LIndain Engineering has been a supplier of licensed specialty tube supports for tubular exchangers for nearly twenty years for critical services in solar and nuclear heat transfer applications. The recently awarded US and EU patents for AXI-GRID tube support baffles, facilitate disc and donut style flow modulation which has been demonstrated to provide maximum thermodynamic heat transfer efficiency. The AXI-GRID baffles provide a robust, lightweight, tube support structure impervious to tube vibration, compatible with all tube OD and pitch design combinations to maintain smallest equipment envelope for required heat transfer area
