Filling machine for monotube heating elements

CSM MACHINERY, in addition to filling machines for double-side tubular heating elements, produces state-of-the-art machine for filling special heating elements, i.e. cartridge and monotube ones.

A monotube heating element is composed by two wound wires arranged side by side within a steel tube and isolated with magnesium oxide (MgO). 

The monotube filling machine is designed specifically for the filling of monotube heating elements that are characterized by a closed extremity and an open end in which two or more terminal pins are mounted.

The advantages of the filling machine for monotube heating elements designed by CSM MACHINERY are:

  • Reduction of production times.
  • Simultaneous filling of all stations.
  • Increased filling speed through the precision and efficiency of automatic filling technology.
  • Improved compaction of magnesium oxide (MgO) by means of electromechanical vibration system. 
  • Scrap reduction thanks to a system which control the MgO flow and stops it when the device is closed. 
  • Ease of use thanks to the installation of a simple and intuitive operator interface.
  • Simultaneous manual loading of all tubes.
  • Motorized set up time when changing the length of the tube to be filled. 
  • Possibility to fill heating elements with two terminals at both ends (like a traditional heating element, but with two coils).
  • Ease of installation for the end customer. 

All the advantages of our monotube filling machine allow to offer more efficient, longer-lasting and cheaper heating elements than those produced by filling machines for double-side heating elements.
