Problems solved by technology
[0002] Electric heaters often encounter the problem of low pressure and small flow during the heating process. In the occasion of high temperature heating of gas medium, the traditional electric heater cannot meet the occasion of low pressure heating due to its complex structure and high pressure; and the traditional Electric heaters often generate high-temperature alarms, which cannot fully heat the heated medium and fail to meet the outlet temperature requirements. In order to meet the temperature requirements, the electric heater will shorten its service life due to over-temperature
