HRY1HRY2|HRY3 Sheathed Tubular Electric HeaterProduct Usage:
Used for heating hydraulic oil and lubricating oil in hydraulic and lubrication devices, and also for heating non-corrosive gases or liquids.
HRY1HRY2|HRY3 Sheathed Tubular Electric HeaterPrecautions:
1. 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 dried in an oven at about 200°C for several hours (or apply low voltage for several hours) to restore the insulation resistance.
2. If carbon deposits are found on the tube surface, they must be completely removed before reuse to avoid reducing efficiency or even burning out the element.
3. When melting solid oils such as asphalt and paraffin, reduce the voltage during use, and then increase to the rated voltage after melting. This prevents concentrated power from reducing the element's service life.
Product Features:
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; simply remove the heating core and replace it 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 carbonize due to local high temperature. It has a long service life, is safe, and reliable.
Description:
The electric heater is not allowed to be used above the boiling point of the heating medium at atmospheric pressure.
Used for preheating heavy oil, lubricating oil, diesel, and similar media in wind power applications. SRY6-2 maximum working temperature 100°C, maximum usage temperature shall not exceed 300°C. The user can increase or decrease the number of heaters according to the quantity of heating medium, heating time, and temperature rise limit.
Since the heating tubes are arranged in a fluid manner, the heater can heat the medium very uniformly. The replaceable electric heating tubes are inserted into the heater container, and there is no need to drain the heated medium when replacing the heater.
If the surface load of the selected heater is low, it can avoid bubble formation and carbonization of the heating medium.
