Corrugated tube shell and tube heat exchangers have many benefits and advantages over comparable smooth tube versions:

• Compact tubular heat exchanger; in some cases less than half the size of a traditional plain tube heat exchanger.
  
  
• Long running times due to turbulent flow
  
  
• Very low maintenance costs, minimum spares requirement.
  
  
• Lower heat transfer areas. Heat transfer coefficients of up to 2½ times higher can be generated. Due to the higher coefficients achieved, the heat exchanger size can be reduced by as much as half.
  
  
• Fouling caused due to ‘burn on’ freezing or chemical changes is minimised due to the turbulence created by eddies at the periphery or the tube wall.
  
  
• High response to CIP, which is increased because of the increased turbulence generated by the corrugated tube at traditional circulation velocities. In-situ cleaning is improved because of the increased turbulence generated by the corrugated tube, which in lower viscosity fluids minimises the tendency for deposition fouling to occur.
  
  
• Wide choice of MOC. Heat exchangers can be made in SS 304 / L, 316 / L, CuNi, Hastelloy, Alloy 20, Duplex, Titanium, etc.
  
  
• Uniform thermal processing.Increasing the tube side heat transfer coefficient brings the temperature of the tube wall closer to the temperature of the bulk fluid, minimising fouling.
  
  
• More flexibility in annular space sizing. There is no significant obstruction to the flow area of the tube so that they can be used for fluids with a high solid or fiber content with no fear of blockage.
  
  
• Monotube ‘DT’ series can handle large particles up to 50 mm size.
