is a bit too much for any home refrigerator if you plan on keeping the interior near freezing. It can take short bursts of say 90 to 100 F, although we not recommend 110 F.
This all depends on how you set it - if you set it for 68 degrees F, it will not have much of a problem at 100-110 F, but if you set it at 34 degrees F, this will be much harder on the unit if the ambient temperature is 110 F.
