Sheath type tubular electric heater

Product Usage

Used for heating hydraulic and lubricating oil in hydraulic lubrication devices, as well as for heating non corrosive gases or liquids.

Product Features:

1. It adopts the form of multiple U-shaped electric heating elements with multiple special-shaped sheaths, which has a large heat dissipation area, fast heat transfer, and long service life. Features such as easy replacement and maintenance.

2. Due to the use of multiple U-shaped electric heating elements with multiple special-shaped sheaths, if one electric heating element is damaged, only the damaged element needs to be replaced without replacing the entire heating source, greatly reducing the subsequent investment of the user.

3. The surface load design can be determined according to customer needs, with a standard surface load design of 0.7 watts per square centimeter.

4.SRY6-4-380V220V6KW 型Sheath type tubular electric heaterOptional electrical equipment such as liquid expansion temperature controller, manual reset, AC contactor, etc. If the heater needs to have temperature control function, only temperature control equipment needs to be installed on the heater,

Add the model number after the customer's order

The letter 'T'; If automatic constant temperature function is required, the heater should be equipped with a temperature controller and contactor, and the letter "TH" should be added after the model when ordering.

5. Allowable error of working voltage: not greater than 1.1 times its rated value. The casing should be effectively grounded.

6. Working environment: The relative humidity should not exceed 95%, and there should be no explosive, flammable, or corrosive gases.

7. Heater material: carbon steel or stainless steel.

8. Maximum working temperature: 200 ℃.

9. Work pressure: less than 0.6MPa

10. Specifications and external dimensions: see the table and attached drawings on the next page

SRY6-4-380V220V6KW 型Sheath type tubular electric heaterUsage, maintenance and precautions:

The dimension "B" in the external dimension diagram must be fully immersed in the oil to avoid burning out the components.

2. The heated medium should be non corrosive.

When melting solid oils such as asphalt and paraffin, the voltage should be reduced and then increased to the rated voltage after melting to prevent excessive heat concentration and reduce the service life of the components.

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

5. Components should be stored in a dry place. If the insulation resistance drops below 1 megaohm after long-term storage, the heating element can be removed and dried in an oven at around 200 ℃ for several hours (or the component can be powered on with low voltage for several hours),

The insulation resistance can be restored.
