SRY8 (HRY8.HRY9*) Finned Tube Sheathed Electric Heater I. Purpose: This electric heater is used for heating media in hydraulic lubrication systems, suitable for heating non-corrosive gases and liquids.
II. Features The finned tube sheathed electric heater consists of a "metal tubular heating element" and a finned protective tube. The finned protective tube is made of seamless steel pipe, metal fins, and heat-resistant (≤300°C) asbestos rubber sealing gaskets.
The electric heater is fixed to the oil tank body via flange connection; sealed by gaskets; the finned protective tube isolates the metal tubular heating element from the heated medium. When replacing the metal tubular heating element, it is not necessary to drain the oil from the tank; only the metal tubular heating element needs to be extracted for replacement. It is convenient and reliable for use, maintenance, and repair.
In this finned tube sheathed electric heater, the fins and the protective tube are assembled components. Changing the number of fins can alter the surface load of the electric heater. Proper application can prevent oil carbonization and burning, ensuring safety, reliability, and extending the life of the medium.
