Desulphurisation of mute must
Ensure your wine’s purity by efficiently removing sulfur dioxide, safeguarding its chemical and sensory qualities while minimizing waste and energy consumption.

Eliminates Sulfur Dioxide from Mute Must
The C 37 Desulphuriser from Cadalpe is a vacuum-operated system designed to efficiently eliminate sulfur dioxide from mute must, making it an essential solution for wine producers and beverage manufacturers. This equipment features a unique combination of a descending veil and a stripping column, ensuring brief contact times and optimal heat output, reducing contamination risks. The system’s patented sulfur dioxide absorption chamber minimizes lime consumption and results in easily disposable calcium sulfite solids, enhancing both operational efficiency and environmental safety.
With its automatic, continuous-operation design, the C 37 integrates seamlessly into existing processing lines—ideal for producing low-sulfite or sulfite-free products. The central control panel, equipped with electronic instruments, facilitates easy monitoring and adjustment of the primary process stages, ensuring consistent quality and performance. Additionally, the washing system allows for efficient in-place cleaning, reducing downtime and maintenance requirements. Engineered to preserve the chemical and organoleptic properties of the end products, the C 37 offers robust performance in demanding production environments, making it a reliable choice for facilities focused on excellence and sustainability.
