Application

HRY series sheathed tubular electric heaters are used for heating hydraulic oil and lubricating oil in hydraulic and lubrication systems, and can also be used to heat non-corrosive gases or liquids.

Features

HRY series sheathed tubular electric heaters consist of a heating core and a sheath. The heating core uses high-temperature resistant alloy electric heating wire as the heat source, high-temperature resistant ceramic as the insulating medium, and the sheath is made of cold-drawn seamless steel pipe or stainless steel.

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, it is not necessary to drain the oil from the tank; only the heating core needs to be pulled out and replaced with a new one, making maintenance convenient.

The electric heater has a large contact area with the heated oil, low surface power, no carbon deposition, and the oil will not be carbonized due to local high temperature. It has a long service life, and is safe and reliable.
