A PROJECT ?
In a professional brewery, precise control of temperature profiles and fermentation pressure is the primary guarantee of consistent flavor in your beers.
An unintended variation of a few tenths of a degree during a temperature rest, or poor management of the Cold Crash, can disrupt yeast performance, create off‑flavors (esters, diacetyl), or slow clarification. Designed by Brewtools, the FCS (Fluid Control System) provides a modular, connected automation solution to manage your entire cellar.
From glycol solenoid valve control to automatic pressure regulation on isobaric tanks, explore our complete guide and discover Brewtools FCS equipment for your fermentation room.
1. What is the Brewtools FCS system and what advantages does it offer your brewery?
The Brewtools FCS is a hardware and software automation platform designed to secure and digitize fermentation operations:
- Full autonomy and absolute repeatability: Program your fermentation profiles (temperature rests, rise/fall ramps, diacetyl rest, Cold Crash) and let the controller execute the instructions without human intervention during evenings or weekends.
- Intelligent glycol regulation: Connected to your chilled‑water network or cooling unit, the FCS controller drives solenoid valves with precision to avoid thermal shock and maintain stable temperature to within a tenth of a degree.
- Pressure management and carbonation (Isobaric): Coupled with the gas‑regulation module, the FCS automatically manages counter‑pressure ( 𝐶 𝑂 2 ) during fermentation to achieve perfect spunding and secure closed transfers.
- Cloud monitoring & HACCP traceability: Track your temperature and pressure curves in real time on a computer or smartphone. The full data history can be exported to enrich your batch‑tracking sheets.
2. The key components of the Brewtools FCS ecosystem
The strength of the FCS system lies in its modular CAN‑bus network design, allowing you to add features as your brewery grows:
- The FCS Main Controller (Main Unit): The brain of the system. It includes an intuitive touchscreen, Wi‑Fi/Bluetooth module, and centralizes communication with all tank modules.
- High‑precision PT1000 Temperature Probes: Inserted into the thermowells of your fermenters. They offer ultra‑fast thermal response and laboratory‑grade measurement accuracy.
- Solenoid Valve Modules (Valve Controllers): Control motorized or solenoid valves on your cooling jackets in glycol‑water circuits (24V or 230V).
- Pressure Sensors & TC Pneumatic Valves: Mounted on the fermenter dome via Tri‑Clamp (34 mm or 1.5") to measure continuous pressure and release excess 𝐶 𝑂 2 while maintaining the ideal pressure setpoint.
3. Configuration guide: How to deploy FCS on your professional fermenters
| Configuration Step | Recommended Hardware / Action | Operational Benefit for Brewery |
|---|---|---|
| 1. Basic Thermal Control | FCS Controller + PT1000 Probe + Glycol Solenoid Valve | Automatic cooling regulation and stable setpoint temperatures without drift. |
| 2. Heating & Cooling Automation | Add heating mat or thermal belts on dual‑channel controller | Dynamic management of warm fermentations (Saison, Kveik) or temperature rises for diacetyl rest. |
| 3. Advanced Isobaric Management | Add TC pressure sensor + 𝐶 𝑂 2 regulation valve Pneu‑Kit | Automatic spunding, integrated natural carbonation, and zero pressure loss. |
Rolling Beers Pro Technical Team Insight
Think about network centralization in your cellar area! The Brewtools FCS architecture relies on a robust wired connection between modules via CAN‑bus cable, combined with Wi‑Fi connectivity for Cloud data upload. To ensure optimal operation in the metallic and humid environment of a fermentation cellar, make sure to deploy a dedicated Wi‑Fi repeater in your workspace. This will allow you to monitor and adjust the settings of all your fermenters from your office or smartphone with complete peace of mind!
