Alfa Laval UniDisc™
Reach new heights – higher flow rate, better separation performance and superior hygiene – with the weld-free UniDisc™ design from Alfa Laval. Unlike traditional separator discs with caulks (disc spacers) welded to the plate, discs with UniDisc technology feature micro caulks molded from the metal plate itself during the form pressing process. These micro caulks increase the number of discs in the disc stack, increasing the separation surface area and boosting separation performance.
Experience the Benefits of Alfa Laval UniDisc™:
- Up to 30% increased separation efficiency
- Consistent, even flow of process liquid through the stack
- Expanded surface area for enhanced separation
- Improved product safety
- Higher flow capacity
- Faster, easier, and more cost-effective cleaning and maintenance
How UniDisc™ works
The UniDisc is pressed out of a single metal sheet to form a conical disc with disc spacers. These spacers are uniformly distributed across the disc surface, ensuring that the distances between the discs are even and resulting in a robust and rigid disc stack. The micro caulks are smaller and shorter than welded spacers, providing slightly more separation area and enabling more discs to fit into the disc stack. The actual increase in area depends on the size and type of separator.
UniDisc™: No magic, just innovation
With Alfa Laval’s innovative UniDisc™ technology, you can achieve up to 30% higher separation efficiency, along with an unprecedented level of hygiene in your disc stack separator.
Unlike traditional separator discs, which rely on welded caulks, UniDisc™ features micro caulks formed directly during the plate-pressing process. This breakthrough design results in a disc stack that delivers superior separation performance and exceptional cleanability.
It’s not magic. It is just another groundbreaking innovation from Alfa Laval.
