General informations

hese resistances can be used for water heaters, open water heaters and boilers. The armoured electric resistances for water heaters are produced to operate immersed in water with a relative limited maximum temperature, with a high possibility of corrosion if used in hard or chlorinated waters. Such corrosion can be prevented by using special magnesium anodes. Manufactured in compliance with European and International safety standards they guarantee adequate functionality, heat yield, duration and safety. The use of resistances with a maximum surface load of 9 W/cm2 is recommended in order to contain the noise level during the heating phase.

Technical characteristics

  • Rated voltage: 230 V single phase (on request resistance from 110V to 240V are avaiable)
  • Rated power: from 1200W to 3000W
  • Frequency: 50 Hz
  • Connections: ISO 228/110 M 1” ¼ filetto Gas – Flange Ø 48mm
  • Flange material: Brass EN 12165 CW 617 N
  • Diameter of resistance tube: 8 mm
  • Material of resistance tube: copper
  • Electric connection: fasten standard female
  • Surface load range: on request
  • Thermostat probe door: L = 275 mm with rigid copper rod, bottom of scale 70-80°C single or double safety device in compliance with standard EN 607304
  • On request with insert for anode
