External Coil Reactor

The external coil reactor is a high‑efficiency chemical pressure vessel designed for heating and cooling chemical reactions. Unlike jacketed reactors, its heat‑exchange coils are welded externally on the tank shell rather than enclosed inside the vessel. It is widely adopted across fine chemical, pharmaceutical and new‑energy material industries under vacuum or pressurized working conditions.

Core Advantages

With no coils inside the tank, the inner wall remains smooth, preventing material buildup and simplifying cleaning procedures. It performs well when handling viscous fluids or media containing solid particles. External coils can withstand higher pressure from thermal media and achieve stable heat transfer. Besides, the coils avoid direct contact with process materials, lowering corrosion risks effectively. Half‑pipe coil structures are frequently selected for heavy‑duty applications.

Material & Safety Requirements

This equipment can be fabricated from stainless steel, carbon steel or high‑performance alloys. It is normally equipped with supporting stirring, feeding and discharging systems. Strict welding procedures and non‑destructive testing are indispensable. Reliable manufacturing guarantees long‑term, secure continuous operation in industrial production.
