SRY2-220V/3KW Ordinary Tubular Electric Heater
High Quality SRY2-220V/3KW Ordinary Tubular Electric Heater Function Description:
Working voltage tolerance: not greater than 1.1 times its rated value, the shell must be effectively grounded.
Working environment: relative humidity not greater than 95%, no explosive or corrosive gases.
In the outline drawing, "B" must be fully immersed in oil (and checked regularly) to avoid burning; the heated oil should be non-corrosive. When melting solid oils such as asphalt and paraffin, reduce the voltage for use, then increase to rated voltage after melting. To prevent heat concentration and reduce element service life. Keep the outlet end dry and clean to avoid surface flashover or short circuit. The element should be stored in a dry place. If the insulation resistance drops below 1MΩ due to long-term storage, it can be dried in an oven at about 200°C for several hours (or apply low voltage to the element for several hours) to restore insulation resistance.

High Quality SRY2-220V/3KW Ordinary Tubular Electric Heater Features:

1. This model of electric heater is manufactured by imitating German products. The electric heater consists of a heating core and a protective tube. The heating core uses a tubular electric heating element as the heat source, and the protective tube is made of thin stainless steel tube. The wiring device protection adopts a bolted cover seal, which is waterproof, moisture-proof, and oil-proof.
2. The protective tube and the oil tank body are connected by straight pipe threads, with strong sealing. The protective tube isolates the core from the heated oil. When replacing the electric heater, there is no need to drain the oil in the tank; only the heater core needs to be pulled out, making maintenance convenient.
3. The surface power of this model of electric heater is designed according to the JBT2379-93 standard, and its surface power should be selected at ≤0.7W/cm².
