SRY6-2 (380V/3W) Sheathed Tubular Electric Heater Price Application:

Used for heating hydraulic oil and lubricating oil in hydraulic and lubrication devices, also can be used for heating non-corrosive gases or liquids.

 Main Technical Parameters:

Rated Voltage: Single-phase 220V, Three-phase 380V
Surface Heating Power: As far as possible ≤0.7/cm2 as design standard
Heat Transfer Temperature: ≤300℃
Working Medium: Mineral
Working Pressure: ≤0.8Mpa

 Precautions:

1. The element is allowed to work under the following conditions:
A. Relative humidity of air not greater than 95%, no explosive or corrosive gases. (Except for explosion-proof heaters)
B. Working voltage should not exceed 1.1 times the rated value, and the shell should be effectively grounded.
C. Insulation resistance ≥1MΩ Dielectric strength: 2KV/1min.
2. The electric heating tube should be properly positioned and fixed, and the effective heating area must be completely immersed in liquid or solid metal. Dry burning is strictly prohibited. If scale or carbon deposits are found on the tube surface, they should be cleaned promptly before reuse to avoid affecting heat dissipation and shortening service life.
3. When heating fusible metals or solid nitrates, alkalis, asphalt, paraffin, etc., first reduce the operating voltage, and only increase to the rated voltage after the medium melts.
4. When heating air, the elements should be arranged crosswise and evenly to ensure good heat dissipation and adequate heating of the passing air.
5. When heating nitrates, safety measures should be considered to prevent explosion accidents.
6. The wiring part should be placed outside the insulation layer to avoid contact with corrosive, explosive media, and moisture. The lead wires should be able to withstand the temperature of the wiring part and the heating load for a long time. When tightening the wiring screws, avoid excessive force.
7. The element should be stored in a dry place. If the insulation resistance is lower than 1MΩ due to long-term storage, it can be dried in an oven at about 200℃ or heated by reducing voltage until the insulation resistance is restored.
8. The magnesium oxide powder at the outlet end of the electric heating tube should avoid contamination and moisture penetration at the use site to prevent leakage accidents.
