Lubricating Oil Heater (Oil Warmer, Lubricant Heater)
I. Overview:
Heating oil heaters are primarily used for heating oil-based liquids, such as preheating lubricating oil, heating lubricating oil, preheating fuel oil, preventing oil from solidifying, and heating oil passages during heat treatment, etc.
Section 2: Oil Preheater
It is primarily used in the thin oil circulation lubrication system, placed before the separator to heat the dirty oil lubricant pre-heater before purification, thereby reducing the viscosity of the dirty oil and improving the purification quality.
The oil preheater is mainly composed of the housing and electrical heating elements. The housing is welded into shape using tube plates; the electrical heating elements are of metallic tubular design. The ends of the tubular heating elements are equipped with flanges for sealing and continuous connection to the housing.
Section 3: Oil Heating with Electric Heating Elements
Oil heating is achieved using electric heating elements housed in a lubrication preheater, commonly fitted with a threaded flange. It is not only used in various oil heaters with casings but can also be used as a standalone product. Typically, it is installed in open or closed oil tanks to heat oil and can also be used to melt asphalt, paraffin, and other solid oils. It can also be mounted in an oil circuit system to heat flowing oil.
The key in using oil-heating electrical heating elements is to ensure the heating portion is fully immersed in the oil being heated. Otherwise, it will affect its lifespan.
