Brief introduction of tubular electric heater:

Tubular electric heater consists of a metal tube, spiral wire resistance and thermal conductivity, insulation of electrical grade magnesium oxide powder, cause terminal, etc., wherein, widely used in liquid and air heating, common have water heaters, ovens, coffee pot and so on.

Main features of tubular electric heater:

1, the electric heater is a heating core and a sheath pipe, heating core with tubular electric heating element as the heat source, the sheath tube with thin stainless steel made. It larger radiating area, fast heat transfer, terminal device is divided into two parts: the common type (using iron tensile cup type casing) and special type (with bolts type flame proof device shell seal), special type has reached explosion-proof mark dIICT4. protection grade IP65 standard requirements.

2, the electric heater and tank container body by flange connection, sheath will heating core with heated oil isolation, in the maintenance of electric heater, do not need to drain the oil liquid in the tank, only need to draw out the heating core, a new heating core can be replaced and convenient maintenance.

3, in the design should consider sheath and hot gas liquid contact area, so that the oil is not because of high temperature and partial carbonization, the types of heaters apply only to heat conduction oil or heated better oil and medium heating.
