product introduction
The cast copper electric heater uses electric heating tube as the heating element, which is bent into shape, put into the mold and made of high-quality copper metal material as the shell by centrifugal casting into various shapes, including round, flat, right-angle, air-cooled, water-cooled and other special shapes. After fine processing, it can fit tightly with the heated object.

Installation&Service
Precautions for using cast copper electric heater:
1. The cast copper electric 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℃for 5-6 hours to restore to normal. Or reduce the voltage and heat it until the insulation resistance is restored.
2. The cast copper electric heater should be positioned and fixed, and the effective heating area must fit closely with the heated body. It is strictly forbidden to burn it empty. If dust or contaminants are found on the surface, it should be cleaned in time before use to avoid affecting heat dissipation and shortening the service life.
3. The magnesium oxide powder at the outlet of the electric heating tube of the cast copper electric heater should be protected from pollutants and moisture in the place of use to prevent leakage accidents.
4. The working voltage of the cast copper electric heater shall not exceed 10% of the rated value; the relative humidity of the air shall not exceed 95%, and there shall be no explosive and corrosive gases.
5. The wiring part of the explosion-proof cast copper electric heater shall be placed outside the heating layer and the insulation layer, and the shell shall be effectively grounded; avoid contact with corrosive, explosive media and moisture; the lead wire shall be able to withstand the temperature and heating load of the wiring part for a long time, and excessive force shall be avoided when tightening the wiring screws.
