Generally speaking, the temperature of most chemical reactions will start at room temperature and may need to be gradually increased to promote the reaction. Some reactions need to be carried out within a specific temperature range. For example, hydrothermal reactions are often used in pharmaceutical chemistry. The required reaction temperatures are generally relatively high and the reaction times are relatively long.

In some special pharmaceutical processes, such as solid-phase synthesis and liquid-phase synthesis, the reaction temperature may need to be precisely controlled through the use of heaters, thermostats or cooling equipment. For some specific pharmaceutical reactions, such as biological enzyme-catalyzed reactions, temperature control may be more complex and precise.

The high temperature range in the chemical industry is a very important link and needs to be strictly controlled. Reaction temperatures that are too high or too low may lead to out-of-control reactions or poor product quality. During storage and transportation, high temperature environments can easily cause product degradation or deterioration, and may even cause safety accidents. Generally speaking, these reactions need to be carried out at high temperatures above 100°C. For example, some polymerization reactions usually need to be carried out at high temperatures of 150-200°C, while the synthesis of some polymer compounds needs to be carried out at high temperatures above 250°C.

There are 17 types of chemical processes. In order to achieve quality, yield and safety, temperature control is basically indispensable. We at LNEYA have been deeply involved in the pharmaceutical and chemical industry for 16 years. The low-temperature water coolers, high-temperature circulators, and dynamic temperature control systems we produce are widely recognized and used by customers. The cooling and heating equipment uses thermal oil as the medium and the fluid temperature is controlled. The closed cycle uses fluid media to control the constant temperature of the reaction vessel or reaction materials, with high temperature accuracy. The system intelligently records the temperature change curve in real time, which facilitates the operator’s later data summary and analysis, and has established a large number of in-depth cooperative enterprises.
