Cast aluminum electric heater is a heater with high efficiency and uniform heat distribution. The metal alloy with excellent thermal conductivity ensures uniform hot surface temperature, eliminating hot spots and cold spots in the equipment. It has the advantages of long life, good thermal insulation performance, strong mechanical properties, corrosion resistance, and magnetic field resistance. Adding insulation devices to the external heat dissipation surface and sintering infrared rays on the internal heat dissipation surface can save 35% of electricity.
1) The working voltage shall not exceed 10% of the rated value;
2) The wiring part should be placed outside the heating layer and insulation layer, and the shell should be effectively grounded;
3) The cast aluminum heater should be stored in a dry place. If the insulation resistance is lower than 1MΩ due to long-term storage, it can be restored by baking in an oven at about 200 degrees Celsius for 5-6 hours.
