Semi-Welded Plate Heat Exchanger

High Performance, Maximum Durability

Semi-welded heat exchangers are special types of heat exchangers used to provide heat transfer and combine the characteristics of both welded and plate heat exchangers. These types of heat exchangers are generally used in industrial applications and in systems requiring high performance.

Plate packs are formed by laser welding two separate plates flat on top of each other. This heat exchanger model, which is assembled by placing a gasket between each plate package, provides the advantages of the traditional type plate gasketed heat exchanger and can also be easily used in applications where sealing plays a major role.

 

Description

What is a Semi-Welded Heat Exchanger?

Semi-welded plate heat exchangers consist of plate packages formed by joining two separate plates by laser welding. This structure provides both resistance to high-pressure fluids and flexible use with gaskets placed between the plates. It combines energy efficiency and safety, especially in industrial plants and systems requiring high performance.

Working Principle

In semi-welded plate heat exchangers, each plate package is formed by laser welding and sealing is ensured. The fluids move in opposite directions between the plate surfaces, realizing maximum heat transfer. Special channels on the plates increase energy efficiency by increasing the turbulence of the fluid. The use of gaskets prevents mixing of fluids and offers easy maintenance and flexibility.

Advantages

  • High Heat Transfer: Effective heat transfer with optimized plate design.
  • High Pressure Resistance: High pressure resistance thanks to laser welded construction.
