SRY2, SRY4 Tubular Electric Heaters Yangzhou Darui
Darui Electric recommends
Specifications and dimensions: see Table 1 and Figure 1-2
2. Working voltage tolerance: not greater than 1.1 times its rated value. The shell should be effectively grounded.
3. Working environment: relative humidity not greater than 95%, no explosive, flammable, or corrosive gases.
4. Metal tube material: No. 10 steel.
5. Working temperature: 100°C.
6. Working pressure of SRY2 and SRY4 types is less than 0.6MPa.
7. Oil tank opening: ≥φ65.
3. Usage, maintenance, and precautions:
1. Dimension "B" in the outline drawing must be fully immersed in oil to avoid burning the component. The heated oil should be non-corrosive.
2. When melting solid oils such as asphalt and paraffin, use reduced voltage until melted, then increase to rated voltage to prevent heat concentration and reduce component lifespan.
3. If carbon deposits are found on the tube surface, remove them completely before reuse to avoid reduced efficiency or even burning of the component.
4. Store components in a dry place. If insulation resistance drops below 1 megohm due to long-term storage, dry in an oven at about 200°C for several hours (or apply low voltage to the component for several hours) to restore insulation resistance.
