Features:
1. Fast heating speed, high heat transfer efficiency, not easy to scale.
2. SRY2 tubular electric heater can quantitatively heat oil, heating as much as needed.
3. No local high temperature or carbonization of oil, ensuring oil quality and heater heat transfer efficiency.
4. The oil outlet temperature in the tank is the highest, ensuring the fluidity of the drained oil.
5. Avoids repeated heating of oil in the tank, ensuring oil color and reducing oil processing costs.
6. Long service life, corrosion resistance, high temperature resistance, high pressure resistance, anti-scaling function, greatly improving the overall performance of the heat exchanger.
Process:
The heating tube is made by inserting electric heating wire into an outer tube (carbon steel tube, titanium tube, stainless steel tube, copper tube), filling the gaps with magnesium oxide powder that has good thermal conductivity and insulation, then shrinking the tube. After heat treatment (some tubes do not require it), it is processed into various shapes as needed by the user. It has simple structure, high thermal efficiency, good mechanical strength, and good adaptability to harsh environments. It can be used for heating various liquids and acid-base salts, and is also suitable for melting low-melting-point metals.
Scope of application for tubular heaters: Suitable for heating air, oil, water, chemical media, hot pressing molds, melting salts, alkalis, and low-melting-point alloys, etc. It features high thermal efficiency, long service life, high mechanical strength, easy installation, safety, and reliability.
Classification of tubular heaters by shape: According to different shapes, heating tubes can be divided into: straight single-end heating tubes, straight double-end heating tubes, U-shaped heating tubes, W-shaped heating tubes, special-shaped heating tubes, and spiral heating tubes.
Precautions:
1. Dimension "B" in the outline drawing must be fully immersed in oil to avoid damaging the element. The heated oil should be non-corrosive.
2. The working liquid level of SRY2 tubular electric heater must be below the fastener and above the dimension line "B".
3. When melting solid oils such as asphalt and paraffin, reduce the voltage first, then increase to rated voltage after melting to prevent heat concentration and reduce element service life.
4. If carbon deposits are found on the tube surface, they must be removed before reuse to avoid reducing efficiency or even burning out the element.
5. The element should be stored in a dry place. If the insulation resistance drops below 1 megohm due to long-term storage, it can be restored by drying in an oven at about 200°C for several hours (or by applying low voltage to the element for several hours).
