Technical details and manufacturing context for Heating/Cooling Jacket

Definition
A heating/cooling jacket is an essential part of a reactor module that provides precise temperature control by circulating heating or cooling fluids through an enclosed space surrounding the reactor vessel. It maintains optimal reaction conditions, prevents thermal runaway, and ensures consistent product quality in chemical processes.
Working Principle
The jacket operates by circulating a thermal fluid (such as water, oil, or steam) through the space between the reactor wall and the jacket shell. Heat transfer occurs through conduction across the reactor wall, with temperature controlled by adjusting fluid flow rate, temperature, or switching between heating and cooling circuits.
Common Materials
Stainless Steel 316L, Carbon Steel, Hastelloy
