1、 Purpose:

HRY3-380V/3KW sheathed electric heaterUsed for heating hydraulic and lubricating oil in hydraulic and lubrication devices, as well as for heating non corrosive gases or liquids.

2、 Characteristics:

1、 HRYThe series sheathed electric heater consists of a heating core and a protective sleeve. The heating core uses a tubular electric heating element as the heat source, and the protective sleeve is made of thin stainless steel, which has a large heat dissipation area and fast heat transfer. The terminal device is divided into ordinary type (using an iron stretched cup shaped cover) and special type (using a bolt type explosion-proof device cover for sealing). The special type has reached the explosion-proof markdIICT4.Requirements of IP65 series standards for protection level.

2The electric heater is connected to the fuel tank container body via a flange, and a protective sheath isolates the heating element from the heated oil. When repairing the electric heater, there is no need to drain the oil from the fuel tank. Simply remove the heating element and replace it with a new one, making maintenance convenient.

3When designing, the contact area between the sheath and the hot oil should be considered to prevent local carbonization of the oil due to high heating temperature. This type of heater is only suitable for heating heat transfer oil or oil with good heating effect and medium.
