· In 1991, the first generation of Asymmetric Sectional Area Plate Heat Exchanger was developed, called BB series, which filled gaps in this field.
· The third generation of BB plate heat exchanger is also patented. It was designed according to thermal mixing theory with wider application scope and stronger adjustment ability.
A new generation (third generation) of Asymmetric Sectional Area Plate Heat Exchanger has all the advantages mentioned above, and it is specially designed for the working condition in which the flow rate of hot and cold medium is quite different. The cross-sectional area ratio of cold and hot flow channel is designed to be 2: 1, perfectly suitable for the condition in which the flow ratio of cold and hot medium is more than 2: 1.
