Plate heat exchangers are devices used to transfer heat between two fluids through a series of metal plates. Each plate typically features a series of corrugations to increase the surface area available for heat transfer. The two fluids, each flowing on opposite sides of the plates, are kept separate to prevent mixing.

The purpose of plate heat exchangers is to efficiently transfer heat from one fluid to another. They are widely used in various industrial processes and HVAC systems for heating, cooling, evaporation, and condensation. Plate heat exchangers offer several advantages, including compact size, high heat transfer efficiency, and easy maintenance.

These heat exchangers are particularly well-suited for applications where there is a need to exchange heat between fluids without direct contact. The design of plate heat exchangers allows for a high rate of heat transfer due to the large surface area provided by the plates. They are versatile, cost-effective, and offer flexibility in terms of capacity and thermal performance.

Overall, plate heat exchangers play a crucial role in optimizing energy usage, enhancing process efficiency, and maintaining consistent temperatures in various industrial and commercial settings.



Brazed plate Heat ExchangersBrazed Plate Heat Exchangers are small, light, and compact.  It does not need gaskets.   Instead, it is brazed together using cooper to give a strong, compact construction.

Plate heat exchangers are devices used to transfer heat between two or more fluids, without allowing them to mix.  They are composed of a stack of corrugated metal plates, sealed with gaskets, and held together within a frame.  The fluids flow in separate channels formed by the plates.

The heat transfer surface area can be increased or decreased by adding or removing plates, making plate heat exchangers quite versatile.  These exchangers are popular due to their high heat transfer efficiency, compact size, and ease of maintenance.

Different types of metals used in plate heat exchangers include stainless steel, titanium, and various nickel alloys.  Stainless steel is commonly used for general applications, whereas titanium offers exceptional corrosion resistance, making it suitable for highly corrosive environments.  Nickel alloys are used for specific high-temperature applications.

In terms of connections, there are several types:

Gasketed Plate Heat Exchangers:  These are sealed using gaskets and are suitable for most applications.  They allow for easy disassembly and flexibility in plate arrangement.

Brazed Plate Heat Exchangers:  In this type, the plates are brazed together, eliminating the need for gaskets. This provides higher pressure and temperature resistance, making them suitable for more demanding applications.

Welded Plate Heat Exchangers:  These use welded channels to join the plates, creating a rugged, compact design.  They are often used in applications where hygiene and long-term reliability are crucial.

Each type of connection and metal used offers unique benefits and considerations based on the specific needs of the application.

Brazed plate heat exchangers typically have flanged or threaded connection ends.  These connection ends allow for easy integration into the overall fluid system.  Flanged connection ends are commonly used for larger, industrial applications, providing a secure and robust attachment, while threaded connection ends are often employed in smaller-scale systems or where accessibility is limited.  Finally, these connection ends enable convenient installation and maintenance of the brazed plate heat exchangers within a variety of fluid handling systems.


Also, Our BPHEs are extremely compact compared with other technologies. The footprint can be as little as one-tenth that of a shell & tube heat exchanger or half that of a gasket PHE.  Brazed plate heat exchangers have a compact design compared to traditional heat exchangers, allowing for a high surface area-to-volume ratio.  Furthermore, this compactness promotes efficient heat transfer between the fluid streams, reducing energy losses and optimizing performance.


When gaskets or supporting equipment are not required, about 95% of the material is used to transfer heat.  The highly turbulent flow also enables you to use small temperature differences efficiently.

Excellent Heat Transfer

The corrugated plates in brazed plate heat exchangers create turbulent flow patterns, enhancing heat transfer efficiency. These plates maximize the contact area between the fluids, facilitating rapid and efficient heat exchange.


In addition, the robust construction requires no gaskets, eliminating their risk of leaking. This means stable thermal and hydraulic performance, with minimal maintenance and operational downtime.

Leak-Free Design

The brazing process used in manufacturing brazed plate heat exchangers creates a robust and leak-free seal between the plates. This eliminates the risk of cross-contamination between the fluid streams, ensuring optimal heat transfer efficiency.

Low Hold-Up Volume

Brazed plate heat exchangers have minimal hold-up volume, meaning that there is less fluid stagnant within the exchanger. Additionally, this results in reduced energy wastage and faster response times in heating or cooling processes.


Also, the compact size uses space efficiently and makes system design more flexible.

Brazed Plate Heat Exchangers are Cost-effective

Also, you will save on energy, maintenance, spare parts, and installation.  Also, the life-cycle cost over 15-20 years can often be half that of a corresponding gasket solution.


In addition, our BPHEs are normally self-cleaning, thanks to highly turbulent flows.  Moreover, in applications with a high risk of fouling or scaling, cleaning in Place is easy without disassembly.


Also, by combining plate design, materials, and connections from standard components, we keep lead times short while still maximizing output in your specific application.

Overall, the combination of compact design, excellent heat transfer capabilities, high thermal conductivity, low hold-up volume, and leak-free construction makes brazed plate heat exchangers highly efficient for a wide range of heating, cooling, and refrigeration applications, leading to energy savings and improved process performance.
