For thermal solutions for viscous food the ViscoLine range is a series of highly efficient heat exchangers that have been designed to handle your food processes in the most gentle manner.

Beverages and viscous food, as well as other products, often either have high viscosity or contain particles of many different kinds. In such cases, tubular heat exchangers are often the most practical solution for heating or cooling the product.

Alfa Laval ViscoLine™ is a range of highly efficient tubular heat exchanger types that incorporates corrugated tubes or other advanced profiles designed to increase turbulence in the flow of the media to be cooled. This substantially increases the overall heat transfer coefficient.

ViscoLine Multitube unit

The ViscoLine Multitube Unit is one of the most widely used thermal solution for viscous food. An ideal unit for heating, cooling and pasteurizing products with low and average viscosity, and products that contain fibres and small particulates.

ViscoLine Monotube Unit

Monotube installations are most frequently used for heat-treating products that contain large particles, or have a high pulp or fibre content. The Monotube heat exchanger consists of a single tube mounted inside an outer shell.

ViscoLine Annular Unit

Annular models are used at higher viscosity levels where it is necessary to apply heat to the product from both the inside and the outside at the same time, in order to prevent layering. In this tube-in-tube-in-tube model, the product flows between the inner and middle tube.

ViscoLine Regenerator Unit

The product flows counter-currently in the tubes and the media shell. This makes it possible to conduct product to- product regeneration. The ViscoLine Regenerator Unit consists of a removable bundle of tubes mounted inside an outer shell, and welded onto tube plates at both ends.

ViscoLine CIP Unit

The CIP Unit is ideal for hot water and heating cleaning liquids. Products can contain fibres & small particulates.

How it works

How it works

Tubular heat exchangers consist of an external shell and a single inner tube (monotube type) or a bundle of inner tubes (multitube type). The annular space type features a triple tube (tube-in-tube-in-tube).

ViscoLine tubular heat exchangers are distinctive for their use of tubes with a corrugated or dimple profile. They feature a hygienic design for use in aseptic applications and are part of a comprehensive range of fluid handling products in which the internal and external surfaces can be polished to meet individual clients’ specific requirements.

ViscoLine tubular heat exchangers comply with international regulations including PED.
