Precautions for the use of thick film heating elements

1. In the outline dimension drawing of the thick film heater, all the parts marked with red size must be immersed in liquid to avoid burning out the components. The heated liquid should be non-corrosive.

2. The working fluid level of SRY3 type must be below the fastener and above the red mark of the dimension line.

3. When melting bitumen, paraffin and other solid oils, the voltage should be lowered for use, and then raised to the rated voltage after melting. To prevent power concentration and reduce component life.

4. When carbon buildup is found on the surface of the tube, it must be cleaned before use to avoid reducing the efficiency or even burning the components.

5. The thick film heating element should be stored in a dry place. If the insulation resistance drops below 1 megohm due to long-term storage, it can be dried in an oven at about 200°C for several hours, or the element can be passed under low pressure for several hours to recover. Insulation resistance.
