SACOME Tube in tube Heat Exchanger

S-TF20-I Tubular Heat Exchanger


Tube in Tube Heat Exchanger. Non removable inner tube.

This monotubular heat exchanger is part of our new Sanitary Line of heat exchangers.

S-TF20-I Tubular Heat Exchanger Description

The shell & tube heat exchanger S-TF20-I is a monotubular heat exchanger consisting of two concentric tubes. The product flows through the inner tube while the service flows through the space between the two tubes.

Advantages of Tubular Heat Exchangers

Tubular heat exchangers (shell & tube heat exchangers) are the most common heat exchangers configuration used in the market.

Corrugated Tube Heat Exchangers

We have developed our own corrugation technology for the manufacture of our corrugated tube heat exchangers.

How to calculate a heat exchanger?

The suitable modelling of the thermal properties is the basis for an optimal design of the heat exchanger.

How to avoid intergranular corrosion? “L” or“Ti” Stainless Steel?

One of the main problems of the austenitic stainless steel can be the intergranular corrosion.
