This heat exchanger utilizes a double tube sheet structural design, where the tube side and shell side are linked via their respective tube sheets. This design reduces the risk of cross-contamination to a minimum, facilitates timely detection of leakage risks, and ensures safe production. Owing to its compact size and high heat exchange efficiency, it is widely applied in industries such as pharmaceuticals, chemicals, electronics, beverages, and semiconductors—especially in on-site scenarios with insufficient space, which further highlights the product’s excellent performance. Its ultra-compact size and superior heat exchange performance not only provide users with efficient heat transfer but also reduce installation space requirements for users, while lowering installation and maintenance costs.
