SRY6-2 Sheathed Electric Heater Features and Instructions
Features:

1. The sheathed tubular electric heater consists of a heating core and a protective sheath. The heating core uses a tubular electric heating element as the heat source, and the protective sheath is made of thin stainless steel. It has a large heat dissipation area and fast heat transfer. The terminal connection part is divided into ordinary type (using an iron drawn cup-shaped cover) and special type (using a bolted explosion-proof device cover seal). The special type meets the requirements of the explosion-proof mark DIICT4 and protection level IP65 series standards.

2. The electric heater is connected to the oil tank container body by flanges. The protective sheath isolates the heating core from the heated oil. When repairing the electric heater, there is no need to drain the oil from the tank; only the heating core needs to be extracted and replaced with a new one, making maintenance convenient.

3. When designing the sheathed tubular electric heater, the contact area between the sheath and the heated oil should be considered to prevent the oil from local carbonization due to excessively high heating temperature. This type of heater is only suitable for heating oil with good heat transfer performance.

Instructions:

1. The working voltage must not exceed 1.1 times its rated value, and the housing should be effectively grounded.
2. The 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 of this electric heater is φ65mm.
4. The tubular electric heating element is designed according to the 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 dimensions of the heating medium.
