C Series

The Alfa Laval C Series is specially developed to give dairies an ideal solution for cold milk skimming. Milk is more viscous at lower temperatures, which puts higher demands on separation performance. With Alfa Laval’s unique, bottom-fed Hermetic Design, superior skimming efficiency is achieved without compromising the cream quality. The C series of cold milk separators therefore set the industry standard for cold milk skimming.

Dairy PX 18 A, H, C, W, WD and BM Series

True hermetic technology for cold milk skimming

  • Only Alfa Laval’s Hermetic Design can deliver a premium result with high cream concentrations at low temperatures
  • 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

A superior range of cold milk skimming separators

The Alfa Laval C series of separators is carefully designed to secure long run times without heating up your milk. Due to the viscosity and characteristics of cream at lower temperatures, hermetic separation is the only feasible solution in cold milk skimming. Only Alfa Laval’s unique bottom-fed concept provides true hermetic separation performance with increased flexibility to adjust to varying process conditions. Additionally, Alfa Laval’s innovative eMotion™ technology prevents excessive heating of the product, while minimizing the separator’s environmental footprint. High-grade, corrosion-resistant stainless steel is used for our C Series cold milk separators to meet the highest hygienic standards with low total cost of ownership over a long equipment lifecycle.


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.
