shell and tube heat exchanger

The principle is the same as tube heat exchanger, but corrugated plates are used instead of tube, plates are welded by laser or TIC and assemble into cylindrical shell, thus makes the heat transfer efficiency of fully welded PHE is much higher than tube heat exchanger.
Features
? Without gasket;
? Maximum k- value;
? Safer operation, avoid leakage;
? Heat-resistant, the working temperature can be 250?;
? Less liquid hold-up;
? Easy maintenance;
? Saving space ( equivalent 30% space of tube heat exchanger ).
