What is Semi-weld PHE?
The Semi-weld Plate heat exchanger plates are welded by laser. The laster welding means that metal is melted power laser. The charge is protected by irert gas Additional welding material is not required.
Applications
Chemicals
Energy and Utilities
Food& Beverages
HVAC&Refrigeration
Marine and Transportation
Mining
Pulp andPaper
Steel
Water and Waste treatment
Benefits
High heat transfer efficiency: due to their large surface area and turbulent flow paths.
Low riskof leakage: The fully welded channels reduce the risk of leakage and cross-contamination between different fluids.
Easy maintenance: Semi-welded plate heat exchanger can be easily disassembled and cleaned, allowing for easy maintenance and reduced downtime.
Versatile: Semi-welded plate heat exchangers can be used in wide range of applications, including refrigeration and cooling, heating, and HVAC systems.

How it works?
The heat transfer area of a gasketed plate-and-frame heat exchanger consists of a series of corrugated plates, assembled between the frame and pressure plates, which retain the design pressure. Fluids normally run counter-currently through the heat exchanger in order to High Thermal Performance and Close Temperature approach.
The sealing between the plates on the Industrial semi-welded line alternates between laser welds and gaskets. The laser welded channel allows use of fluids that are not compatible with normal gaskets and also allows for higher design pressure than fully gasketed plate-and-frame heat exchangers.
Semi-welded Plate Heat Exchanger is available with various pressing depths and angles of the chevron pattern and various shapes of the corrugation which are carefully designed and calculated to achieve optimal performance. The Counter Flow and the chocolate pattern distribution area are two design features available that ensure fluids are evenly distributed across the entire plate. The result is that the entire heat transfer surface is fully utilized and stagnant zones that can result in fouling are avoided.
High flow turbulence between plates results in higher heat transfer; however, the consequence is pressure drop. Our thermal design engineers will help you design and select the model and configuration that is suitable for your application needs while delivering maximum thermal performance and minimizing pressure drop.
