The JLGH type high-efficiency tube and tube heat exchanger is a type of insert that can generate radial flow in the heat exchange tube to enhance heat transfer inside the tube. The contribution of Julong Equipment Company is to use a special process to improve the accuracy of the insert to the extreme. Its precision and economy are reflected in high viscosity systems and other systems. The company has developed inserts that are suitable for both high viscosity systems and ordinary fluids with low pressure drop and economy. The company can be responsible for tailoring according to customer process requirements (i.e. process calculation and design). At present, this product has replaced foreign imports in the ABS and PS industries, such as Tianjin Daguhua, Shanghai Huayi, Changchun Gaoqi, etc. It has also been gradually promoted and applied in new material industries such as polyester, polylactic acid, and cellulose in China, such as Zhejiang Haizheng, Tongji University Tongjieliang Company, Nanjing Hongbaoli Company, etc.

JLGH-II non tubular high-efficiency heat exchanger is based on the principle of static mixing. According to the physical properties and reaction conditions of different reaction systems, different forms of mixing elements are used in the pipeline to strongly shear, disperse, and mix the reactants, and provide a larger reaction area and heat exchange area, so as to achieve the optimal concentration and temperature uniformity of the reactants and narrow residence time distribution;
