Various reactors and materials use PLC temperature control system
The PLC temperature control system is used for the lifting and constant temperature control of glass reactors, metal reactors and bioreactors, especially for heat exothermic control in the reaction process. The heat transfer oil in the jacket of the reactor is heated, and the heat energy is indirectly transferred to the heating kettle in the material, so as to control the heating temperature of the reaction material. The industrial temperature control technology of the equipment has the advan...

There are usually three ways to control the temperature of laboratory reactors
1. Manual control: Manually operate the knob on the front of the reactor controller.2. Control by PC: The PC and the controller are connected by a network cable, and the operation is carried out on the PC.3. Controlled by thermostat: Silicone oil is heated through the thermostat, and the thermostat naturally has a temperature control function. Although the thermostat heating limit (usually 250°C) is not as high as that of electric heating (can be as high as 400-500°C), the thermostat rises a...

What are the applications of Industrial temperature control machine chillers?
Industrial temperature control machine chillers are divided into oil-cooled and water-cooled according to the temperature and medium. The medium used is different for different temperatures, water can be selected for normal temperature, heat transfer oil for high temperature, and refrigerant for low temperature. According to the different cooling methods, it can be divided into air cooling and water cooling. Consider the ambient temperature of the industrial temperature control machine chil...

Temperature control instructions for stainless steel reactors and glass reactors
Reactor is a kind of reaction equipment in industrial production. It generally needs to be refrigerated or heated. Whether the temperature is suitable or not directly affects its reaction effect. Therefore, if conditions permit, it is generally equipped with a reactor temperature control device. The temperature control device of the reaction kettle uses the conversion of heat conduction oil to heat the material to be heated. Inferior heat conduction oil has a short service life and is prone ...

What are the conditions for the decarboxylation reaction? How to control the temperature of heating?
The decarboxylation of aromatic acids is easier than that of fatty acids. For example, benzoic acid can be decarboxylated by adding a little copper powder as a catalyst in quinoline solution and heating. When a strong electron-withdrawing group is attached to the α-C of the carboxylic acid, heating can make it decarboxylate more smoothly. For example: when the ortho-diaromatic organic acid is heated, it is easy to remove a carboxyl group, but when the temperature is low, an acid anhydride wi...

Disadvantages and advantages of general heat transfer oil heating circulation system
The heat conduction oil heating circulation system adopts a fully closed loop structure to directly act on the heat energy to the heated medium. Its advantages are: (1) Due to the continuous renewal of the heat transfer surface, the heat loss is small; (2) The temperature field distribution state of the medium can be changed during operation; (3) Multiple units can be used in parallel. The closed circulation system has a wide range of applications, such as various boilers, industrial furnaces...

Selection of ultra-low temperature chiller supporting the glass reactor
In order to achieve an economical ultra-low temperature environment for glass reactors, many customers will not choose multi-stage compressor refrigeration equipment with more than two stages, but use liquid nitrogen. The cost of liquid nitrogen is low, and this refrigeration method is welcomed by some users, both in experiments and in production. However, due to the low boiling point of liquid nitrogen (minus 195.8°C), the latent heat is small and it is easy to evaporate. There are also bi...
