Tetra Pak® Tubular Heat Exchangers

​​​​​​​​​​​​​​​​​​​Tetra Pak® Tubular Heat Exchanger for food​ products

The Tetra Pak® Tubular Heat Exchanger is a tubular heat exchanger that has been successfully used by the liquid food industry for decades. Combining straight and corrugated tubes, it offers optimal performance, long production time and low maintenance costs.

Now we offer the options of 3-A certification  for many types of applications and EHEDG certification for product-to-water (P2W) applications, giving independent proof of excellent cleanability and hygienic design. ​​


A tubular heat exchanger for heat treatment of food products in a processing line

200 l/h – 60,000 l/h

Food products from low to high viscosity, with or without particles and products with fibres or pulp.


Floating protection system

Long service lifetime and enhanced food safety

The inner and outer tubes and the connections in the heat exchanger are floating, not fixed or welded. This allows for thermal expansion or contraction in the tubes without the risk of cracking. It eliminates the risk of product contamination (due to expansion cracking), enables the inspection of all parts, and secures easy exchangeability of parts.

Modular design

Flexibility to adapt design to needs

The frame, tubes and other components parts of the heat exchanger are assembled in such a way as to allow for easy dismantling and rebuilding. This makes it possible to customize the heat exchanger for different recipes, capacities, and to run different products. As a customer, you can choose what to focus on. It's not only about which product you plan to produce; the design also offers flexibility in terms of e.g. energy consumption vs. investment cost.

Heat exchanger protective panels

Great energy savings potential

Protective panels built around the Tetra Pak® Tubular Heat Exchanger encapsulate the equipment and contain the heat. This gives up to 6% savings on energy consumption. With added insulation, savings go up to 11%. The panels also increase operator safety since they reduce the risk of contact with hot surfaces.

Product-to-product heat recovery

Low energy consumption

In this type of heat exchanger, product that has already been heated can be run past cold incoming product in order to pre-heat it. This reduces the amount of energy needed to bring the new product up to pasteurization temperature. It is possible thanks to the floating protection system, which eliminates the risks of cracks, and therefore cross contamination of product.

Long, floating tubes

Reduces food safety risks

Our tubular heat exchangers with 6 meter tubes are the safest on the market. Their floating design makes it possible to offer compact and efficient heat exchangers without any risk of cracks in the tubes. The heat exchangers are extended horizontally, rather than being stacked vertically, which also enables easy access for maintenance.


Spring box

Enables free product flow and superior hygiene

An optional patented spring box holds the heat exchanger tubes in place without any need for inner dividers or similar devices. By removing these internal barriers, the spring box facilitates free product flow and eliminates potential hygiene blind spots. The spring box is ideal for products containing fibres, but works well for other applications too.



First to offer EHEDG certification

EHEGD certification is an option on a selected range of Tetra Pak Tubular Heat Exchangers, namely CM models for product-to-water (P2W) applications. Now popular CM multitube modules can be EHEDG-certified, giving independent proof of excellent cleanability and hygienic design.



3-A stamp of approval

In 2016, we met the American 3-A standard after the introduction of new smooth welding technology. Their tough requirements are that all product contact surfaces can be mechanically cleaned and dismantled easily for manual cleaning or inspection. 3-A approval is optional for all our product-to-product (P2P) tubular heat exchangers.
