Note: The mounting hole for SRY2 and SRY4 types is Ø72 mm.
2. Operating voltage tolerance: not exceeding 1.1 times the rated value; the casing must be effectively grounded.
3. Operating environment: relative humidity not greater than 95%, free from explosive and corrosive gases.
4. Metal tube material: No. 10 steel.
5. Maximum operating temperature: SRY2 and SRY3: 300°C, SRY4: 100°C.
6. Operating pressure for SRY2 and SRY4 types: less than 2 kg/cm².
7. Fastener length for SRY3 type: 25 mm.
III. Usage, Maintenance, and Precautions
1. Dimension "B" in the outline drawing must be fully immersed in oil to avoid damaging the element. The heated oil should be non-corrosive.
2. For SRY3 type, the working liquid level must be below the fastener and above dimension line "B".
3. When melting solid oils such as asphalt or paraffin, reduce the voltage until melted, then increase to rated voltage to prevent heat concentration and extend element life.
4. If carbon deposits are found on the tube surface, remove them completely before reuse to avoid reduced efficiency or element damage.
5. Store elements in a dry place. If insulation resistance drops below 1 MΩ due to prolonged storage, dry in an oven at about 200°C for several hours (or apply low voltage for several hours) to restore insulation resistance.
