Introduction of BGY3KV Explosion-Proof Electric Heater
DARUI Electric recommends for you
The BGY3KV explosion-proof electric heater uses U-shaped tubular heating elements. According to the design specifications for different heating media and the power configuration requirements, it is assembled on the flange cover and inserted into the material to be heated. The large amount of heat generated by the heating element during operation is conducted to the heated medium, raising its temperature to meet the required process conditions.
Product Application:
Mainly used for heat preservation and heating of materials in various storage tanks, containers, and oil tanks in industries such as petroleum, chemical, food, and machinery. The connection method can be flange type or threaded end face seal.
The BGY2-220V/2KW explosion-proof electric heater uses round flange and square flange forms (square flange is indicated by adding F after the model). The selected voltage can be 220V or 380V, and a temperature controller can be installed in the wiring chamber. It provides greater convenience for users, has a long service life, and stable quality.
The reserved hole for flange connection is ≥Φ95. If a temperature controller is required, the reserved hole is ≥Φ110, and "T" is added after the model. The design pressure is 1.6MPa, and the material is all stainless steel.
The explosion-proof grade of the explosion-proof electric heater is dⅡBT4. The steel pipe wiring for 380V is M24×1.5; for 220V, it is M20×1.5.

BGY2-220V/3KW Explosion-Proof Electric Heater Usage, Maintenance, and Precautions:
1. Dimension "B" in the outline drawing must be fully immersed in the oil to avoid burning the component.
2. The heated medium should be non-corrosive.
3. When melting solid oils such as asphalt and paraffin, reduce the voltage during melting, then increase to rated voltage after melting to prevent excessive heat concentration that reduces the service life of the element.
4. If carbon deposits are found on the surface of the heating tube, they must be completely removed before reuse to avoid reduced efficiency or even burning of the component.
5. The heater should be stored in a dry place. If the insulation resistance drops below 1 megohm after long-term storage, it can be restored by drying in an oven at about 200°C for several hours (or by applying low voltage to the component for several hours).
Drying in an oven for several hours (or applying low voltage to the component for several hours) can restore the insulation resistance.
