As we all know, the plate and shell heat exchanger is the first choice heat exchanger with high temperature and high pressure resistance, combining the advantages of the plate heat exchanger and the tubular heat exchanger. Moreover, the plate and shell heat exchanger has been developing in the direction of larger volume and higher heat exchange efficiency. Is there any difference between the two? Let me explain today.

| Temperature difference | (min.) 1 ? | (usually above) 10 ? | |
The above is the comparison between the two. At present, it is the most widely used. The plate heat exchanger is generally used by everyone. No matter what industry, as long as it is suitable for you, it is the best. However, the plate heat exchanger exists as a new type of heat exchanger. It has high heat exchange efficiency unmatched by traditional heat exchangers and a low floor area. If considering the economic cost, it is still necessary to choose a plate heat exchanger.
The plate and shell heat exchangers manufactured by Qingdao reapter Heat Exchange Equipment Manufacturing Co., Ltd. have high efficiency and stable quality. They can be designed and manufactured according to different working conditions and have consistent quality.
