Alfa Laval Hermetic Design™
Our unique airtight separator provides gentle product handling, smooth flow and maximum product quality. We call it Alfa Laval Hermetic Design™. It reduces shear force, lowers power consumption and prevents oxygen pick-up. An environment without any air in the process fluid ensures better process control and optimal process conditions. With Hermetic Design, the separator consumes less energy, due to the favourable fluid dynamics inside the bowl. The design also optimizes the cleaning-in-place (CIP) cycle, ensuring the CIP fluid comes into contact with all product-wetted parts.
Experience the benefits of Alfa Laval Hermetic Design™:
- Gentle product handling with smooth flow
- Higher separation efficiency
- No loss of volatile components
- Preserved product quality and enhanced yield
- No oxygen pick-up for better process control
- Up to 60% less power consumption compared to traditional top-fed alternatives
- Improved process conditions with air-free environment, preventing foaming
- Efficient CIP, all internal surfaces remain completely wetted
- Gentle acceleration of shear-sensitive material
How Hermetic Design™ works
From the separator’s airtight bottom-fed inlet zone, feed enters the separator through a hollow spindle, which prevents oxygen pick-up. The bowl with its carefully engineered outlets effectively eliminates any air-liquid interface inside the separator. Low shear in the feed inlet zone secures gentle product acceleration into the separator, and low shear in the bowl ensures gentle product handling during the separation process. This minimizes product loss and increases separation efficiency. Hermetic Design prevents the destruction of the cell walls for biotech processes and emulsification in dairy and edible oil processes.
