Samhwa has developed a new design (patented) of heat exchanger that is generating considerable interest among polymer producers. It uses helical mixing elements as before, but they are inserted into coils rather than tubes.

The coil/mixer assemblies are arranged in a vessel similarly to a shell and tube heat exchangers design. However, a key difference is that the heating or cooling fluid flows through the coils while the product flows in the open space previously filled by the heat/cooling agent. The result is a high heat transfer unit that requires much less flange wall thickness for a given pressure. Weight is substantially reduced, thereby reducing unit and installation costs.

Lower pressure drop than other static mixer heat exchangers Weight reduced from half to two thirds Higher heat transfer Less cost Stronger than normal hell and tube type heat exchangers
