Annular Space (AS)

Annular Space (AS)

A concentric-tube heat exchanger for smooth-flowing, homogeneous products.

The AS Annular Space heat exchanger is designed with two concentric tubes to create an annular product flow path. This geometry ensures uniform heat exchange with minimal shear, making it ideal for sensitive, low-viscosity products such as plant-based beverages, milk alternatives or syrups. Its hygienic design supports easy cleaning and integration in both heating and cooling operations.

Annular design ensures uniform heat transfer
Low shear treatment, ideal for delicate fluids
Fully hygienic and CIP-ready, ensures food safety
Efficient thermal exchange, with compact design
Suitable for heating and cooling, with stable flow

Versatility of use

Designed to be integrated into different production lines and products.

Oat, almond or soy drinks

Juices and infusions

Fermentation broths or sugar solutions

Plant-based milk concentrates
