BGY8-220V/1.5KW Explosion-proof Electric Heater Features
Composed of heating core and sheath. The heating core uses metal tubular electric heating elements as the heat source, and the sheath is made of cold-drawn seamless steel pipe or stainless steel pipe. The electric heater is connected to the oil tank body by flange. The sheath isolates the heating core from the heated oil. When replacing the electric heater, it is not necessary to drain the oil from the tank; only the heater core needs to be pulled out and replaced with a new one, making maintenance convenient. The electric heater has a large contact area with the heated oil, low surface thermal power, no carbon deposition, and the oil will not carbonize due to local high temperature. Long service life, safe and reliable.
Precautions:
1. The element is allowed to work under the following conditions:
A. The relative humidity of the air is not more than 95%, and there are no explosive or corrosive gases. Except for explosion-proof heaters
B. The working voltage should not exceed 1.1 times the rated value, and the shell should be effectively grounded.
C. Insulation resistance ≥ 1MΩ, dielectric strength: 2KV/1min.
2. The electric heating tube should be properly positioned and fixed, and the effective heating area must be fully immersed in liquid or metal solid. ,Do not dry burn. If scale or carbon deposits are found on the tube surface, they should be cleaned promptly before reuse to avoid affecting heat dissipation and shortening service life.
3. When heating fusible metals or solid nitrates, alkalis, asphalt, paraffin, etc., the operating voltage should be reduced first, and then raised to the rated voltage only after the medium has melted.
4. When heating air, the elements should be arranged crosswise and evenly to ensure good heat dissipation conditions and fully heat the flowing air.
5. When heating nitrates, safety measures should be considered to prevent explosion accidents.
6. The wiring part should be placed outside the insulation layer to avoid contact with corrosive, explosive media, and moisture; the lead wire should be able to withstand the temperature of the wiring part and the heating load for a long time, and avoid excessive force when tightening the wiring screws.
