Sheathed Electric Heater Application:
SRY6-3 sheathed electric heater is used for heating hydraulic and lubricating oil in hydraulic and lubrication systems, and can also be used for heating non-corrosive gases or liquids.
Features:
1. The sheathed electric heater consists of a heating core and a sheath tube. The heating core uses tubular electric heating elements as the heat source, and the sheath tube is made of thin stainless steel, which has a large heat dissipation area and fast heat transfer. The terminal connection part is divided into ordinary type (using iron-made drawn cup-shaped housing) and special type (using bolted explosion-proof device housing seal). The special type meets the requirements of explosion-proof mark DIICT4 and protection level IP65 series standards.
2. The sheathed electric heater is connected to the oil tank body by flange. The sheath isolates the heating core from the heated oil. When repairing the electric heater, there is no need to drain the oil in the tank; just pull out the heating core and replace it with a new one, making maintenance convenient.
During design, the contact area between the sheath and the heated oil should be considered to prevent local carbonization of the oil due to excessive heating temperature. This model of heater is only suitable for heating oil with good heat transfer effect.
