Aluminium Immersion Heater

Immersion heaters for molten non-ferrous heating and handling with 12 months warranty against electrical defects!

Aluminium immersion heater for non-ferrous melts is directly immersed into liquid molten aluminium up to 800 C. Made of a proprietary metal  resistance inserted into a high performance insulator conducting heat, the parts are put into a special grade Sialon sheath directly immersed into the liquid metal.
