The gas you use is critical to your Enomatic system’s performance and to keeping your wines tasting their best. While Enomatic machines can run on either **food-grade nitrogen** or **high-purity argon**, extensive testing shows that **argon offers superior wine preservation**. That’s why we recommend it for 99% of venues. For 99% of our clients, we recommend [D-size high purity argon from Supagas](https://www.supagas.com.au/products/ZXARGONHP). ### Recommended gas by model - **Unica Romas and Unica Starts:** High Purity Argon (E938) - **Unica Bubbles:** Food-grade Carbon Dioxide (E290, 100%) - **Unica Bag:** No gas required When designing cabinetry to fit your [D size gas bottle](https://www.supagas.com.au/products/ZXARGONHP), please note that the cylinder is taller once it has the regulator in place. The dimensions will be 745 H x 180 D mm. Argon purity levels - **High Purity Argon (HP, 99.99%)** – Ideal for hospitality wine service - **Ultra High Purity Argon (UHP, 99.999%)** – Used for lab or ultra-sensitive applications - The difference is negligible for wine, so **HP Argon provides the best balance of performance and value** ### Gas supply and consumption - **Supplier:** We recommend **Supagas** as they are available Australia-wide - **Cylinder size:** D-size for an 8-bottle machine. - **Duration:** Most hospitality clients find that they get around **6 months per D-sized cylinder** – depending on usage, bottle turnover, and system size. ### Best practices - Always use **food-grade, high-purity gas**. - Keep a backup cylinder on hand, if possible. - Check gas levels regularly and ensure connections are sealed properly. - Refer to the Argon gas safety data sheet (SDS) [here](https://www.winepreservationsystems.com/hubfs/3288378_001_001.pdf)or the Carbon Dioxide (C02) gas safety sheet (SDS) [here](https://www.winepreservationsystems.com/hubfs/3139255_001_001.pdf) for proper storage information. - [Overview](https://www.winepreservationsystems.com/knowledge-base/overview#main-content) - [Introduction to enomatics](https://www.winepreservationsystems.com/knowledge-base/overview#introduction-to-enomatics) - [Choosing your enomatic model](https://www.winepreservationsystems.com/knowledge-base/overview#choosing-your-enomatic-model) - [Self-service information](https://www.winepreservationsystems.com/knowledge-base/overview#self-service-information) [![Wine Preservation Systems](https://www.winepreservationsystems.com/hs-fs/hubfs/Wine%20Preservation%20Systems.png?width=400&height=133&name=Wine%20Preservation%20Systems.png "Wine Preservation Systems")](https://winepreservationsystems.com/) Copyright © 2026, Wine Preservation Systems
