Dimpleflo™ Difference

Dimpleflo™ Heat Exchangers are ideal for heating and cooling of viscous and fouling fluids. The Dimple profile induces turbulence deep into the fluid flow which increases Reynolds numbers. The coefficient of heat transfer increase as a result of Dimpleflo tubing is greater than the pressure drop penalty giving Dimpleflo a great return on investment.

Dimpleflo can withstand high pressures and temperatures in many cases beyond smooth tubing.

Dimpleflo™ profiles can be tailored to each application to optimise the rate of heat transfer.

Our Journey

From humble beginnings to industry leadership, our story reflects decades of innovation, growth, and commitment to excellence.
Discover how our milestones have shaped who we are today.
1988
Early-mid
Dimpleflo... a product with a trademark

Dimpleflo began with an idea, some prototypes and a series of heat transfer tests. With the product showing definite efficiency gains over plain tube, the inventor commissioned a PhD qualified chemical engineer, who built a heat transfer selection program that ran on Apple 2E computer.

1990's
Early
Food industry - a challenging start
By early 1990's Dimpleflo had become a recognised brand in the wine industry. The challenge of being able to handle difficult slurries and high viscosity fluids has been mastered and the trend to must cooling gives Dimpleflo the opportunity to flourish.
1992
30 September
Dimpleflo- into critical quality applications
With interest in a new product reaching new heights, applications came forward from biopharmaceutical sector. These include cooling of water-for-injection and temperature management of many other blood-related processes. Many units are incorporated and some remain in service as at 2024.
1996
30 September
Temperature managing of anaerobic digestate
1996 saw Dimpleflo grow into yet another sector. Wastewater processes need accurate temperature control to ensure that anaerobic digesting happens effectively. Dimpleflo proves itself as robust, and able to cope with high solids digestates, No maintanence is a definite plus.
2000
30 September
Heat recovery from hot, fouled, liquid wastes
Hot waste, entering city sewage is a problem that EPA demanded solved. Dimpleflo proved ideal. We removed existing equipment that was troublesome and required filtration prior to cooling and replaced with Dimpleflo. Another industrial sector opened up as heat energy was recovered and transferred to incoming town water, saving both the environment and the energy.
2007
30 September
Development of specialised heat transfer behaviour testing
With many installations completed and track records of success in challenging heat transfer duties, many of our customers came forward with their own liquids, and semi-solid mixtures for testing. These included shear-thinning, non-newtonian and more. A specialised, extended orifice testing device was commissioned so that critical heat transfer behaviour could be replicated and accurately incorporated into Dimpleflo heat exchanger selection program
2011
30 September
Oil re-refining... a natural progression
With the challenges of food-based products mastered, new challenge came forward from oil and gas sector. In oil re-refining contaminated oils are reprocessed to reclaim a clean, re-usable base product. Previously, conventional heat transfer equipment had fouled very quickly, causing issues and process interruptions. Dimpleflo surprised the trade with highly efficient heat transfer results and remarkable anti-fouling characteristics. Many repeat orders ensued, and are current.
2018
30 September
THP digestate cooling duties - USA
Wastewater treatment processes have evolved to include the recovery of commercially viable volumes of methane gas. Cooling the digestate after high temperature themal hydrolysis processes require heat exchangers that are fit-for-purpose, and reliable. With successful installations in Australia and New Zealand, Dimpleflo becomes the benchmark product in USA projects in Virginia, North Carolina, Kentucky and more.
