DNA SHELL & COIL 7 HEAT EXCHANGER jMtT' y y

4 DNA features DNA heat exchangers represent next step in the evolution of tubular heat exchangers. They deliver significant benefits in the areas of hydraulics and heat transfer while maintaining the features and benefits of traditional shell & tube design. DNA achieves significantly higher heat transfer rates comparing to standard solution. The arrangement of the heat exchange surface in the shell side allows for more efficient operation in high volume applications (e.g. flue gas, hot air, low pressure steam). Effective turbulent and swirl flow increases heat transfer coefficient up to...
