S-TF40A-D Tubular Heat Exchanger

 S-TF40A-D Tubular Heat Exchanger

S-TF40A-D Tubular Heat Exchanger Description

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.

S-TF40A-D Tubular Heat Exchanger Operation

The S-TF40A-D tubular heat exchanger is a 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.

Heat Exchangers Frequently Asked Questions

Frequently asked questions (FAQ) in relation to the engineering, design and manufacture of our tubular heat exchangers.

More Info

Heat Exchangers Thermal Calculation

The critical issue when designing the heat exchanger is the determining of the thermal exchange coefficients reliably and accurately.

More Info

Corrugated Tube Heat Exchangers

A corrugated tube is a pipe with a helical groove obtained from a plain tube by cold forming. The number of starts of the helix can be changed as well as the angle to optimize the heat transfer and performance.

How to avoid intergranular corrosion?

One of the main problems of the austenitic stainless steel can be the intergranular corrosion. Despite of its name, stainless steel is a material that is susceptible to be corroded or oxidized
