Why does a glass reactor require a circulating chiller and heater?

During experiments and production processes involving high or low temperature reactions, glass reaction vessels typically require a circulating chiller and heater to achieve precise temperature control.

The following situations explain why these two devices are needed:

Wide Temperature Range: When the reactor needs to operate over a wide temperature range, requiring both high-temperature reactions (such as up to 250 ℃ or above) and low-temperature reactions (as low as -80 ℃ or lower), it must be equipped with both a heater and a circulating chiller. A heater is used to heat the reaction medium, while a chiller is used for cooling to achieve the required reaction conditions.

High Temperature Control Accuracy: In experiments that require high temperature control accuracy, such as drug synthesis, fine chemical production, etc., the combination of circulating chillers and heaters can provide more accurate temperature regulation. Through closed-loop control systems, such as PID control, the temperature inside the reactor is maintained to have minimal fluctuations near the set value.

Continuous production or complex reaction processes: In complex reaction processes that require continuous production or involve multiple temperature stages, rapid response and precise adjustment of heating and cooling equipment have become particularly important. The integrated use of chillers and heaters can quickly adjust the temperature of the reaction vessel to meet the process requirements of different stages.

Thermal Management: A large amount of heat may be generated during the reaction process, and the chiller needs to remove excess heat in a timely manner to prevent overheating. At the same time, the heater can provide necessary heat supplementation in the early stage or low-temperature reaction stage.

Improving efficiency and product quality: Accurate temperature control can optimize reaction rate, improve product yield and purity. The combination of chiller and heater can significantly improve experimental or production efficiency and product quality.
