Rapt Fermentation Chamber

The RAPT Fermentation Chamber is a purpose-built, fully insulated temperature-controlled fermentation unit designed for homebrewers who take fermentation conditions seriously. Developed by Kegland and integrated with the RAPT ecosystem, this chamber gives brewers precise control over their fermentation environment - from active cooling and heating through to real-time monitoring via the RAPT app - all in one clean, dedicated unit.

What sets the RAPT Chamber apart from DIY fridge conversions and basic fermentation solutions is its seamless integration with the wider RAPT platform. Pair it with a RAPT Pill hydrometer or RAPT temperature controller and you have a fully connected fermentation setup that monitors gravity, temperature, and progress remotely — without lifting the lid. The chamber is built to accommodate a wide range of fermenters and is designed to maintain stable fermentation temperatures whether you’re lagering at 8°C or fermenting a Kveik at 40°C.
Whether you’re dialling in a clean lager, pushing a hazy IPA, or experimenting with temperature-stepped fermentations, the RAPT Chamber gives you the environmental control that separates good beer from great beer.
