W and WD Series
Alfa Laval W and WD Series includes two types of models. The W models have been designed specifically for whey skimming. Our WD models can combine whey skimming and clarification in one stage. The W and WD Series is available in a wide range of sizes with innovative features to ensure efficient, reliable, and cost-saving operation.
Advanced technology that brings new benefits to whey processing
- Alfa Laval’s unique bottom-fed Hermetic Design provides superior skimming efficiency and maintains premium product quality
- The bottom-fed design reduces shear forces for gentle product treatment that preserves the size of the fat globules
- Hermetic seals on inlet and outlet prevent oxidation and reduce the foaming of the milk
- Easy adaptation to process conditions provides increased production flexibility and efficient CIP
- Energy savings of up to 60% thanks to the Hermetic Design
Two superior types of whey separators
The purpose of whey separation is to recover fat, while ensuring that the skimmed whey is as free from fat as possible. Low fat content is important for facilitating the downstream treatment and enhances the value of the whey. Alfa Laval’s W and WD separators have been designed for exactly this purpose. The WD Series combines clarification and skimming in one step, thanks to a clarification section inside the bowl that makes it possible to utilize pre-filtered whey (i.e., without using a whey clarifier first). Combining these in one step reduces both investment costs and the installation footprint.
Saving energy, cutting costs
Alfa Laval separators with Hermetic Design are the most energy-efficient on the market. When our unique eMotion technology is added, minimized air friction brings additional power reduction. Combined, our unique design and technologies can deliver up to 70% energy reduction compared to non-hermetic alternatives on the market.
Sustainable is our standard
Alfa Laval wants to help dairy producers make optimal use of every resource in their process. That’s why we build high-efficiency dairy separators that prevent product waste while consuming less energy and water, thanks to unique innovations. Letting you deliver top-quality products that leave a smaller environmental footprint.
Gentle acceleration, powerful efficiency
A unique air-tight bowl that enables improved product quality and drastically reduces power consumption.
Mechanical simplicicy for higher efficiency and lower costs
A direct-drive system with fewer rotating parts that minimizes both maintenance and energy costs.
New levels of capacity and hygiene
A radical new disc design that decreases cleaning needs while increasing flow rate by up to 20%.
Double the output per kWh
An innovation to minimize friction, which cuts the separator´s energy consumption and CO2 footprint by up to 70%.
Outstanding solids capacity
Continuous solid discharge ensures an intact and highly concentrated stream for onward processing or as a valuable by-product. This makes it possible to increase separation capacity.
Separators for every application
Alfa Laval was born from the invention of the modern milk separator. Today, we cover the full scope of dairy separation applications. With unique innovations to increase profitability and sustainability in your process, no matter your product. Check our full portfolio!
