Evaporators are radiators formed by grouping finned or bare, straight or oval tubes. Evaporators are generally used in the energy, maritime, petro-chemical, iron and steel sectors to evaporate the fluids in the pipes by using the energy of waste gases. Evaporators are generally manufactured as welded since they are exposed to high pressure and temperature. They can be manufactured in various shapes and sizes according to project and process requirements, and from various materials based on service life and durability.
