Large Heat Exchangers for High Pressure & Corrosive Environments, Stack Systems & Cladding
The industry’s largest heat exchangers with deep application, installation, and maintenance expertise
We partner with the petrochemicals and refining sector to deliver large heat exchanger solutions that simplify integration and reduce overall footprint.
The petrochemicals and refining sector uses heat exchangers on a huge scale – but that’s a major challenge when space is at a premium. Worse, integrating rental heat exchangers when equipment fails becomes a costly, time-consuming process that extends downtime and interrupts production for longer.
At Aggreko, we provide the industry’s largest heat exchanger rentals, offering higher pressure and temperature ratings for demanding, large-scale operations. Using our design expertise and exclusive fleet, we’ll help you:
- Reduce overall heat exchanger footprint compared to several smaller units.
- Simplify your operating environment.
- Support high pressures, high temperatures, and corrosive fluids.
- Save time and money with fewer connections and less piping.
- Transfer heat on a huge scale with sizes up to 5,700 sq. ft.
- Reduce your carbon footprint by reducing overall heat exchanger requirements.
Built for the most demanding heat exchanger applications
- Reduce your overall heat exchanger footprint by replacing multiple smaller heat exchangers with one all-encompassing solution. Our experts will help you see the opportunities to simplify your environment and, in turn, reduce the costs and complexity of intricate pipework and connectivity.
- Handle corrosive fluids with confidence using a large shell and tube heat exchanger. Our corrosive environment heat exchanger solutions are built from carbon steel with stainless steel cladding on the shell side – ideal for applications like working with low-temperature sour water in refineries.
- Reduce your maintenance overhead with a single large-scale heat exchanger to manage and fewer points of failure than multiple individual heat exchangers working side by side. Our large-node heat exchangers are also easy to locate and install with a galvanized skid for easy transportation.
- Improve and optimize your processes with insights from Aggreko Process Services (APS). Our senior process engineers are ready to design a turnkey solution around your challenges, then support you through Management of Change (MOC).

- Carbon steel shell with stainless steel cladding – This construction enhances durability and corrosion resistance, making them suitable for low-temperature sour water applications and environments with aggressive chemicals.
- Chrome molybdenum alloy steel channels – These components provide high levels of strength and longevity, reducing the risk of mechanical failure under extreme conditions.
- Compact, high-efficiency design – The large node heat exchangers replace multiple smaller units, reducing the total equipment footprint while simplifying installation and operation.
- Industry-exclusive rental offering – We’re the only rental company providing large node heat exchangers, making them a unique solution for industries needing high-performance temporary heat transfer equipment.
These features make our large node heat exchangers ideal for projects requiring rapid deployment, scalable performance, and superior thermal efficiency.
Yes, we offer a rapid replacement service to ensure continuous operation if a large node heat exchanger requires maintenance during the rental period. These units are designed for quick installation and removal, preventing prolonged downtime and operational disruptions.
To facilitate seamless unit replacement, we provide:
- Quick deployment and removal – Each heat exchanger is delivered with adapter spools and a galvanized skid, simplifying integration into existing process systems. These features enable faster setup, reduced downtime, and improved flexibility during maintenance events.
- Minimized production losses – If a unit requires servicing, we can quickly deploy a replacement, ensuring that operations continue with minimal disruption. This approach is particularly beneficial in industries where unplanned outages can result in significant financial losses.
- Certified maintenance process – We follow strict cleaning, inspection, and certification procedures before redeploying any rental unit. Every heat exchanger undergoes extensive quality control checks to confirm thermal efficiency, structural integrity, and compliance with industry safety standards before being reintroduced into service.
- Engineering and technical support – Our team of engineers and process specialists provides on-site and remote technical assistance, ensuring that heat exchangers are installed, operated, and maintained correctly.
With this fully managed rental and service model, we ensure you receive reliable, high-performance heat exchangers with minimal downtime, even in the event of maintenance needs.
Our large node heat exchangers are specifically designed for demanding industrial environments where high temperatures, high pressures, and corrosion resistance are critical. These exchangers play an essential role in:
- Petrochemical and refinery operations – Used for process cooling, vapor condensation, and high-temperature heat transfer, ensuring stable refinery operations. Large node heat exchangers can handle hot hydrocarbons, crude oil processing, and fluidized catalytic cracking (FCC) units, making them a key component in the refining process.
- Chemical processing plants – Used to support reactor cooling, solvent recovery, and temperature control for exothermic reactions, ensuring safe and efficient production. These units prevent thermal imbalances, helping to maintain precise process conditions in facilities handling highly reactive or heat-sensitive chemicals.
- Energy generation facilities – Large node heat exchangers play a role in turbine cooling, steam condensation, and waste heat recovery, allowing power plants to optimize energy efficiency and reduce operational costs.
- Heavy manufacturing and metal processing – Used in thermal control for metal casting, forging, and industrial furnace operations, where precise heat exchange is necessary to prevent overheating, warping, or structural failure in metal components.
- Offshore and maritime industries – These exchangers help regulate engine and generator temperatures in drilling platforms, FPSO (Floating Production, Storage, and Offloading) vessels, and other offshore installations.
With their high thermal efficiency, robust design, and rapid deployment, our large node heat exchangers support critical industrial applications that require reliable, high-capacity heat transfer solutions.
