HRY Tubular Electric Heater with Round Tube Sheath
1. In the dimensional drawing, dimension "B" must be fully immersed in the oil to avoid burning the component.
2. The heated medium should be non-corrosive.
3. When melting solid oils such as asphalt and paraffin, reduce the voltage during use, and then increase to rated voltage after melting to prevent excessive heat concentration and reduce the service life of the component.
4. If carbon deposits are found on the surface of the heating tube, remove the carbon completely before reuse to avoid reducing efficiency or even burning the component.
5. The component should be stored in a dry place. If the insulation resistance drops below 1 megohm after long-term storage, the heating core can be removed and dried in an oven at about 200°C for several hours (or the component can be powered at low voltage for several hours) to restore the insulation resistance.

Used for heating hydraulic and lubricating oil in hydraulic lubrication devices, and can also be used to heat non-corrosive gases or liquids.
Product Features:
1. Adopting multiple U-shaped electric heating elements with multiple special-shaped sheaths, it has the characteristics of large heat dissipation area, fast heat transfer, long service life, and easy replacement and maintenance.
2. Due to the use of multiple U-shaped electric heating elements with multiple special-shaped sheaths, if a certain electric heating element is damaged, only that 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 requirements. The standard surface load design is 0.7 W/cm².
4. Sheathed Tubular Electric Heater can be equipped with liquid expansion thermostat, manual reset, AC contactor and other electrical equipment. If the heater needs temperature adjustment function, only the temperature control equipment needs to be installed. When ordering, add the letter "T" after the model; if automatic constant temperature function is required, the heater should be equipped with a thermostat and contactor, and add the letters "TH" after the model when ordering.
5. Working voltage tolerance: not greater than 1.1 times the rated value. The shell should be effectively grounded.
6. Working environment: relative humidity not greater than 95%, no explosive, flammable or corrosive gases.
7. Heater material: carbon steel or stainless steel.
8. Maximum working temperature: 200°C.
9. Working pressure: less than 0.6 MPa
10. Specifications and dimensions: see the table and figure on the next page
