Heating and Cooling Circulation Device for Jacketed Reactors

When used in jacketed reactors, heating and cooling circulation device can provide accurate and wide-range temperature control to meet the needs of hot and cold changes during the reaction process.

Advantages of heating and cooling circulation device:

1. Flexible temperature control: It integrates heating and cooling functions, and can quickly and accurately adjust the temperature in the reactor within a large temperature range to adapt to complex reaction conditions.

2. Efficient heat exchange: Through the jacket design, the circulating medium (usually heat transfer oil or water) circulates on the outer wall of the reactor to achieve efficient heat transfer and reduce energy loss.

3. Temperature uniformity: The circulation system ensures uniform temperature in the reactor, avoids local overheating or overcooling, and improves the uniformity of the reaction and product quality.

4. Safety and stability: It is equipped with various safety protection devices, such as over-temperature alarm, pressure control, etc., to ensure safe and reliable operation.

5. Automatic control: Modern systems are mostly integrated with automatic control systems, which can preset temperature curves and automatically adjust heating or cooling rates, facilitating the management of complex experimental processes.

Application examples of heating and cooling circulation device:

Synthesis of fine chemicals: In complex organic synthesis that requires precise temperature control, to meet the reaction temperature requirements at different stages.

Pharmaceutical process: In the synthesis of pharmaceutical intermediates or active ingredients, ensure that the reaction conditions strictly meet the requirements to ensure product quality and yield.

Polymerization reaction: When synthesizing polymer materials, it is necessary to switch heating and cooling at different stages to control the polymerization rate and molecular structure.

Biochemical engineering: In enzyme-catalyzed reactions or microbial cultures, maintain a suitable temperature environment to promote the development of biological activity.

Material science research: In the synthesis and characterization of new materials, control reaction conditions and study the effect of temperature on material properties.
