Heat exchangers based on plate frame are very popular for their miniaturized size, high thermal performance, and simple maintenance. They are constructed by stacking thin sheets, and so efficient heat exchange between fluids is possible without mixing. Such exchangers are suitable for the usage in the applications like HVAC, food & beverage and chemical industry owing to the pressure and temperature and pressure capability.

Shell & Tube Heat Exchanger: The Shell and tube heat exchangers segment has dominated the market in 2024. Shell and tube heat exchangers are the oldest and most widely used kind of heat exchangers in virtue of its excellent construction and strong capability to withstand high temperatures and pressures. Made of a stack of tubes encased in a shell, these heat exchangers offer efficient heat exchange between two fluids and can be applied to process heavy industry, such as oil and gas production, power generations, petrochemicals, and so on. Being both robust and able to better tolerate extreme operational conditions, they are the option to allow such large-scale applications.

Air-Cooled Heat Exchanger: Air-cooled heat exchangers (ACHEs) have recently become very popular owing to non-polluting and water-conserving characteristics. These coolers exploit ambient air to cool liquids, thus dispensing with the use of water as a means for cooling. ACHEs are widely implemented in such industries as oil and gas, power generation, and petrochemicals, particularly in areas with water shortages. Due to its low operating cost and environmental impact, it can be considered as a green alternative to the aqueous cooling systems.

These exchangers are for very specific uses which need them to be small, have excellent corrosion resistance, and be able to use very viscous fluids. Welded and brazed exchangers are widely employed in the chemical and pharmaceutical sector, while spiral exchangers are more appreciated for sludge treatment or for applications with the possibility of fouling. Such products offer custom solutions to the specific industrial issues and, in consequence, they are contributing to the innovative design of heat transfer technologies.

Material Analysis

Metal: The metal segment has dominated the market in 2024. Metal heat exchangers (commonly produced by stainless steel, copper and aluminum) are the sales leaders, due to its high thermal conductivity, strength and corrosion resistance. Stainless steel is very commonly employed because of its general utility, its resistance to high temperature, and its compliance in a hygienic environment (food and pharmaceuticals). Copper exhibits high thermal transport efficiency, which is makes it suitable for the cooling systems of HVACs and electronic devices, whereas aluminum is highly valued for automobile and aerospace applications due to its low weight.

Alloys: Alloy heat exchangers are being adopted to a greater extent due to their enhanced strength, corrosion resistance, and performance at extreme conditions. Titanium alloys, nickel and Inconel alloys are widely used for chemical processing, marine and power generation applications. Titanium, for instance, has excellent seawater corrosion properties, and is thus attractive in the context of desalination plants. Nickel-based alloys are all around us, and are suitable for high-temperature-high-pressure applications, which at the same time will assure the reliability of key applications.

Others: The "Others" group consists of non-metallic materials such as graphite, ceramics and composites, many of which are becoming increasingly relevant in niche applications where resistance to very aggressive chemical substances is necessary. Graphite heat exchangers are widely used in chemical industry due to their excellent thermal conductivity and corrosion resistance. Due to good resistance to the working conditions of high temperature, ceramics have been applied satisfactorily in high-temperature work, e.g., incineration, and gas turbine.

End-Use Analysis

Chemical & Petrochemical: The chemical and petrochemical segment has dominated the market in 2024. In the chemical and petrochemical industry, the role of heat exchangers is of great importance since various processes need fine temperature control including distillation, condensation and reaction cooling. Heat exchangers play a crucial role in the performance and safety of operations with corrosive chemicals and hot fluids. Materials, for example, stainless steel, titanium, and alloys are favoured for their corrosion resistance and robustness.

Oil & Gas: The Oil & Gas segment is expected to witness strong growth over the forecast period.

Heat Exchanger Market Revenue Share, By End-Use, 2024 (%)

HVAC & Refrigeration: Heat exchangers are the core of HVAC, refrigeration, and other temperature control systems and have been important for providing good heating, cooling, and ventilation in residential, commercial, and industrial buildings. These systems are made on the basis of miniaturized, compact, and extremely efficient heat exchangers through which it is possible to obtain an optimum indoor climate using a small amount of energy. Plate, finned-tube- and air-cooled heat exchangers are widely exploited because of their small dimension and good efficiency.

Power Generation: Power plants (fossil, nuclear, and renewable power plants) make use of heat exchangers to extract the ultimate amount of energy and cooling. Shell-and-tube heat exchangers are employed in thermal and nuclear power plants for controlling condensate condensation and sensible heat recovery and in the smart exploitation of renewable energies (geothermal and solar thermal steam generators), and in the case of plate heat exchangers, losses are minimized. With the increasing demand for energy and the increasing promotion of clean power generation techniques, it is necessary both for the stability and high performance of heat exchangers.

Food & Beverage: The food and beverage industry employs heat exchangers in the pasteurization, sterilization, and chilled process stage and as a result guarantees safe and quality products. These plate heat exchangers are widely used in this field because of the hygienic design and easy cleanability that fully conform to the strict food hygiene conditions. Applications range from dairy products and juices through to processed foods and brewing industries, etc.

Pulp & Paper: Heat exchangers are needed in the pulp and paper industry for, for example, pulping (hydrolysis), bleaching and paper drying applications, etc. Those stages are performed at high temperature and in a corrosive environment, and therefore corrosion-resistant and corrosion-pened heat exchangers are required. Heat exchangers, shell-and-tube and spiral, are commonly used as it allows to work effectively at high fluid flow rates.

Others: For "Others," there are highly narrow specializations (pharmaceuticals, textiles, marine technologies) where, by definition, heat exchangers occupy a small niche. In the pharmaceutical domain, heat exchangers are employed to regulate temperature precisely for drug formulation and sterilization. They are also applied to textiles for coloration and drying as well as to marine applications for seawater cooling and energy recovery.
