SRY6-2 Type 380V/6 Sheathed Tubular Electric Heater Attention
The product consists of a heating core and a sheath. The heating core uses high-temperature resistant alloy electric heating wire as the heat source, high-temperature resistant ceramic as the insulation medium, and the sheath is made of cold-drawn seamless steel pipe or stainless steel.
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, there is no need 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 power, no carbon deposition, and the oil will not be locally overheated and carbonized. It has a long service life, is safe, and reliable.

Instructions:
1. The working voltage must not exceed 1.1 times its rated value, and the housing should be effectively grounded.
2. Dimension "B" in the figure must be fully immersed in the oil (and checked regularly) to avoid burning; the heated oil should be free of corrosive gases.
3. The mounting hole size for this electric heater is φ65mm.
4. The tubular electric heating element is designed according to JB2379-78 flowing oil standard, with a surface load of 2-3.8 w/cm2.
5. When selecting, the heater size should be determined based on the actual size of the heating medium.
Maintenance:
1) Regularly clean the heater according to the actual working mode and the contamination level of the fluid. Use an appropriate cleaning solution to flush away muddy deposits, while solid deposits inside or in recessed areas of the element require disassembly of the heating element assembly for removal. To avoid damaging the heating element or the recessed areas of the heater, use a suitable solvent for cleaning.
2) Only the conduit side of the heating element assembly can be cleaned with liquid cleaner or solvent.
3) After cleaning the heater, reassemble the heater in reverse order of the above procedures, replace the new flange gasket, and test the heating elements.
4. Troubleshooting and Repair
4.1 Low heating power, low heating temperature:
1) Check the heating elements and wiring
2) Check the function and setting of the temperature controller
3) Clean the heating element assembly
4.2 Normal heating power, high heating temperature:
1. Check the function and setting of the temperature controller
4.3 Low insulation resistance of heater to ground
1) Check if there is debris in the wiring device
2) Check if the heater is damp
3) Check if the cable has any damage
5. Replace the heating element
