2019/05Plate cleaning and protection
Keeping the sheets clean is one of the important conditions for maintaining a high heat transfer coefficient. Between the plates, the medium moves along the narrow and meandering flow path. Even if a relatively thick scale laye...+ More

2019/05What are the characteristics of brazed plate heat exchangers
(1) small and efficient: because the heat transfer process is carried out in a 0.5mm thin plate, it has a high heat transfer efficiency, the heat transfer efficiency after the couplet is more than 90%. (2) Dust is difficult t...+ More
