Alfa Laval IndustrialLine T20 W Gasketed Plate-and-Frame Heat Exchanger

Alfa Laval Industrial semi-welded line is used when gaskets are not suitable for one of the process media. The semi-welded line can also withstand a higher design pressure compared to fully gasketed plate-and-frame heat exchangers. Suitable for a wide range applications, this model is available with a large selection of plate and gasket types.
