1) The working voltage must 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°C for 5-6 hours.
Ordering information:
1) The user should provide product drawings or samples. If no drawings or samples are available, the product specifications, model, voltage, power, etc. must be provided.
2) The surface power density of the cast aluminum electric heater is between 2.5 and 4.0 W/cm².
