Heat exchanger types

One of our customers’ major concerns is deciding between various types of heat exchangers. And it’s not hard to see why all the fuss. The selection of the proper type of heat exchanger is critical for the overall reliability, energy efficiency, and output of the entire application. Selecting the wrong type can lead to inferior performance, operability issues, or even equipment failure.

So how can you select the type of heat exchanger that is best suited for your application? The following categorization of heat exchanger may help you understand the working principle of different heat exchangers, their advantages and limitations and discover the applications they are suited for.

Whether you are looking for graphite heat exchanger or you are interested in brazed heat exchangers, our team of experts will provide you the information you need in order to make the right decision.

Graphite heat exchanger

Graphite is a widely used material in heat exchangers due to its great refractory and mechanical properties. Offering better corrosion resistance than most types of heat exchangers, the graphite heat exchanger is used in a wide range of chemical applications, such as food and beverage, petrochemical, chemical processing, metal finishing, and more.

Key benefits:

  • The graphite heat exchanger is highly thermal efficient;
  • Flexible and compact design;
  • Rapid replacement of damaged block due to the compact design;
  • Corrosive resistance.


Brazed heat exchangers

Brazed plate heat exchangers accommodate a set of plates that are brazed together, but without the gasket and frame parts. The stainless steel composition with copper brazing make brazed heat exchangers resistant to high temperatures and corrosion.  Compact and lighter than regular plate and frame heat exchangers, they can complete the thermal exchange process quicker.

Key benefits:

  • The compact design makes them perfect for tight spaces;
  • Brazed heat exchangers offer maximum performance at low installation and maintenance costs;
  • Easy to clean and maintain;
  • Environmentally friendly.


Radiator Heat Exchanger

A radiator is a heat exchanger that transfers thermal energy from one medium to another. In a radiator heat exchanger design air is blown within tubes, picking up heat from the stream on the tube-side, which is cooled. The resulting hot air is dispersed into the atmosphere or is used to heat buildings or other equipment.

Key benefits:

  • Environmentally friendly: radiator heat exchangers don’t require water;
  • Flexible design;
  • Prevention of thermal and chemical pollution of cooling fluids;
  • Easy installation;
  • Low maintenance costs.



Shell & Tube heat exchanger

Shell and tube heat exchangers have been used for more than 150 years in almost every industrial application, including chemical process industries. Probably the best known and understood heat exchanger, the shell and tube design is widely popular, mostly for its versatility in terms of types of services.

Key benefits

  • Able to meet process requirements in almost every industry or application;
  • Highly efficient and reliable;
  • Built from solid materials, they can handle a wide range of pressures and temperature requirements;
  • Easy maintenance.


Plate heat exchangers

Unlike shell and tube, a plate heat exchanger uses metal plates to transfer heat between two fluids. This gives the design a major advantage in that the overall heat transfer coefficient is higher than in a traditional shell and tube heater.

Key benefits

  • The compact configuration allows for the same thermal efficiency as a shell and tube heat exchanger, but on a smaller area;
  • High thermal efficiency;
  • Easy maintenance: plate can easily be removed to be cleaned or repaired.
