SHELL & TUBE

SHELL & TUBE HEAT EXCHANGER DNA heat exchangers represent next step in the evolution of tubular heat exchangers. They deliver significant benefits in the areas DNA achieves significantly higher heat transfer rates comparing to standard solution. The design of the unit allows for more efficient operation in high volume applications (e.g. flue gas, hot air, low pressure steam). The construction of the DNA heat exchanger enables to obtain smaller and lighter device. At the same time, the exchanger retains all the advantages of the shell & tube heat exchanger, especially its high mechanical...

DNA TUBE BUNDLE FEATURES Effective turbulent vortex flow increases heat transfer coefficient up to double values due to helical tube geometry. DNA HEAT EXCHANGER ADVANTAGES EFFECTIVE HEAT TRANSFER AREA TURBULENT FLOW Effective heat transfer area with more homogeneous distribution of flow and velocity field. LOW PRESSURE DROP 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 CONSTRUCTIO
