Components of electric heater with circular tube sheath:

A circular tube sheathed electric heater is a common industrial heating equipment, mainly used to heat non corrosive gases or liquids, such as hydraulic oil, lubricating oil, etc. Its core feature is to isolate the heating element from the heated medium through a sheath, so that during maintenance, there is no need to empty the oil in the tank, only the heating element needs to be removed for replacement, greatly improving the convenience of maintenance.

Main Features

Structure composition: Composed of a heating core and a protective sheath. The heating core usually uses a metal tubular electric heating element as the heat source, and the sheath is made of cold drawn seamless steel pipe or stainless steel tube.

Safe and reliable: The design of the sheath effectively isolates the heating element from the medium, avoiding oil carbonization caused by local high temperatures and extending the service life of the equipment.

Easy maintenance: No need to empty the medium during maintenance, only replace the heating element, saving time and cost.

Technical specifications

Rated voltage: usually single-phase 220V or three-phase 380V 12.

Applicable scenarios: Widely used in hydraulic and lubrication devices for heating hydraulic oil and lubricating oil, as well as for heating non corrosive gases or liquids.
