Graphite Heat Exchanger

Graphite Heat Exchanger


Graphite coolers or heat exchangers consist of a blocks drilled on two sides . One side of these blocks contains the fluid that must be either heated or cooled. The second side contains coolant or the heating medium so that it can either provide the heat required or absorb the heat from the process media through high thermal conducive Graphite blocks. Block type heat exchangers are typically used for high-pressure This is because the block type heat exchangers are robust due to their shape and strength.

There are several thermal design features that are to be taken into account when selecting coolers or heat exchangers like:


  • Horizontal designs
  • Vertical designs
  • Capable of handling heating utility medium as steam, heat transfer oil or other mediums.
  • Capable of handling cooling medium as water or even brine.

    • Multi-Stage Steam Jet Ejectors:

    Staging of ejectors becomes necessary for economical operation as the absolute suction pressure decreases. Based upon the use of auxiliary equipment, two and three-stage ejectors can either be condensing or non-condensing types.

    Salient Features

    • Cubical block type, simple robust and easy to install tough construction
    • Consists of entry chamber, multiple process blocks and exit chamber all made of impervious graphite.
    • Simple design and easy dismantling as compared to circular blocks.
    • Resistance to Thermal Shock.
    • Multiple passes can be provided on service as well as process sides.
    • Simple robust and easy to install tough construction.
    • Flexibility of adding more blocks to increase heat transfer area.
    • For connection nozzles, metal plate apply compressive load on graphite, as graphite has high compressive strength thus prevents connection nipples from easy breakages.
    • Short channel lengths increases turbulence as a result avoids frequent deposits or fouling as compared to shell & tube type heat exchanges of same dimensions, cubical block type heat exchanger provides 2 to 5 times more heat transfer.
    • Can be provided vertically in case of falling film absorbers and horizontal when reflux system are to be provided in condensers.
    • Working condition full vacuum to 5kg / cm2 pressure.
    • For client's benefit, we also offer erection and commissioning services.
