HL2
Ion exchange
Effective reduction of potentially oxidizable polyphenols in an efficient, easy to apply and sustainable process.
This is how HL2 works
After several years of research, we have developed a technique for the reduction of polyphenols, mainly catechins, which guarantees a reduction of colour in the must without negatively altering its organoleptic qualities.
The HL2 system is based on the principle of Ion Exchange, which consists of the substitution of ions of the same sign between a mobile phase, the must/wine (A-), and a stationary phase, the resin (B+), through its functional groups.
This resin selectively removes the desired ion while respecting other ions present in the medium.
After a long R&D process, we have developed a specific resin with a special activation process called HL2.

Advantages
- Elimination of oxidizing agents and oxidizing precursors through ion/anion resin exchange.
- Anthocyanin removal.
- Elimination of unwanted odors (smoke taint).
Great advantages for start-up and operation:
- Autonomous and automatic.
- Simple and intuitive. A simple touchscreen that requires no computer knowledge.
- Exhaustive traceability at all times of flow, consumption and levels of each additive, as well as working times.
- Compact equipment with reduced dimensions with regard to the level of flow it can treat. Requires no special installation in the winery or additional equipment or components.
- Equipment available in different sizes.
- Easy connection to the winery’s own network, making it possible to manage all processes through the internet connection. This can even be controlled from another PC or even a smartphone.
- It has an automatic neutralization system. The discharges from the different stages will be neutral and thus the treatment plant biological systems will be protected.
