M line

Alfa Laval M line range is used in the same hygienic applications as the BaseLine range, but M line is selected when higher design pressure or when extra-long plate packs are required. M line and BaseLine are heat exchangers used in dairy, food, beverage, and other hygienic applications. They are competitive choices for hygienic processes and utility applications.

Meets all hygienic heating and cooling requirements

Alfa Laval M line meets all requirements for pasteurization and other heating and cooling duties in hygienic applications.

Efficient design

Alfa Laval M line uses FDA-compliant glue-free gaskets and is easy to open for inspection and cleaning or to clean by means of Cleaning-In-Place (CIP). The plate configuration is flexible which means adding or removing plates is easy if process parameters change.

Plate types for different hygienic needs

M line is available with two different plate types:

  • Chevron type plate pattern is used in a wide range of industries. This ensures good distribution of the product as well as high thermal efficiency.
  • Gemini double wall consists of two plates pressed together. It prevents cross contamination between fluids in case of leakage through the plates.

The competitive choice

M line is in a competitive choice for hygienic processes and utility applications in dairy, food, and beverage industries. Examples of applications are:

  • Simple pasteurization
  • Raw milk cooling
  • Utility media heating/cooling
  • Cleaning-In-Place (CIP) heating

Alfa Laval FrontLine is recommended for more heat sensitive products or for products containing pulp and fibres.

Peace of mind

Alfa Laval global service network is never far away.

How it works

The heat transfer area of a gasketed plate-and-frame heat exchanger consists of a series of corrugated plates, assembled between the frame and pressure plates, which retain the design pressure. The sealing between the plates is made of gaskets. For the highest thermal performance and to enable a very close temperature approach, fluids normally run counter-currently through the heat exchanger.

M line is available with various pressing depths and angles of the chevron pattern and various shapes of the corrugation which are carefully designed and selected to achieve optimal performance. The chocolate pattern distribution area is a design feature that ensures fluids are evenly distributed across the entire plate. The result is that the entire heat transfer surface is fully utilized and stagnant zones that can result in fouling are avoided.

High flow turbulence between plates results in higher heat transfer; however, the consequence is pressure drop. Our thermal design engineers will help you design and select the model and configuration that is suitable for your application needs while delivering maximum thermal performance and minimizing pressure drop.
