CSN® tubular heating elements

Heavy-duty and highly compressed - our tubular heating element guarantees efficient heat even in demanding applications.


Tubular heating elements, also known as tubular heating elements, act as ohmic resistors and are characterised by their versatility. When used properly, they have a long service life. They are used to heat gases, liquids and solids, with optimised shaping playing a decisive role in their efficiency.

Product advantages

  • Design with optimised surface load guarantees long service life
  • Direct heating of water, oils and other liquid media, gaseous media
  • Good bendability
  • High efficiency
  • High heat transfer / conductivity
  • Customisable design possible - power / voltage / materials / shapes
