Product features in the design of a heat exchanger

The requirements and specifications of the client depend on each application and project. To adapt to the different requirements on internal and surface finish, we have 3 lines of tubular heat exchangers:

  • Sanitary line, for food applications, with special attention to finishes, CIP cleaning and drainability.
  • Pharmaceutical line, with certified roughness and special design to avoid cross contamination.
  • Industrial line, for compact, versatile and reliable designs.

Surface finish and quality

We have an extensive expertise and Know-How in the processing and treatment of products, with more than 4.500 worldwide references and an extensive product database, not only for industrial applications but also for food applications and pharmaceutical applications. Some of the most representative applications of our shell and tube heat exchangers are as follow:

  • Worts cooling.
  • Particulate products.
  • Tomatoes, soups and dressings.
  • Fruit juices and beverages.
  • Desserts.
  • Margarine.
  • Dairy.
  • Eggs and derivates.
  • Water for pharmaceutical uses.
  • Emulsions, lotions and cosmetics.
  • Others pharmaceutical products.
  • Vegetable oils and animal fats.
  • Wastewater, sewage and sludge.
  • Biogas.
  • Biodiesel.
  • Water and CIP heating.
  • Steam condensation.
  • Exhaust gases.
  • Vacuum gases.
  • Paints.

We can also characterize the behaviour of the product in an accurate way, through laboratory tests, where we determine the main properties of the product:

  • Density.
  • Specific heat.
  • Thermal conductivity.
  • Viscosity.

This tool is especially useful for the characterization of non-Newtonian fluids, very common in food applications, and whose complex behaviour depends not only on the temperature, but also on the process speed.

Definition of the process in the design of heat exchangers

The main process data that the client must define to design a heat exchanger are the flows, both product flow and service flow, as well as the inlet and outlet temperature. These parameters should verify the principle of conservation of energy. Other process data that may be important depending on the application are the inlet pressure, the maximum admissible pressure drop or flow rate.

Heat exchanger design

The work of the designer consists of:

Select the right heat exchanger geometry for the process.

we have different configurations to achieve the optimal performance of the heat exchanger:

TF20-I. Tube in tube heat exchanger. Non-removable inner tube.

Within this geometry, and depending on the application, a selection of different heat exchangers are available:

S-TF20-I sanitary tube in tube heat exchanger
P-TF20-I pharmaceutical tube in tube heat exchanger
I-TF20-I industrial tube in tube heat exchanger

TF20-D. Tube in tube heat exchanger. Removable inner tube.

Within this geometry, we have our S-TF20-D Tube in tube heat exchanger.

TF40A-D. Annular space heat exchanger. Removable inner tube. Axial product inlet.

Within this geometry, we have our S-TF40A-D anular space heat exchanger.

TF40R-D. Annular space heat exchanger. Removable inner tube. Radial product inlet.

Within this geometry, we have our S-TF40R-D sanitary heat exchanger.

TF40AH-D. Annular space heat exchanger. Removable inner tube. Special design for high pressure.

Within this geometry, we have our S-TF40AH-D sanitary heat exchanger.

TFM-I. Multitube heat exchanger. Non-removable tube bundle.

Within this geometry, and depending on the application, a selection of different heat exchangers are available:

S-TFM-I Sanitary heat exchanger

P-TFM-I Pharmaceutical heat exchanger

I-TFM-I Industrial heat exchanger

For this geometry, we have our V SERIES multitube heat exchanger. This shell and tube heat exchanger is made-to-stock production being an effective and economical solution.

TFM-D. Multitube heat exchanger. Removable tube bundle.

Within this geometry, we have our I-TFM-D multitube heat exchanger.

TFMP-I. Multi-pass heat exchanger. Non-removable tube bundle.

Within this geometry, we have our I-TFMP-I Multi-pass industrial heat exchanger.

TFMU-D. Multi-pass heat exchanger. Removable U tube bundle.

Within this geometry, we have our I-TFMU-D Multi-pass industrial heat exchanger.

Heat exchanger according to the recommendations of the TEMA code.

SACOME designs and manufactures industrial heat exchangers following the recommendations of the TEMA code. Within this geometry, we have our TEMA heat exchanger.

Perform the thermal calculation of the heat exchanger to achieve the desired temperatures.

The technology of corrugated tube developed by SACOME allows to reduce notably the length of the equipment and / or the number of interconnected units, with respect to a tubular heat exchanger of smooth inner tubes. The corrugation increases the turbulence, improving the coefficient of heat transfer and getting a much more compact heat exchanger.

Perform the mechanical design og the heat exchanger.

The designer must check that the selected thicknesses for each element (inner tubes, shell tubes, tube bundle, connections, etc.) are in accordance with the required design code AD2000-MERKBLÄTT, ASME Section VIII Div. 1, EN 13445 or PD5500, among others.
