CSN® flange heater type 96F

CSN® electric flange heaters are designed for the electrical heating of liquid and gaseous, flowing and stagnant media.


Our electric flange heaters are used under demanding conditions to heat liquids and gases for industrial processes. With our high-quality CSN® tubular (∅ 8.5 to 16 mm) or cartridge heaters (∅ up to 52 mm) and a customised surface load for every process, we offer a long service life and high efficiency. We only use high-alloy stainless steels.

Product advantages

  • High power density possible
  • Manufactured in accordance with the Pressure Equipment Directive 2014/68/EU
  • Precise temperature monitoring
  • High operational safety and reliability
  • Use of CSN® high-compression tubular or cartridge heaters in flanges up to DN 1000
