Save energy consumption, Saving steels. Reduced overall diameter of reactor, conducive to workplace layout.

Outer coil/coil reactor are widely used in petroleum, chemical, rubber, pesticides, dyes, medicines, food and so on.

Reactor  bottom  has discharge hole, and kettle mixer in it , pot lid is opened with feed mixing and observation, temperature, pressure, and steam extraction fractionation and safety vent pipe hole.

On the heating coil with inlet and exhaust oil (gas), such as temperature, vent hole, may be achieved through steam, thermal oil, water heating, or cooling.
