Immersion Electric Heating Coil Instructions
1. The working voltage must not exceed 1.1 times its rated value. The shell should be effectively grounded.
2. Working environment: humidity not greater than 95%, no explosive or corrosive gases.
3. Dimension “C” in the figure must be fully immersed in oil (and checked regularly) to avoid burning. The heated oil should be non-corrosive.
4. When melting solid oils such as asphalt and paraffin, reduce the voltage, and then increase to rated voltage after melting.
5. If carbon deposits are found on the tube surface, they must be removed before reuse to avoid reduced efficiency or even burning.
6. Keep the outlet end dry and clean to avoid surface flashover or short circuit.
7. The element should be stored in a dry and ventilated place. If the insulation resistance to ground drops below 1MΩ after long-term storage, it can be restored by drying in an oven at about 200°C for several hours.
   8. For JGY2 and JGY4 types, the mounting hole is φ66mm; for JGY3 type, the fastener is M18*1.5, length 25mm.

Immersion Electric Heating Coil Technical Parameters

Rated voltage:       Single-phase 220V    Three-phase 380V

Surface heating power: Type 4 and 5 ≤1.8W/cm²    Type 6 and 7 ≤0.7W/cm²

Heat transfer temperature:       ≤300°C

Working medium:       Mineral oil
