SACOME Annular Space Heat Exchanger

S-TF40A-D Tubular Heat Exchanger

Annular Space Heat Exchanger with removable inner tube and axial product inlet.

Special heat exchanger design for products with fibers or pieces.

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

Tubular Heat Exchanger Description

S-TF40A-D heat exchanger is a tubular heat exchanger consisting of three or four concentric tubes. The product flows through the central annular space while the service does it through the outer and inner channels.

Advantages of tubular heat exchangers

Tubular heat exchangers are the most used heat exchanger configuration because of the good operation and versatility.

Corrugated Tube Heat Exchangers

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

How to calculate a heat exchanger

The key task for the thermal design of a heat exchanger is the sizing of the heat exchanger.

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

One of the main problems in the stainless steel coud be interganular corrosion.
