Aluguard is a special purpose thermowell with refractory surface which resists erosion and fast eating up-off by molten Aluminium.The refractory material along with special intrinsic packing used which provides high thermal resistance. Further no additional coating is required to prolong working life, the tip of Aluguard is constructedwith special arrangement which provides good protection from high heat during dipping in molten aluminium to provide better life to sensor and thermowell.
