Electric resistances

Armour-Clad Electric Resistances for Water Heaters
These resistances can be used for: Pressurised water heaters, open water heaters, pressurised or free boilers.
The amour-clad electric resistances for water heaters are produced to operate immersed in water at a relatively 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 an 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.
