Thermal Oil Heater Unique Technical Expression:
| Unique technical design | Function |
| 1.Wet back type smoke-transfer chamber | Fully absorb the back end smoke temperature |
| 2.Three coiled tube and three-pass structure | Extend the time of gas stay in boiler to achieve sufficient heat transfer, with fire surrounded by oil structure |
| 3.Multi-pass oil way design, reverse heat transfer | Rational layout the heat surface, combine the different temperature section for heat transfer layout |
| 4.Lower entrance and higher exit oil flow design | Ensure the rationality of process of medium, the heat transfer oil is from low entrance to high exit, and the medium gas is difficult to stay in the furnace during operation , which can be easily discharged from the system |
| 5.External header design | Preventing the direct heating of the flue gas to the header, causing internal carbonization to ensure safe operation of the boiler |
| 6.Large access door design | Open to the left or right according to the boiler room space |
| 7.Fast hardening casting material of front and rear smoke box | high temperature resistance protection, strong solidification, long life cycle |
| 8.Integrated junction box design | standard circuit |
