Product Details

Product Introduction:

Used for heating hydraulic and lubricating oil in hydraulic and lubrication devices, also can be used to heat non-corrosive gas or liquid.

Composed of heating core and sheath. The heating core uses high-temperature resistant alloy electric heating wire as heat source, high-temperature resistant ceramic as 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 HRY sheath heater isolates the heating core from the heated oil. When replacing the electric heater, it is not necessary to drain the oil in the tank, only need to pull out the heating core and replace it with a new one, easy maintenance.
The electric heater has a large contact area with the heated oil, low surface power, no carbon deposition, and the oil will not be carbonized due to local high temperature. Long service life, safe and reliable.
