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.

 

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.

Units can be supplied either of all welded construction with expansion bellows in the outer tube or with a dismountable inner tube. This method of construction removes the need for expansion bellows and allows the inner tube to be replaced.

 

Applications:

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

Typical applications include:

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

 

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

 

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.
Units can be supplied either of all welded construction with expansion bellows in the shell or with a dismountable tube bundle. This method of construction removes the need for expansion bellows and allows the tube bundle to be replaced.


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

 

Advantages:

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