Vehicle high temperature and high humidity test vehicle anti-aging performance
On test benches in the automotive industry, accurate temperature simulation is critical. From the time of the test, the air temperature in the test chamber has always been maintained at 45 ℃, which is equivalent to the hottest area of the Flaming Mountains in Turpan, Xinjiang, China. Ultra-high temperature environments cause all automotive components, from control electronics to gaskets and load-bearing elements, to experience severe temperature fluctuations that, in addition to mileage, str...

What is the function of high temperature heat transfer fluid system？
The high temperature heat transfer fluid system adopts a fully closed circulation system, so that there is no oil mist during high temperature operation, and high temperature refrigeration can be realized. It is the temperature control equipment used in many industries at present. 1. High temperature heat transfer fluid system is used with most experimental equipment, such as rotary evaporator, uniform temperature, constant liquid environment. It is forbidden to store in the open air, avoid ...

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...

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...
