Product catalog summary

Overview: The ST Tube in Tube Heat Exchanger is designed for industries dealing with fluids of high viscosity, density, or contamination with fibers or solid particles. Its large tube diameter facilitates free flow, and its dismountable design allows for mechanical cleaning. Constructed with corrosion-resistant materials, it ensures a long service life.

Applications:

Sewage treatment plants for cooling or heating wastewater and sludge
Paper industry
Chemical industry, such as heating pastes in PET pellet production
Food & beverage industry

Construction:

Composed of multiple sections connected in series with knee pipes, mounted on a frame
Each section includes a smaller diameter tube inside a larger diameter tube
Number and size of sections depend on thermodynamic parameters
Compensators are used for significant temperature differences
Option for welded joints instead of flanges on the shell side

Advantages:

Simple, dismountable construction for easy cleaning
Expandable heat exchange area by adding sections
Corrosion-resistant stainless steel construction
Easy assembly
Flexible design with various tube diameters and module lengths (3m and 6m)

Working Parameters:

Maximum temperature: 230°F / 110°C
Maximum pressure: Product side: 232 psi / 1.6 MPa, Shell side: 145 psi / 1.0 MPa

Adaptable construction for higher working parameters.

Materials:

Inner tube (product side): Stainless steel 316L / 1.4404
Outer tube (shell): Stainless steel 304L / 1.4307
Frame: Stainless steel 304L / 1.4307

Exemplary Media: Water, wastewater, sludge, suspension, paste, slurry, and other media with fibers and solid particles, or high viscosity/density liquids.
