Product Application:
Used for heating hydraulic oil and lubricating oil in hydraulic and lubrication devices, also can be used for heating non-corrosive gas or liquid.
Precautions:
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 to prevent concentrated power from reducing the service life of the element.
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 insulating 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, it is not necessary to drain the oil from the tank; only need to pull out the heating core and replace it with a new one, making maintenance convenient.
