Abstract: Energy saving is major matter in our global world, and heat exchanger is very useful for energy saving. Of course heat exchanger is most significant component for chemical reaction, distillation, dissolution, crystallization, fermentation etc. So the correct selection of heat exchanger is important in these process industries. Spiral Heat Exchangers are known as excellent heat exchanger because of compact structure and high heat transfer efficiency. The flow of the two fluids is counter-current, which makes it possible to have a close temperature approach between the two medias being treated in the heat exchanger.A large variety of fluids can be suitable for a spiral heat exchanger solution e.g. fouling liquids containing solids and fibres, waste water, slurries, mixtures with inert gases, cooling and heat recovery, vapour/liquid condenser and vacuum condenser with inert gases.
