I. Purpose:
HRY2-220V/2KW sheathed electric heater is used for heating hydraulic and lubricating oil in hydraulic and lubrication devices, and can also be used for heating non-corrosive gases or liquids.
II. Features:
1. The HRY series sheathed electric heater consists of a heating core and a protective sheath. The heating core uses tubular electric heating elements as the heat source, and the protective sheath is made of thin stainless steel. It has a large heat dissipation area and fast heat transfer. The terminal device part is divided into ordinary type (using iron-made stretched cup-shaped housing) and special type (using bolted explosion-proof device housing seal). The special type meets the explosion-proof mark dIICT4. and protection level IP65 series standard requirements.
2. The electric heater is connected to the oil tank container body by flange. The protective sheath isolates the heating core from the heated oil. When maintaining the electric heater, there is no need to drain the oil in the tank. Simply pull out the heating core and replace it with a new one, making maintenance convenient.
3. 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 heat transfer oil or oils and media with good heat absorption effect.
