    Air blast coolers

    Air blast cooler designed and manufactured by Sterling Thermal Technology

    Also known as a fin fan cooler, air blast coolers harness ambient air to cool process fluids like lubricants. For industrial cooling, we design all sizes, from compact units for ship stabilisers to coolers exceeding six metres in length. Find out more on our air blast cooler page.

    Air coolers

    Air coolers contribute to the efficiency of processes involving air by utilising various cooling mechanisms, often including chilled water. These coolers help maintain the air at the precise temperature required. Find out more on our industrial air coolers page.

    Air preheaters

    Photo of an air preheater using NEL fin technology, designed and manufactured by Sterling Thermal TechnologyAir preheaters use energy from the outgoing process stream (usually hot flue gas or exhaust gases) and heat the incoming air. This exchange optimises the system’s thermal conditions and improves overall performance, efficiency, and energy conservation. The goal is to recover heat that would otherwise be wasted and use it to enhance the efficiency of the overall system. Find out more on our air preheaters page.

    Ancillary heat exchangers

    These heat exchangers are designed to complement primary heat exchange units, providing additional thermal regulation or specialised functions within a system. Contact us and find out how we can help you with ancillary heat exchangers.

    Condensers

    Industrial condensers cool gaseous process streams below their dew points, converting most of the gas into liquid form by extracting heat. In steam condensers/surface condensers, exhaust steam from a turbine can be reused in liquid form, which often provides an efficient way to recover and reuse heat in industrial processes. Find out more on our condensers page.

    Process air heaters

    Process air heaters elevate air temperature for industrial applications like drying and heating. They use heating elements to raise air temperature to desired levels with precise control, which is crucial for efficiency in processes. Contact us and find out how we can help you with process air heaters.

    Economisers

    Economisers capture heat from boiler or gaseous heat source emissions. They then use it to pre-heat streams like feed water or combustion air, making the process more economical by recycling heat that would otherwise be lost. Find out more on our economisers page.

    Shell and tube heat exchangers

Our bespoke shell and tube heat exchangers are suitable for large industrial-scale applications to serve various purposes. Find out more on our shell and tube page.

    Steam air heaters

    Steam air heaters heat air and liquids using steam. They are crucial in industries prioritising reliability and durability, such as food production, pharmaceuticals, and high-value industrial manufacturing. Find out more on our steam air heaters page.

    How an industrial heat exchanger works

    The process begins with the fluids entering the heat exchanger through separate pathways, often called the hot and cold sides. Once inside the heat exchanger, the fluids remain separated by walls but come into proximity, allowing heat to transfer between them.

    These fluids can be gases, liquids, or a combination of both, depending on the specific application. For example, in an industrial chemical manufacturing process, one fluid might be a heated solvent while the other is a cool solvent or reactant solution.

    The effectiveness of a heat exchanger depends on several factors, including the design and geometry of its heat transfer surfaces, the flow rates and temperatures of the fluids involved, and the thermal properties of the materials used in its construction.


    Why choose Sterling TT 

    To ensure our heat exchangers offer significant benefits, we use our expertise and experience to design and manufacture them to your specific requirements.

    Customisation

    Many industrial applications require custom-designed heat exchangers to meet specific requirements. We have the in-house capability to design and produce tailored solutions.

    Material selection
    We choose the most suitable material, which is critical because your heat exchanger must withstand corrosive and/or erosive environments, high pressures, and temperature extremes. Material selection affects the durability and performance of the heat exchanger.
    Design complexity
    Heat exchanger design can be complex, especially for custom or specialised applications. Therefore, we consider factors like flow rates, temperature differentials, and fluid properties to optimise performance.
    Sizing

    Cost considerations

    We’ll balance performance with cost-effectiveness. We strive to find ways to minimise your ownership costs while meeting your requirements.

    Safety standards

    Heat exchangers in industrial applications must adhere to safety standards and regulations to protect workers and the environment. We’ll ensure compliance with standards, including ASME VIII or ASME U stamp. 



    Why heat exchangers are crucial

    Energy efficiency

    Heat exchangers can help improve your energy efficiency by transferring waste thermal energy to the incoming flow, reducing the overall energy consumption in industrial processes.

    Temperature control

    Heat exchangers are essential for maintaining precise temperature control in industrial processes. They can heat or cool process fluids as needed, ensuring the desired temperature is consistently maintained.

    Waste Heat Recovery (WHR) 

    Heat exchangers are used to recover waste heat from industrial processes. This recovered heat can be reused to preheat incoming fluids or other purposes, reducing energy costs and environmental impact.

    Process optimisation

    Heat exchangers optimise various processes by controlling temperature gradients, which is crucial in industries such as chemical manufacturing or food processing.
