Immersion heaters for light metals

 

Access the most efficient and environmentally friendly heating solutions for aluminum alloys and zinc alloys.

Aluminium ultra-compact immersion heating for die casting holding furnaces

    To ensure a precise steady temperature control, or to achieve a quick dynamic reheating, Atherm Immersion Heating technology provides you the most efficient solution among all alternative heating technologies for molten aluminium.

    Thanks to direct heating of the metal, with just the required amount of heat, you minimize the energy losses and avoid metal damages and metal losses due to oxydes, corumdun, drosses…

    Thus, you also save productive time, avoiding time consuming and tricky cleaning operation of resistances.
    This technology is suitable for high pressure die casting, gravity die casting and low pressure die casting, and as well for degassing, filtration unit or transport ladle re-heating.

    ENERGY SAVINGS

    Atherm’s clients have reported 20%, 30% and even 40% energy savings using our immersion heaters in diverse settings.

    Decarbonization

    As electrical devices, immersion heaters are a fully decarbonized heat source, generating no CO2 during the industrial process.

    SAVE PRODUCTION TIME

    Atherm’s clients regularly report high metal purity, exceptional quality of cast parts, and reduced metal oxidation.

    Short maintenance times

    Targeted heating and precise temperature regulation help to optimize maintenance work. Cleaning depends on the quality of the metal and can even be unnecessary with high-quality baths. Atherm’s

    QUICK REHEATING

    The light metal industry generally needs bath temperatures to rise rapidly. Atherm’s range of conductive immersion heaters was designed to generate very high surface power densities, enabling our technology to transfer very high power levels to the baths, for rapid reheating after maintenance or refilling.

    PREHEATING

    The new Supratherm Dual immersion heater line offers an additional advantage of heating the air (when using the long heating unit), as well as the metal (with the short heating unit), enabling it to also be used to preheat the furnaces. This feature is also helpful when the level of the metal bath is too low since, when the heating unit is partially immersed and the power set appropriately, this heater is still able to work and heat.
