KL15813 RAPT Fermentation Chamber | User Guide
The RAPT Fermentation Chamber is quite simply the best, easiest and most powerful fully inclusive fermentation chamber on the market.
Featuring built in heating and cooling, full integration with the RAPT ecosystem, Bluetooth functionality for powerful integration with the RAPT Pill Hydrometer range, this unit will allow for completely remote yet exceptionally powerful fermentation control.
With the RAPT Digital Regulator & Spunding Valve, you will can pressure ferment remotely - imagine being able to pitch your yeast and not touch your fermenter again until it is full of cold, perfectly carbonated beer!
Featuring an integrated TFT screen and custom integration for Spunding and Inline Regulation.
RAPT Fermentation Chambers are designed to have tight integration via Bluetooth with the RAPT Pill Hydrometer & Thermometers.
Bluetooth Guide | RAPT Fermentation Chamber
Bonding a RAPT Pill to send telemetry is a powerful and robust way to really leverage the versatility of the RAPT ecosystem.
Please refer to this video for a detailed guide to Bonding your RAPT Pill to your RAPT Fermentation Chamber or Temperature Controller.
Once the Pill has been Bonded to the device, it can be selected in the Settings menu as one of the available Temperature Sensors. Once selected in this menu, temperature control will be ceded to the selected Bluetooth enabled RAPT device, rather than the internal temperature probe. In addition, on the TFT display the current (most recent) Graity and Temperature reading will be displayed. The internal (built in probe) temperature is also displayed. NOTE: this is not displayed in Graph Enabled Mode.
Once the Pill has been Bonded and selected as the Temperature Sensor of the device, powerful Profile features are unlocked.
You can set triggers such as Gravity or Gravity Velocity, as well as Time for your fermentation control.
For example, instead of setting a fairly arbitrary length of time before you start ramping the temperature of your fermentation for a diacetyl rest, you can choose a specific gravity point or (even mrore acurately) a specific Gravity Velocity (rate of change of gravity) as a trigger point for increasing the temperature.
A common Fermentation Profile involves maintaining temperature for three days, and then increasing the temperature as the Gravity Velocity slows down, and then again when the Gravity Velocity slows further, signalling that fermentation is nearly done. This type of profile can work (with slight variations) for nearly every yeast, and allows us to maintain optimum yeast health and activity for a fast but clean fermentation!
This can be downloaded to your RAPT account and can then be adjusted to suit if required. It illustatres how easy it is to have an automatic profile that suits almost every ale fermentation, and can easily be tweaked to suit lagers.
For more information about this and other features please watch this video.
NOTE: It is completely normal for there to be a temperature variance between the internal probe and the Bluetooth enabled RAPT device. This is because the Bluetooth device is measuring the temperature of the fermentation (typically), and the internal probe is measuring the air temperature of the RAPT Fermentation Chamber. This difference will be greater when the RAPT Fermentation Chamber is actively heating or cooling.
The Allowed Sensor Diff. Iin the menu) sets the allowed temperature differential between the desired setpoint and the current temperature of the Fermentation Chamber. Cooling and Heating is disabled temporarily if this differential is exceeded. The default differential setting is 5°C. This value is suitable for typical use.
This differential can be altered in the Settings menu. If the temperature differential is exceeded, the RAPT Fermentation Chamber will suspend heating and cooling until the differential is reduced. The legend DIFF OVERRIDE will also be displayed when the display is in Graph Disabled Mode.
The RAPT Fermentation Chamber will suspend active cooling or heating and resume as needed – no intervention is required. Once the differential is reduced then heating and cooling will continue as normal.
The Allowed Sensor Differential can be a powerful tool for temperature control. The default setting of 5°C is perfect for most use cases. However, you may choose to increase the differential to allow for more sustained and thus faster heating or cooling, for example. The Sensor Differential can be reduced as well - meaning that the a, which can be useful if there are large temperature swings during fermentation.llowed temperature swings in the chamber will be reduced.
Note that in most cases 5°C is appropriate, and too great a differential can causes issues such as freezing.
Change the Screen Board | RAPT Fermentation Chamber
Swapping the KL17091 TFT RAPT - Fermentation Chamber - Screen Board is quite a simple process.
Please refer to the following instructions should you need to swap the Screen Board for any reason.
WARNING: Ensure the RAPT Fermentation Chamber is unplugged before proceeding

Finally, simply reassemble the unit following the same steps in reverse order.
How to fix a RAPT device that is boot looping | Recovery Mode Guide
If your RAPT device boots up but continually ‘loops’ back to the start up logo, this indicates that the device is stuck in a ‘boot loop’
This can happen for several reasons including but not limited to a failed firmware download, power interruption during install, poor network strength.
A Boot Loop can occur on any RAPT device with a screen – including but not limited to RAPT Fermentation Chambers, RAPT Temperature Controllers, Gen 4 RAPT BrewZillas.
A Boot Loop issue is quite easily rectified.
Generally, a Boot Loop can be resolved by resetting NVS.
An NVS reset is performed using the following steps.
You may require assistance, as you need to unplug the device and re-plug it while accessing the control panel.
STEP 1: : Unplug the RAPT device that is boot-looping.
STEP 2: Hold down the Up or Down buttons on the RAPT device
STEP 3: While holding the buttons down, plug the RAPT device back in. Keep the two buttons held down while the unit boots up.
Note: it is quite helpful to have another person assist with this.
STEP 4: The device will reboot, and also clear NVS. This will reset the unit (so it will forget the current WiFi config and Registration settings unfortunately) but it will also restore it to the last stable firmware condition.
STEP 5: Once rebooted, you can go through the initial steps required to connect the device to your WiFi network. (See the appropraite Get Started! guide for step by step instructions if required)
STEP 6: One connected to WiFi, please navigate to Check for OTA Update in the Settings menu and select this. This will download and install the current firmware.
Please ensure you have a decent, stable WiFi signal before updating, as dropouts during this can cause 'boot loop' issues as experienced.
STEP 7: This operation may need to be performed a couple of times to be successful. A successful NVS reset will display a Connect this device to the Internet message after booting up. If this does not appear please perform the reset operation again.
In the unlikely event that an NVS reset does not fix a boot loop issue, we can perform a full reset into recovery mode. This will reset the device back to factory defaults, and restore it to the last verified firmware.
Recovery mode operates as a bootloader which gives access to settings independant of firmware. This can be useful in some situations such as experiencing issues with your RAPT device due to a corrupt firmware or a problem with a firmware update.
Typically the avergae user will not need to enter Recovery Mode.
STEP 1: Enter Recovery Mode
Unplug the RAPT device, then plug it back in while holding all 4 main buttons down - Up or Down Select Cycle/Back
Once it boots up, you will see a screen called Recovery Mode Main Menu
STEP 2: Select option [0] Rollback last OTA update and reset.
Use the Up or Down buttons to select the required option [0] then select Cycle/Back to do this.
If successful, the message Rollback to previous firmware worked will be displayed, and the RAPT device will reboot. You may then need to reconnect the RAPT device to your WiFi network and perform an OTA firmware update, then re-register the device to your RAPT account.
STEP 3: If unsuccessful, the message Rollback is not possible will be displayed, and the unit will stay in Recovery Mode.
You will need to manually connect the RAPT device to WiFi and update the firmware manually while in Recovery Mode.
As there is no on screen keyboard, the easiest way to do this is to setup a HotSpot on your phone with a super simple network name and password – such as all capital 'A's for the name and password.
Thus create a HotSpot network name of AA and a password of AAAAAAAA.
Use the Up or Down buttons to select option [1] Connect To Wifi.
Follow the onscreen instructions to enter the SSID and Password on the controller.
Otherwise use the navigation keys to enter your home WiFi Network SSID and Password manually
Once connected to the network, the RAPT device will go back to the main Recovery Mode menu. This time, select option [2] Do OTA Update
This will update the RAPT device firmware. Once this is down, please unplug the RAPT device then plug it back in after 30 seconds. It will now start up properly.
If you used a custom mobile phone hotspot to connect you will now need to connect the RAPT device to your home WiFi network. Please refer to the online user manual for step by step instructions. The RAPT device will also need to be re-registered to your RAPT account after this.
In the unlikely event that resetting NVS and entering Recovery Mode does not fix a boot loop issue, please contact KegLand at or your local retailer for warranty support.
Profile User Guide | RAPT Fermentation Chamber
Profiles are a key component of the RAPT system. Profiles are powerful tools that can be customised to a great degree, allowing extremely fine control over all aspects of brewing/fermentation
Profiles are created in the. There are also Global Profiles that can be imported and customised. Once a profile is created in the RAPT Portal, it can be sent to the corresponding RAPT device using Send Profile To Device from the My Profiles screen. Alternatively, you can select Start Profile Session for the RAPT Fermentation Chamber in the Dashboard. This will send the Profile to the device and also begin the Profile automatically.
The RAPT ecosystem is intended to be largely controlled remotely, and thus there are more powerful controls in the RAPT Portal than on board the RAPT Fermentation Chamber.
Once you have registered your RAPT Fermentation Chamber on the RAPT Portal you can then log telemetry from the device and set up complex temperature/fermentation profiles involving multiple steps.
To setup a fermentation profile on the RAPT Portal select My Profiles and then Create New Profile. Then add your fermentation profile steps such as primary fermentation, diacetyl rest, dry hop, cold crash etc.
Operating the RAPT Fermentation Chamber
The Digital Controller has 4 buttons which serve different functions depending on context
Cycle/Back - navigation between On Screen options. Exit without saving. Hold when prompted to advance Profile steps
Select - Select the current option. Enter a Selection. Confirm a choice

This gives the option to Start Profile Now, Start Profile Later, View Profile or Delete Profile.
Note: Delete Profile deletes the Profile from the device only. It does not delete the Profile from the RAPT Portal.
Selecting Start Profile Now will automatically download any updates or changes that have been made to the selected Profile in the RAPT Portal and then begin running the Profile on the device.
Selecting Start Profile Later will automatically download any updates or changes that have been made to the selected Profile in the RAPT Portal. You will then be taken to the Delayed Start screen where the desired Start Time for the Profile can be selected.
Once entered, the Profile will begin automatically at the selected Start Time.
Selecting View Profile will show the Profile Steps before the Profile is started.
Alternatively, you can select Start Profile Session for the RAPT Fermentation Chamber in the Dashboard of the RAPT Portal. This will send the Profile to the device and also begin the Profile automatically.
When a Profile is running on the device, each step of the Profile can be viewed in the Profiles menu of the device.
The Profile can be controlled directly. You can Pause or Stop the currently active Profile.
Using the Up or Down buttons, you can navigate to each step in the currently active Profile.
Selecting a Profile step will commence that step unless it is already active.
Selecting a Profile step may also show other opptions depending on the nature of the Profile step. For example, selecting a Profile step with a duration timer will bring up a slider that allows you to choose the point at which to begin the step. These options are dependant on the type of Profile step being selected.
To stop running or to pause the Fermentation Profile on the device press Select to enter the Profile Menu.
In the Profile Menu use the Up or Down buttons to navigate to and Select either Pause this profile or End this profile.
Pause this profile will stop the current profile until it is started again in the Profile menu
Stop this profile will stop the profile
If you decide you don’t want to register your RAPT Fermentation Chamber to the RAPT portal and hence not use the Wi-Fi functionality of the controller you will in turn lose a lot of the functionality of the controller which is offered through the RAPT Portal. This includes features such as setting up complex temperature profiles which are run automatically and logging past temperature profiles.
At the home screen press the Up or Down buttons to adjust the target temperature. The Fermentation Chamber will then automatically send power to the heating or cooling terminals to power on your heating or cooling device to maintain this target temperature.
NOTE: This is possible only if the device is not currently running an assigned profile.
The Wi-Fi connectivity of the RAPT Fermentation Chamber allows you to monitor, track and start a complex temperature profile involving multiple steps remotely through the RAPT Portal. In order to fully utilise the capabilities of this device you should connect your RAPT Fermentation Chamber to your Wi-Fi network and register it to your account on the RAPT portal at https://app.rapt.io
This will allow you to track and monitor your fermentation in real time remotely without needing to walk over to your Fermentation Chamber. It also allows you to setup and send complex fermentation profiles involving multiple steps to your RAPT Fermentation Chamber which will then automatically run through this profile and adjust the set temperature as required.
In order to have access to this Wi-Fi functionality you will need to sign up for a RAPT Account, connect your RAPT Fermentation Chamber to your Wi-Fi network and register your device on your account on the RAPT Portal by following the setup instructions
Other Settings that can be adjusted directly in the RAPT Portal include Heating and Cooling On or Off, Heating and Cooling Hysteresis, Fan and Light operations/modes, Compressor and Mode Switch Delay and Telemetry Frequency.
To access these Settings in the RAPT Portal select the Edit button for your RAPT Fermentation Chamber in the RAPT Portal.
The temperature set point can also be set through the RAPT Portal or a profile session can be started from the RAPT Portal which will automatically begin the profile you have created.
To change the temperature set point in the RAPT Portal simply enter the desired Set Point target and press Set
Once you have registered your RAPT Fermentation Chamber on the RAPT Portal you can then log telemetry from the device and set up complex temperature/fermentation profiles involving multiple steps.
To setup a fermentation profile on the RAPT Portal select My Profiles and then Create New Profile. Then add your fermentation profile steps such as primary fermentation, diacetyl rest, dry hop, cold crash etc.

If the above do not work, see Using Phone as Hotspot below
If the above do not work, see below
Cannot update firmware | 28674 Error
This is a network issue. The OTA Firmware Update could not be validated or was incomplete. Ensure your device is as close as possible to the router. Check signal strength in Diagnostics
Error 28674 is an error opening an HTTP connection. Check your modem or router settings. A VPN, Firewall or other setting may be blocking outgoing connections - this is a common reason for this error
Ensure you have a strong 2.4gHz WiFi signal (not just 5gHZ). Check your signal strength against
If issues persist, reboot the device and also the modem
If the above do not work, see below
If updating the firmware persistently fails or throws an error, and all troubleshooting steps have failed, then try using your mobile phone as a Hotspot to resolve this.
Using the phone as a Hotspot will typically solve firmware update issues of this kind
1: It helps eliminate potential network or modem/router issues which can cause problems that can be hard to isolate and resolve
2: It can help eliminate signal strength or poor WiFi connection issues as the phone can be positioned right next to the RAPT device when in Hotspot mode.
To connect to the phone Hotspot and update the firmware there are a few steps to follow
On the phone, turn WiFi OFF. When troubleshooting firmware download or network issues, we do not want to use the same network thus the phone must be disconnected from the WiFi network in order to do this
Enable Personal Hotspot (sometimes just called Hotspot) on your phone. This is typically located under the WiFi or Network menu in the Settings menu of the phone. On IOS this is under Settings/Personal Hotspot. The menu names will vary on Android depending on device
Enable Maximise Compatibility (on IOS) or 2.4gHz Network Only (on Android - again, this will have different names depending on device/OS). This will help minimise issues when connecting
Once Hotspot is enabled on the device, following the steps in to connect to the phone Hotspot
Once connected, navigate to Settings/Check for OTA update on the RAPT Device
Cannot open Captive Portal
Check that WiFi is active on your mobile device

If you intend to pressure ferment in the RAPT Fermentation Chamber you may find it useful to install a KL15042 duotight BlowTie Spunding Valve and/or a KL15035 duotight Inline Regulator.
The duotight BlowTie Spunding Valve will allow excess pressure built up during fermentation to be released from the fermenter allowing an optimal fermentation pressure to be set based on your beer style and recipe.
Installation of a duotight inline regulator allows for easy pressurisation for closed transfers for example.
There is a mounting point on either side of the RAPT Fermentation Chamber for mounting a duotight BlowTie Spunding Valve or Inline Regulator.
Remove the cover panel behind the RAPT Fermentation Chamber on the top of the fridge
Unscrew the two Phillips head screws which hold the side service panel in position
Slide the side service panel away from the RAPT Fermentation Chamber
Remove the blanking plate and slide in the PCO1880 threaded plate into the desired location depending on if you wanted the ball lock disconnect mounting point on the side or the top of the fridge
Screw a duotight compatible carbonation cap onto the PCO1881 thread
or the KL10788 Carbonation Caps
Measure and cleanly cut the desired length of EVABarrier tubing required to reach from your fermenter in the fridge to the duotight BlowTie Spunding Valve or Inline Regulator. Then route this hosing into the injection moulded channel and through the opening in the top of the fridge
Unscrew the two screws which hold the RAPT blanking plate onto the mounting points
Secure the duotight BlowTie Spunding Valve or Inline Regulator into position using the two mounting points
Terminate the line inside the RAPT fermentation chamber with gas disconnects. are recommended for this
Note: You may need to remove the gauge from the BlowTie Spunding or Inline regulator which is positioned to the right of the RAPT Fermentation Chamber and rotate this such that it is upright. This can be done easily by removing the two bolts which hold the gauge housing in place and pulling up on the gauge to remove it
Note: To ensure correct orientation install the Inline Regulator (KL15035) on the left hand side. Install the Blowtie spunding valve (KL15042) on the right hand side of the RAPT Fermentation Chamber
For detailed instructions showing how to install a duotight BlowTie Spunding Valve or Inline Regulator, then please refer to the following instructional YouTube video
An easy way to connect the EVABarrier hosing onto the carbonation cap is to use a duotight fitting. Below is just one example of how the EVABarrier gas hosing can be connected.
Push a 6.35mm x 8mm reducer onto the duotight compatible barb of the carbonation cap
Push an 8mm male x 8mm female elbow into the reducer
Cleanly cut an 82mm length of EVABarrier hose and insert this firmly into the BlowTie Spunding Valve or Inline Regulator and duotight reducer. Ensure that the arrow on the side of the Spunding Valve or Inline regulator is pointing towards the RAPT Fermentation Chamber
Push a 6.35mm x 8mm reducer onto the duotight compatible barb of the carbonation cap
Cleanly cut an 84mm length of EVABarrier hose and insert this firmly into the BlowTie Spunding Valve or Inline Regulator and duotight reducer. Ensure that the arrow on the side of the Spunding Valve or Inline regulator is pointing towards the RAPT Fermentation Chamber
The front panel at the base of the RAPT Fermentation Chamber is dismountable. In normal use it is held in place by magnets, to allow easy and convenient access to the drip tray which is mounted underneath the fermentation chamber. It is recommended to regularly check the drip tray and empty as required. To enable this, remove the four screws holding the front panel in place.
The RAPT fermentation Chamber comes as standard with a short temperature probe which measures the air temperature within the RAPT Fermentation Chamber.
If you were looking for higher accuracy temperature measurement by inserting a temperature probe into the thermowell of your fermenter you will need to install and calibrate a longer extension temperature probe (sold separately - KL22460)
For instructions to install and calibrate this longer extension temperature probe please refer to the instructional YouTube video or follow the steps below
Alternatively, Bonding a RAPT Pill Hydrometer via Bluetooth and using this as the tmperature probe is ideal as this unlocks the ability to have powerful, customised Fermentation Profiles with steps that can be triggered by temperature, time, gravity and rate of change of gravity!
To calibrate the extension probe:
Enter the menu by pressing Select
Set up two glasses of water. Ice water to one glass and add hot water to the second glass
Use the Up or Down arrows to navigate to Settings and press Select
Navigate to Calibration Point 1 and hit Select
Insert the temperature probe of the RAPT Fermentation Chamber into the glass of ice water while simultaneously measuring the temperature of the ice water using a calibrated external thermometer such as a KL23320 Digital Instant Read Thermometer. Wait for the temperature reading on both the RAPT Fermentation Chamber and the external calibrated thermometer to stabilise as much as possible.
Then adjust the temperature shown on the RAPT Fermentation Chamber (Calibration Point 1) to match the temperature measured on the external calibrated thermometer.
Press Select to lock in Calibration point 1 and move on to Calibration point 2.
Insert the temperature probe of the RAPT Fermentation Chamber into the glass of hot water while simultaneously measuring the temperature of the hot water using a calibrated external thermometer. Wait for the temperature reading on both the RAPT Fermentation Chamber and the external calibrated thermometer to stabilise as much as possible.
Then adjust the temperature shown on the RAPT Fermentation Chamber (Calibration Point 2) to match the temperature measured on the external calibrated thermometer.
Press Select to lock in this calibration point 2
In the event that you revert back to the standard probe that is preinstalled in the RAPT Fermentation Chamber, you can manually reset the temperature probe to the default settings.
NTC beta: 3950
NTC ref. temperature: 298.2
NTC ref. resistance: 100000
You can also select Forget Calibration in Settings. This will revert any saved calibration settings to default.
Manual calibration of the internal temperature probe can be performed using the same method as outlined for the extension probe.
Included with every RAPT chamber are spare hinges that allow for the orientation of the door to be changed from right side opening to left side opening.
The bottom hinges are accessed by removing the dismountable drip tray cover (above).
To access the top hinges, remove the top panel of the RAPT chamber.
Follow the above instructions for installing the inline regulator to remove the two front panels. Then remove the 6 screws holding the plastic top cover in place. Once the top hinge can be accessed, it is removed by unscrewing from the RAPT chamber.
To swap the door hinge side, remove the top right hinge. Then carefully lift the door off the bottom hinge pin and place in a safe place. Unscrew the bottom right hinge.
Perform this in reverse to install the left hinges. Install the left bottom hinge. Carefully align the door onto the left bottom door hinge pin. Then install the left top hinge and replace the top cover.
It is recommended that this is performed by two people to minimise the risk of damage during the process
Prior to beginning fermentation or hooking up any kegs to your gas line into the fermentation chamber it is essential to conduct a leak test.
It is best to conduct a pressure decay test on the fermenter itself and on the incoming gas line into the duotight inline regulator from the CO2 cylinder and regulator to ensure your entire system has no leaks.
This can be done easily.
Attach CO2 cylinder and regulator to the gas post of the RAPT chamber
Attach the disconnect from the inline regulator (inside the RAPT chamber) to your empty fermenter
Adjust the pressure on the regulator to 20psi
Turn the CO2 cylinder valve handles off
Wait two hours and ensure the pressure reading on the pressure gauge on the regulator has not changed
