The heat-transfer plates are welded together in these PHEs, eliminating the requirement for an external gasket. Gasketed plate heat exchangers are ideal for a wide range of applications, although they have temperature and pressure limitations, as well as the danger of gasket failures and/or penetration. Semi-welded plate heat exchangers are subject to the same dangers. This risk of gasket failure is reduced with fully welded plate heat exchangers.
The heat transfer portion is formed by stacking press-moulded heat transfer plates on top of each other, with side cover plates affixed to the four directions of this plate pack. To execute heat exchange, high-temperature and low-temperature fluids flow in a cross-flow via the heat transfer section. Baffles can be placed according to the design circumstances to create a multi-pass design for the best results. Fully welded PHE can flexibly accommodate scenarios with substantial differences in fluid flow rates or tiny flow rates, and the nozzle bore can be freely selected to match the operating requirements.
Applications of Fully Welded Plate Heat Exchangers:
- Aerospace Sector
- Environment Sector
- Petrochemical Sector
- Pharmaceutical Sector
- Steel Sector
- Sugar Refining Sector
