Apr 01, 2020 · A device known as glass reactor jackets combats this disadvantage so that jacketed glass reactors can perform cooling and heating processes more efficiently. Glass reactor jackets are used to circulate heat transfer liquids on both the interior and exterior of the jacket to increase or decrease the heat to and from the process.
Reactor heating/cooling systems are designed by the following : Maintain high heat transfer coefficients in the reactor to promote increased rate of heat transfer. Maintain low temperature differential between reaction mixture and thermic fluid in jacket to minimize loss of yield in case of heat sensitive products.
Jacketed glass reactor is one of the important types of glass reactors. It is a compartment designed to control the temperature of its material, using a cooling or heating "shell" around the reactor through which a refrigerant or heating fluid circulates.The housing can allow a uniform heating trade between the circulating fluid and the vessel joints.

20L Process Reactor Sytems. . Reactor Jacket Graduation Scale on Both Sides Large Detachable Drain: . Entire body of the flask is jacketed and has two hose connections for circulation of heating or cooling liquid. Indentations increase agitation of the contents of the flask during stirring.
Cooling and heating can be applied directly to the vessel by heat transfer surfaces in the vessel exterior (e.g., jackets) or interior (e.g., coils) or indirectly via a process recirculation stream. Heat exchangers are used for some jacket temperature control systems and for all process recirculation temperature control systems (discussed in .
Circulating liquid can be filled into the jacket to heat or cool materials inside. Triple wall glass reactor with two jackets, the inner jacket is for circulating liquid, and the outer layer should be pumped to vacuum condition for thermal insulation. .
