1、 Purpose:

SRY2-220V/3KW immersion electric heaterUsed for heating oil in open or closed oil tanks,SRY4The tubular electric heating component is used to heat flowing or circulating oil. This type of heater has a high surface load and is only suitable for use in oil with good heating effect.

2、 Specifications and technical parameters:

1. Specifications and external dimensionsSee Table 1 and Figure 1-2

2.Allowable error of working voltage: not greater than its rated value1.1Twice. The casing should be effectively grounded.

3.Working environment: Relative humidity not exceeding95%No explosive, flammable, or corrosive gases.

4.Metal tube material:10Number steel.

5.Maximum operating temperature:100℃.

6.SRY2TypeSRY4The work pressure of the type is less than0.6MPa.

7.Fuel tank opening: ≥ φ65.

3、 Usage, maintenance and precautions:

1.Dimensions in the external dimension diagram“B”It must be completely immersed in oil to avoid burning out the components. The heated oil should be non corrosive.

2. SRY2-220V/3KW immersion electric heaterWhen melting solid oils such as asphalt and paraffin, the voltage should be reduced and then increased to the rated voltage after melting. To prevent heat concentration from reducing the lifespan of components.

3. When carbon deposits are found on the surface of the pipe, they must be removed completely before use to avoid reducing efficiency and even burning out components.

4.Components should be stored in a dry place. If the insulation resistance drops below due to long-term storage1At megaohms, it can be200Dry in an oven at around ℃ for several hours (or apply low voltage to the components for several hours) to restore insulation resistance.
