The stainless steel internal coil reactor is a reaction vessel that features a spiral coil installed inside the reactor body as the heat exchange element. The coil is directly immersed in the material, allowing rapid heat exchange between the heating/cooling medium flowing through the coil and the material. This reactor is widely used in chemical, pharmaceutical, food, and fine chemical industries for heating, cooling, and constant-temperature control processes.
Key Considerations
1、Suitable for low to medium viscosity materials: High-viscosity materials may adhere to the coil surface, reducing heat transfer efficiency
2、Potential for crystallization or fouling: Some materials may crystallize or form scale on the coil surface – requires regular cleaning
3、Agitator design must be compatible: Avoid interference between the impeller and the coil; consider eccentric agitation or a draft tube if needed
4、Pressure drop exists: Long coils create flow resistance – ensure adequate pumping capacity
Main Component
| Component | Description |
| Vessel Body | Stainless steel (304 or 316L), corrosion-resistant and easy to clean |
| Internal Coil | Spiral stainless steel coil installed inside the vessel – the primary heat exchange element |
| Agitator | Anchor, paddle, frame, or turbine type – ensures material mixing and uniform heat transfer |
| Seal | Mechanical seal or packed seal – prevents material leakage |
| Nozzles | Coil medium inlet/outlet, material inlet/outlet, vent port, temperature sensor port, etc. |
