    In the chemical industry, it is mainly used for the cooling of chemical reaction kettle (chemical heat exchanger) to timely take away the ordinary heat caused by chemical reaction, so as to achieve the purpose of cooling (cooling), so as to improve product quality.

    In the pharmaceutical industry, it is mainly used for the control of temperature and humidity in the consumption workshop and the removal of reaction heat in the process of consuming API.

    In the consumption process of electronic components, the components need to be maintained or cooled at a specific temperature, and the performance parameters of electronic components can be controlled in the design state.

    Widely used in low temperature reaction fields in chemical, pharmaceutical, biochemical and other industries;

    Supporting extraction, distillation, reaction kettle...used for filtration, crystallization...reaction.
