BrewBuilt X3 Uni-Tank: Temperature Control Options Explained

 

This week we’re continuing our deep-dive series on the BrewBuilt X3 Uni-Tank, focusing on one of the most important parts of fermentation: temperature control.

One of the standout strengths of the X3 is its flexibility. Whether you want a simple, plug-and-play setup or you’re happy getting hands-on with more advanced hardware, there are multiple ways to control fermentation temperature. In this video we walk through the main options available, showing how each approach works in real-world brewing setups.

From basic fridge control through to fully integrated glycol systems, this episode is all about helping you choose a solution that fits your brewing style now, while still allowing room to grow later.

What This Video Covers

In this video we cover:

  • Using a larder fridge and temperature controller to create a simple and effective fermentation chamber for the X3

  • Pairing the X3 with the Kegland RAPT Fermentation Chamber for integrated, automated temperature control

  • Stepping into glycol cooling with Grainfather Glycol Chillers and GCA kits for precise control, cold crashing, and multi-fermenter setups

  • A premium approach using Brewtools FCS systems, including what they offer, how they integrate, and who they make sense for

Throughout the video we talk honestly about cost, complexity, expandability, and who each option is really aimed at, so you can make an informed decision based on your brewing goals.

Brew Day and Next Steps

If you’re brewing lagers, pressure fermenting, chasing tighter consistency, or simply looking to improve your fermentation control, this episode is well worth a watch.

The BrewBuilt X3 Uni-Tank is designed to adapt as your brewing develops, and understanding your temperature control options is a big part of getting the most from it.

You can explore the BrewBuilt X3 Uni-Tank and compatible temperature control solutions on the site, and follow along as we continue the X3 deep-dive series over the coming weeks.
