HRY Tubular Electric Heater with Round Tube Sheath
Used for heating hydraulic and lubricating oil in hydraulic and lubrication devices, and can also be used to heat non-corrosive gases or liquids.
Product Features:
1. It adopts the form of multiple U-shaped electric heating elements matched with multiple special-shaped sheaths, which has the characteristics of large heat dissipation area, fast heat transfer, and long service life. It is also convenient for replacement and maintenance.
2. Due to the use of multiple U-shaped electric heating elements matched with multiple special-shaped sheaths, if a certain heating element is damaged, only the damaged heating 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. The surface load of standard parts is designed as 0.7 watts per square centimeter.
4.Sheathed tubular electric heater can be optionally 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 number; if automatic constant temperature function is required, the heater should be equipped with a thermostat and contactor, and the letter "TH" should be added after the model number when ordering.
5. Working voltage allowable error: not greater than 1.1 times its rated value. The shell should be effectively grounded.
6. Working environment: relative humidity not greater than 95%, no explosive, flammable, and corrosive gases.
7. Heater material: carbon steel or stainless steel.
8. Maximum working temperature: 200°C.
9. Working pressure: less than 0.6MPa
10. Specifications and overall dimensions: see the table and attached drawings on the next page
Usage, Maintenance, and Precautions:
1. The dimension "B" in the overall dimension drawing must be fully immersed in the oil to avoid burning out the components.
2. The heated medium should be non-corrosive.
3. When melting solid oils such as asphalt and paraffin, the voltage should be reduced, and after melting, raise to the rated voltage to prevent excessive heat concentration from reducing the service life of the components.
4. If carbon deposits are found on the surface of the heating tube, they must be completely removed before use to avoid reducing efficiency or even burning out the components.
5. The components should be stored in a dry place. If the insulation resistance drops below 1 megohm after long-term storage, the heating core can be taken out and dried in an oven at about 200°C for several hours (or the components can be powered at low voltage for several hours) to restore the insulation resistance.
