Dimpleflo Tritube Heat Exchangers (also known as Triple Tube Heat Exchangers) are ideal for viscous fluids where product fouling, crystallisation and particles can inhibit heat transfer is shell and tube heat exchangers.

As the name implies, a Dimpleflo Tri-Tube heat exchanger is literally, a tube within a tube within a tube. The primary fluid or product flows between a central dimple element and a jacket tube. The cooling or heating fluid passes through both the central dimple element and an outer shell jacket in counter current. This configuration of heat exchanger enables processing of highly viscous and fouling product in a single flowpath with no moving parts., Dimpleflo Tritube Heat Exchangers can simultaneously handle high temperatures and high pressures. This combined with minimal gasketing and the “self-cleaning” effect of dimples, Dimpleflo Tritubes provide the optimum in longevity and low maintenance. The use of Dimple Technology for all tube components greatly increases the heat transfer coefficient and thermal performance of the heat exchanger. The removable dimpled inner tube allows for easy inspection of annular space or product flowpath.

Benefits and Features

  • Low sheer means high product integrity and little or no damage to the product from processing.
  • All Heat Transfer Tubes are designed to be self-draining
  • No moving parts. Maintenance requires only the replacement of a small number of O-rings.
  • Single product flow path eliminating tracking of product and reducing the opportunity of blockage
  • Heat Exchanger tubes can be made from stainless steel or alloys with high corrosion resistance.
  • Reduced pressure drop from low velocity and enhanced flow distribution
  • High heat transfer rate as a result of dimple turbulence enhancing technology
  • Low capital cost compared to scraped surface heat exchangers
  • Suitable for CIP cleaning and Aseptic processing.
  • Dimple effect results in low (if any) burn on of product.


  • Viscous sauces, syrups and toffees.
