Darui Electric recommends
The terminal device part is divided into ordinary type using iron drawn cup-shaped casing, and special type using bolt-type explosion-proof device casing seal. It meets the requirements of explosion-proof mark dⅡBT4 and protection level IP54 series standards.
Product Application:
Used for heating hydraulic oil and lubricating oil in hydraulic and lubrication devices, also can be used to heat non-corrosive gases and liquids.
Product Features:
Composed of heating core and sheath. The heating core uses metal tubular electric heating element as heat source, and the sheath is made of cold-drawn seamless steel pipe or stainless steel pipe.
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; just pull out the heating core and replace it with a new one, easy maintenance.
The electric heater has large contact area with the heated oil, low surface heat power, no carbon deposition, and the oil will not carbonize due to local high temperature. Long service life, safe and reliable.
