BGY8-220V/2.5KW Explosion-Proof Electric Heater
Composed of a heating core and a sheath. The heating core uses a metal tubular electric heating element 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 a flange. The sheath isolates the heating core from the heated oil. When replacing the electric heater, there is no need to drain the oil from the tank; simply pull out the heating core and replace it 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. It has a long service life and is safe and reliable.
Precautions:
1. The element is allowed to work under the following conditions:
A. Relative humidity of air not greater than 95%, no explosive or corrosive gases. Except for explosion-proof heaters
B. 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 fixed and positioned, and the effective heating zone must be completely immersed in liquid or solid metal; dry burning is strictly prohibited. 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., first reduce the operating voltage, and only after the medium melts can it be raised to the rated voltage.
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 wires should be able to withstand the temperature of the wiring part and the heating load for a long time; when tightening the wiring screws, avoid excessive force.
