HRY4|HRY5|HRY6 Sheathed Electric Heater Detailed Information:
Product Application:
Used for heating hydraulic and lubricating oil in hydraulic lubrication devices, and also for heating non-corrosive gases or liquids.
Product Features:
1. Adopting the form of multiple U-shaped electric heating elements with multiple special-shaped sheaths, it has the characteristics of large heat dissipation area, fast heat transfer, and long service life. Easy to replace and maintain.
2. Due to the use of multiple U-shaped electric heating elements with multiple special-shaped sheaths, if a certain 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 needs. 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 regulation 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 0.6MPa
10. Specifications and dimensions: see the table and 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, use reduced voltage until melted, then raise to rated voltage 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.
