SRY6-2 380V/6 Sheathed Tubular Electric Heater Precautions:
1. The element is allowed to work under the following conditions: A. Relative air humidity not greater than 95%, no explosive or corrosive gases. 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 fixed, and the effective heating area must be fully 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., the operating voltage should be reduced first, and then raised to the rated voltage only after the medium has melted.
4. When heating air, the elements should be arranged crosswise and evenly to ensure good heat dissipation conditions and allow the flowing air to be fully heated.
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, or moisture. The connecting 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.

Features:
The SRY6-2 380V/6KW sheathed tubular electric heater consists of a heating core and a sheath. The heating core uses a metal tubular electric heating element as the heat source, and the sheath is made of cold-drawn seamless steel pipe or stainless steel pipe. The electric heater is connected to the oil tank body by flange. The sheath isolates the heating core from the heated oil. When replacing the electric heater, it is not necessary to drain the oil from the tank; only the heating core needs to be pulled out and replaced with a new one, making maintenance convenient. The electric heater has a large contact area with the heated oil, low surface heat power, no carbon deposition, and the oil will not carbonize due to local high temperature. It has a long service life and is safe and reliable.
Routine Maintenance:
1. After the heater has been in operation for a period of time (depending on user conditions), unscrew the combustion plug to clean carbon deposits. If the ignition plug wire is burned out, remove and replace it with a new one.
2. If excessive carbon deposits cause a decrease in thermal efficiency, clean the heat dissipation fins on the inner wall of the water jacket and the carbon deposits in the combustion chamber.
3. If the heater's air intake pipe, exhaust pipe, or oil drip pipe are blocked by mud, clean and unblock them promptly. Keep the heater compartment clean, and do not place flammable debris nearby.
4. Ensure the fuel tank, oil pipes, and fuel filter solenoid valve are clean to prevent dirt from blocking the oil circuit.
5. In the heater circulation system, use antifreeze suitable for the ambient temperature as the circulating heating medium.
6. The heater water pump should be inspected periodically based on user conditions. If water leakage from the mechanical seal or difficulty in starting the pump is found, repair it promptly.
