Tube in Tube Heat Exchangers

Tube in Tube Heat Exchangers

Our range of Corrugated Tube Heat Exchangers use corrugated Tubes to enhance heat transfer. Two types of heat exchanger are available. The mono-tube design has a single tube within a tube and the multi-tube design has a number of tubes inside a shell.

Each design has variants for either industrial or hygienic applications.

The construction can be either all welded or with removable tubes for ease of maintenance.

Advantages:

  • Higher thermal efficiency due to corrugated tubes
  • Easy to clean
  • Low maintenance

Materials:

  • Product side in AISI 316, AISI 316L, Duplex steels
  • Service side in AISI 304
  • Other materials available on request

Options:

  • Stainless steel frame
  • Thermal insulation

Mono-tube design

 

Features

The mono-tube design comprises a single corrugated tube within a tube. The process fluid flows through the inner corrugated tube with the service fluid in the annular space between the inner and outer tube. 


Applications:

The mono-tube design is ideal for processing high viscous fluids and fluids containing large particulates or fibres up to 50 mm in diameter.

  • The mono-tube design is ideal for processing fluids containing large particulates or fibres up to 50 mm in diameter.
  • Sewage sludge heating
  • Effluent water cooling
  • Heating & cooling of sauces, purees & pulps
  • Laundry & dye-house effluent heat recovery
  • Milk, cream and juice heating
  • High temperature & pressure applications

Multi-tube Design
 

Features

The multi-tube design consists of a number of corrugated tubes within a shell. The process fluid flows through the inner corrugated tubes with the service fluid in the shell. 


Applications:

The multi-tube design is ideal for heating applications using steam, fluids containing fibres or small particles and slurries. Typical applications include:

  • Steam heating of water & CIP solutions
  • Water to water heat recovery
  • Fluid heating using thermal oil
  • High temperature sterilisation of milk, juices etc.
  • Exhaust gas cooling
  • High temperature & pressure applications
