Upgrade Your Heat Exchanger Without Full Replacement
Save time, money, and hassle — replace the tubes, not the entire unit.
At Teralba Industries, we’re committed to providing smarter, more cost-effective solutions that extend the life and performance of your process equipment. One of our most valuable and unique offerings is our Dimpled Tube Retrofit Service — a specialized maintenance solution that allows you to replace worn or aging heat exchanger tubes with advanced dimpled tubes, without the need to replace the entire unit.
⚠️ The Challenge
Why Full Replacement Isn’t Always Necessary
When the performance of a heat exchanger begins to decline—often due to tube corrosion, fouling, or reduced thermal efficiency—the default recommendation is usually full unit replacement. This “rip and replace” approach might solve the immediate issue, but it comes with serious costs and operational disruptions that are often avoidable.
High Capital Expenditure
Replacing an entire heat exchanger can involve tens—sometimes hundreds—of thousands of dollars in new equipment, installation, and engineering adjustments. This isn’t just a purchase; it’s a major capital project that impacts your budget and long-term planning.
Extended Downtime
Full unit replacement means taking your system offline, coordinating trades, and often waiting weeks for new parts to arrive and be installed. That lost production time can be just as costly as the equipment itself—especially in high-output environments.
Plant-Wide Disruption
Heat exchangers are typically integrated into broader processing systems. Removing and reinstalling a new unit can require reconfiguration of piping, supports, and controls. This creates a ripple effect across your plant’s workflow, increasing risk and complexity.
💡The Smarter Solution
The Dimpleflo™ Tube Replacement Solution
Upgrade Your Heat Exchanger with Proven, Patented Dimpleflo™ Technology
At Teralba Industries, we believe you shouldn’t have to replace an entire heat exchanger just because the internal tubes have aged or corroded. That’s why we offer the Dimpleflo™ Tube Replacement — a smarter, more efficient way to restore and enhance your system’s performance without the time, cost, or disruption of full-unit replacement.
Replace the Tubes, Not the Unit
Our retrofit service involves carefully removing the worn or inefficient internal tubes from your existing heat exchanger and replacing them with Dimpleflo™ dimpled tubes — precision-engineered to significantly boost heat transfer and efficiency.
Retain Your Existing Setup
There’s no need to alter your infrastructure. The Dimpleflo™ tubes are custom-manufactured to fit perfectly within your current heat exchanger shell, maintaining the original layout and flow paths while delivering a major performance upgrade.
Custom-Engineered for Seamless Integration
Each retrofit is tailored to your specific equipment. Whether you're running a compact CIP system or a large-scale processing plant, our engineering team ensures the retrofit matches your application exactly — down to the millimetre.

Why Choose The Dimpleflo™ Tube Replacement?
When heat exchanger tubes begin to deteriorate, the traditional solution has been costly full-unit replacement. Teralba offers a better path forward. By retrofitting your existing heat exchanger with dimpled tubes, you gain access to cutting-edge performance advantages while avoiding the capital expense of new equipment.
Key Benefits of Upgrading to Dimpled Tubes
Boost Heat Transfer Efficiency
The Dimpleflo™ tubes disrupt the flow of fluid inside the tube, promoting turbulence that significantly improves heat transfer. This leads to faster thermal response and better control over your processes.
Increase Process Throughput
With improved heat exchange, your systems can handle higher product volumes in shorter cycles, enhancing overall productivity and allowing you to scale operations without expanding your plant footprint.
Reduce Energy and Operating Costs
Improved thermal efficiency means you use less energy to achieve the same or better outcomes. This leads to lower utility costs and a reduced environmental footprint.
Extend Equipment Life
By replacing only the internal tubes, you maintain the structural integrity of your current heat exchanger while eliminating worn-out components — extending the life of your asset and avoiding downtime associated with complete replacements.
Minimise Capital Expenditure
Avoid the significant costs of purchasing and installing new heat exchangers. Our retrofit solution is a smart, economical alternative that delivers long-term value.
Tailored to Your Existing Equipment
Our experienced technicians custom-fit the new dimpled tubes to your current setup, ensuring a seamless integration with your existing heat exchanger system.
