Jacketed Reactor Heating & Cooling - Sigma Thermal

Jacketed Reactor Heating & Cooling. In reactors, heating and cooling jackets are used to remove heat from exothermic reactions or provide the needed heat required to produce the desired endothermic reactions. Steam jackets that operate at high pressures can pose safety issues, especially when hazardous chemicals are being used within the reactor.
