The dimensions of a standard radiator are as shown in the drawing. The variable dimensions are

  • Centre distance 'CC'
  • Total length 'L' depending on the number of sections
  • Header pipe extension 'a'

These dimensions are to be determined by the transformer manufacturer based on the design. Generally, centre distance 'CC' increases in steps of 100 mm from a minimum of 300 mm to a maximum of 500 mm. Radiators in higher lengths can also be manufactured for specific requirements.
