Introducing Teralba’s Industrial Tube in Tube Heat Exchangers
Where efficiency meets durability in industrial heat transfer.
The Teralba industrial tube-in-tube heat exchanger, built with our dimpled tube technology, is a rugged system engineered to handle abrasive, viscous, and corrosive industrial fluids. The simple yet effective double-tube design ensures reliable heat transfer while minimising fouling and maintenance requirements.
As a tube in tube heat exchanger manufacturer in Australia, Teralba provides solutions that deliver consistent, energy-efficient performance across industries such as mining, chemical processing, oil and gas, and wastewater management.
The dimpled tube technology provides turbulence enhancement, by the creation of eddies and vortices in the flow behaviour. This breaks up boundary layers, introducing mixing effect, in a manner very similar to conventional inserted mixing elements, without the fouling issues.
Optimised Dimpleflo tube profiles to reduce fouling and scaling, extending service intervals. Dimpleflo technology includes unique self-scouring feature, where the induced turbulence creates a jostling effect within the tubes. Many Dimpleflo, working on tricky liquids/slurries such as high% solids sewage with stringy matter entrained, remain unopened after 5 years of service. That is what we call low maintenance!
Teralba designs Dimpleflo tube-in-tube heat exchangers for the toughest conditions. With precise engineering, heavy-duty componentry, and reinforced construction, they deliver maximum heat transfer, minimal downtime, and long-term reliability, both in Australia and abroad.
Suited for heating, cooling, or pasteurising a wide range of fluids, even under challenging operating conditions.
The dimpled tube design allows for a smaller overall heat exchanger footprint than competing systems, freeing up valuable floor space, simplifying installation and integration, and still delivering high heat-transfer efficiency—often matching or exceeding much larger units.
Teralba tube in tube heat exchangers are deployed across industries, including chemicals, mining, energy, water treatment, and manufacturing. Their ability to manage abrasive, viscous, and high-temperature fluids makes them ideal for demanding process duties. By delivering dependable heat transfer in challenging environments, they support efficient and uninterrupted operations across Australia’s industrial sector.
Teralba is proud to be supplying its proprietary Dimpleflo® heat exchanger technology as part of Barwon Asset Solutions’ innovative Heat-as-a-Service demonstration project at the Breakwater maintenance depot in Geelong.

The Neuse River Resource Recovery Facility selected Teralba’s Dimpleflo® tubular heat exchangers to cool thermal hydrolysis process (THP) sludge prior to digestion — a critical step for stable biogas production and digester performance.
From the start, the Dimpleflo® units exceeded expectations, delivering reliable cooling and consistent efficiency under demanding conditions.
Only one incident was reported during operation, when a single unit appeared to be underperforming. Teralba’s technician promptly visited site and found the issue was caused by a broken control valve stem, not the heat exchanger itself. After the valve was repaired, performance returned to normal.
The client praised Teralba’s fast response and technical support, noting that the Dimpleflo® units have since continued to operate flawlessly.
Dimpleflo® – proven performance, backed by exceptional service.
At Southern Oils, Teralba’s Dimpleflo® tube-in-tube heat exchangers are driving greater efficiency and reliability in critical oil re-refining processes — consistently outperforming expectations and delivering proven, repeatable results.
Southern Oils, a leading name in sustainable oil re-refining, relies on Teralba’s Dimpleflo® technology for demanding thermal duties where reliability and performance are essential.
Since installation, the Dimpleflo® units have exceeded expectations, providing exceptional heat transfer efficiency and long-term operational stability under challenging conditions. The unique dimpled-tube design enhances turbulence within the product flow, significantly boosting thermal performance and energy efficiency compared to traditional smooth-tube systems.
Impressed by these results, Southern Oils has made multiple repeat purchases, expanding the use of Dimpleflo® technology across their operations. The combination of robust design, minimal maintenance, and outstanding service support from Teralba continues to reinforce a trusted partnership.

Our FAQs provide clear answers to common questions about Teralba’s industrial tube in tube heat exchangers. From performance and maintenance to installation and lifespan, this section helps you understand how our systems deliver reliable heat transfer in demanding industrial environments.
A tube in tube heat exchanger consists of one tube inside another, creating an annular space where fluid flows in opposite directions for efficient heat transfer. This design is particularly effective for industrial processes where durability, reliability, and minimal fouling are critical.
Are Teralba tube in tube heat exchangers suitable for heavy-duty use?
Yes. Teralba’s exchangers are engineered for rugged applications such as mining, chemical processing, and wastewater/sewage treatment. They are built from industrial-grade stainless steels, duplex alloys and exotic metals such as Titanium and are designed to handle abrasive, viscous, or corrosive fluids under continuous operation.
Industries that handle challenging fluids benefit most. Common sectors include mining (slurry heating and cooling), oil and gas (process fluid conditioning), wastewater (sewage sludge heating/cooling post THP process and energy recovery), and chemicals (heating/cooling corrosive liquids).
Absolutely. Teralba manufactures custom tube in tube heat exchangers to suit specific flow rates, temperature ranges, pressures, and product characteristics. Each unit is engineered to optimise efficiency and durability for the client’s process.
While shell and tube exchangers are widely used, tube in tube systems are better suited for viscous, abrasive, or contaminated fluids because of their straightforward geometry and higher tolerance for fouling. This makes them easier to clean and more reliable in industrial environments.
With proper operation and routine maintenance, Teralba’s tube in tube exchangers can last decades. Their heavy-duty stainless steel design resists corrosion and wear, even in harsh industrial environments. Many clients report consistent performance for 20+ years.
Maintenance is minimal compared to other exchanger types. Regular inspection, occasional cleaning to remove scaling or deposits, and monitoring of pressure drops will keep the system running at peak efficiency. Teralba’s design also allows for straightforward disassembly if required.
Yes. That’s one of its strengths. Teralba engineers specify materials and wall thicknesses that withstand aggressive chemicals, high-solid-content slurries, and dust-laden gases. For highly corrosive fluids, we can provide custom alloys beyond stainless steel.
Yes. The counter-current flow design allows for maximum heat recovery and efficiency, reducing overall energy costs. In wastewater/sewage and process plants, tube in tube heat exchangers are often used to cut operating expenses associated with fouling/blockages and ongoing heat exchanger maintenance.
Lead times vary depending on customisation and project size. Standard units are often available in a matter of weeks, while fully engineered systems may involve additional processing time through our facility. Being a customer-focus, agile organisation, Teralba will strive to manage your needs, every time. Almost 50 consecutive years and a huge proportion of customers returning for more Dimpleflo equipment says it all. We look after our customers!
