4kw Sheath Type Electric Heater Element Customizable Description: - Yangzhou Darui
Darui Electric recommends
The electric heater is not allowed to be used above the boiling point of the heating medium under atmospheric pressure.
Used for preheating heavy oil, lubricating oil, diesel and similar media in wind power applications. SRY6-2 maximum working temperature 100℃, maximum use temperature shall not exceed 300℃. 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-like manner, the heater can heat the heating medium very uniformly. The replaceable electric heating tubes are inserted into the heater container. When replacing the heater, there is no need to drain the heated medium.
If the surface load of the selected heater is low, it can avoid bubble formation and carbonization of the heating medium.

Product Application:
Used for heating hydraulic oil and lubricating oil in hydraulic and lubrication devices, also can be used for heating non-corrosive gases or liquids.
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 in 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 carbonize due to local high temperature. Long service life, safe and reliable.
