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).
Shell & tube heat exchangers consist of a shell and a tube bundle inside. A tube bundle can have a form of a coil (like in JAD, S and H) or straight tubes (like in B, TI, EVO, REV and P). In most cases hot medium goes in tubes and cold medium in a shell. Shell & tube heat exchangers are welded and manufactured using stainless steel throughout which prevents risk of a leak and makes them resistant to corrosion. Thanks to many types and sizes shell & tube heat exchangers are ideal solutions for industrial purposes as well as in domestic heating systems.
Effective turbulent and swirl flow increases heat transfer coefficient up to double values due to helical tube geometry
More effective heat transfer area with homogeneous distribution of flow and velocity field.
Flexible tube bundle, low pressure drop, no dead spots, baffle-free, no need of shell compensator and elimination of vibration due to the multiple contact points along the tube bundle.
Large heat transfer area contained in compact construction - ideal for high volume media.
