A PROJECT ?
In the financial and operational management of a professional brewery, the occupancy time of fermenters and conditioning tanks (Brite Tanks) directly determines your overall production capacity.
Waiting several days for a batch to reach CO₂ saturation through simple over‑pressurization from the tank dome slows down tank turnover. Integrating a stainless‑steel carbonation stone (Carb Stone) at the bottom of the tank allows gas to dissolve instantly at the core of the liquid through micro‑diffusion.
Discover how this sanitary equipment improves the profitability of your cellar and explore our selection of professional carbonation stones and pressurization accessories.
1. Profitability calculation: Why the Carb Stone is cost‑effective from the very first batches
Installing a carbonation stone provides three immediate economic and technical benefits to your brewery:
- Reduced conditioning time (Accelerated tank turnover): By reducing gas bubble size down to 0.2 µm, the contact surface between CO₂ and beer increases by thousands. Carbonation that previously required 4 to 7 days through passive diffusion now takes only 12 to 24 hours. You free up your fermenters more quickly for the next batch.
- Drastic savings in industrial CO₂: Unlike headspace saturation, where a significant portion of CO₂ is lost during safety venting, micro‑porous injection ensures an absorption rate close to 100% in cold liquid (0 to 4 °C).
- Foam stability and organoleptic quality: Fine gas dissolution promotes stable saturation, delivering elegant effervescence and a denser, longer‑lasting foam head at service.
2. Hardware configurations: From standard threading to sanitary Tri‑Clamp connection
Depending on your tank setup (isobaric or Brite Tanks) and your cleaning protocol, several formats exist:
- Carbonation stones with 1/4" NPT / BSP threading: The modular and economical solution. Screws directly inside a Tri‑Clamp adapter with bulkhead fitting (NPT/TC), allowing the stone to be mounted on any standard TC 1.5" port on your fermenter.
- Brewtools carbonation stones & TC 34 mm kits: Designed specifically to meet strict sanitary requirements. Mounted on a Mini Tri‑Clamp flange (TC 34 mm), they fit easily into lower ports on the shell or cone and include an integrated check valve to prevent beer backflow into the gas line.
- Dual‑use (Wort oxygenation): Used during transfer of hot/chilled wort into the fermenter, the carbonation stone also diffuses pure oxygen (O₂) to ensure an ideal dissolved oxygen level (8 to 10 ppm) and guarantee a vigorous fermentation start.

Golden rule: NEVER touch the sintered stainless‑steel body with bare hands! The 0.2 µm micro‑pores of a carbonation stone clog extremely easily when exposed to skin oils, hop residues, or grease. Always handle it with clean, disinfected nitrile gloves. After each use, perform an acid descaling, followed by hot‑water rinsing and sterilization by steam or immersion in a disinfectant solution. If the stone appears clogged, run hot water through it in reverse (back‑flushing) under pressure to clear the micro‑channels!
