Cast aluminum electric heater has long life and good heat preservation performance

The cast aluminum electric heater is an electric heater with a tubular electric heating element as the heating body and a high-quality aluminum alloy material as the outer shell. Its operating temperature is generally between 150 and 450 degrees Celsius and can be widely used in plastic machinery and mold heads , Cable machinery, chemical industry, rubber, petroleum and other equipment. The cast aluminum heater has the advantages of long life, good thermal insulation performance, strong mechanical performance, corrosion resistance, and anti-magnetic field. The explosion-proof mark of the explosion-proof heater is ExdⅡBT4 ExDⅡBT6 ExdeⅡCT6, etc. The cast aluminum electric heater is a kind of heater with high efficiency and uniform heat distribution. It is a metal alloy with excellent thermal conductivity, which ensures uniform temperature of the hot surface and eliminates hot spots and cold point. It has the advantages of long life, good thermal insulation performance, strong mechanical properties, corrosion resistance, and anti-magnetic field. Add heat preservation devices to the outer heat dissipation surface, and sinter infrared rays on the inner heat dissipation surface, which can save 35% of electricity consumption.
1) The working voltage shall not exceed 10% of the rated value;
2) The wiring part is placed outside the heating layer and insulation layer, and the shell should be effectively grounded;
3) The cast aluminum heater should be placed in a dry place. If the insulation resistance is lower than 1MΩ due to long-term storage, it can be baked in an oven at about 200 degrees Celsius for 5-6 hours to return to normal.
