  • a radiator element can be used alone or combined with other similar elements to form batteries of radiator elements.
  • radiator elements There are various types of radiator elements.
  • fluid circulation radiator elements are widely used, e.g. of the column type, plate type, etc., having a hollow body inside which a heating fluid circulates.
  • radiator elements are also common to provide the radiator elements with radiant plates and fins in order to increase the heat exchange surface with the environment in which they operate.
  • radiator element having an essentially tubular body, provided with an inner water chamber and hydraulic connections arranged at the opposite ends of the element.
