Cast aluminum electric heater is a kind of electric heater with tubular electric heating element as heating element and die-casting with high-quality casting material. Its use temperature is generally between 150-450 degrees Celsius, which can be widely used in plastic machinery and die. , cable machinery, chemicals, rubber, petroleum and other equipment. The cast aluminum heater features long life, good thermal insulation performance, strong mechanical properties, corrosion resistance and magnetic field resistance. The explosion-proof heater explosion-proof mark is ExdIIBT4 ExDIIBT6 ExdeIICT6, etc. The cast aluminum electric heater is a high-efficiency heat-segmented uniform heater with excellent thermal conductivity of metal alloy, ensuring uniform temperature of the hot surface, eliminating hot spots and cold of equipment. point. It has the advantages of long life, good thermal insulation performance, strong mechanical properties, corrosion resistance and magnetic field resistance. The external heat dissipating surface is increased by the heat preservation device, and the inner heat dissipating surface is sintered with infrared rays, thereby saving 35% of electricity consumption.
