HRY Tubular Electric Heater with Round Tube Sheath
Used for heating hydraulic and lubricating oil in hydraulic lubrication devices, and also for heating non-corrosive gases or liquids.
Product Features:
1. Adopts multiple U-shaped electric heating elements with multiple special-shaped sheaths, featuring large heat dissipation area, fast heat transfer, long service life, and convenient replacement and maintenance.
2. Due to the use of multiple U-shaped electric heating elements with multiple special-shaped sheaths, if one heating element is damaged, only that element needs to be replaced without replacing the entire heating source, greatly reducing the user's subsequent investment.
3. The surface load design can be determined according to customer requirements; the standard surface load is designed as 0.7 W/cm².
4. Sheath-type 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 device needs to be installed. When ordering, add the letter "T" after the model number; if automatic constant temperature function is required, the heater must be equipped with a thermostat and contactor, and add the letters "TH" after the model number 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 0.6MPa
10. Specifications and dimensions: see the table and attached figure on the next page
Usage, Maintenance and Precautions:
1. Dimension "B" in the outline drawing must be fully immersed in the oil to avoid burning the components.
2. The heated medium should be non-corrosive.
3. When melting solid oils such as asphalt and paraffin, reduce the voltage for use, then increase to rated voltage after melting to prevent excessive heat concentration and reduce component life.
4. If carbon deposits are found on the surface of the heating tube, remove the carbon completely before reuse to avoid reduced efficiency or even burning of components.
5. Components should be stored in a dry place. If the insulation resistance drops below 1 megohm after long-term storage, remove the heating core and dry it in an oven at about 200°C for several hours (or apply low voltage to the component for several hours) to restore insulation resistance.
