The Brewtools FCS One Starter Kit is the perfect way to begin using the Brewtools Fermentation Control System (FCS) on a Unitank. It combines the core FCS One controller with essential sensors and hardware to monitor and manage key fermentation parameters — helping brewers automate and optimise fermentation.

Key features

• FCS One DC24V Controller with power supply – central system controller compatible with Brewtools sensors and actuators.

• Density & Temperature Sensor (TC 1.5″, 300 mm) – measures real-time fermentation gravity and temperature.

• Pressure/Spunding Sensor + Solenoid Valve – enables automatic pressure control and spunding.

• Airlock & Mounting Accessories – includes a TC34 mm 2-part airlock, ball mount system, clamps and gaskets.

• Complete Cable + Adapter Set – various LP12 cables and DIN-43650 adapter included for quick setup.

What it does
This starter kit gives brewers real-time temperature, density (gravity) and pressure data throughout fermentation, feeding it into the FCS One controller so you can monitor progress and automate responses — such as pressure release (spunding) — without manual intervention.

Expandable system
As part of the modular Brewtools FCS ecosystem, additional sensors (e.g., level, agitators) or solenoids (e.g., for cooling) can be added later to increase automation and control.

Ideal for
Homebrewers & microbreweries looking to step up fermentation control without engineering the system from scratch — with professional-level monitoring and automation out of the box.
