Advantages——Why pillow plate heat exchangers used more and more widely?——The reason lies in a range of advantages of pillow plate heat exchanger:——First of all, due to the open system and the relatively flat external surface, it is easy for cleaning and maintenance.——Secondly, welding pattern guarantees high turbulence, which creates high heat transfer coefficient and less fouling.——Thirdly, as no gaskets are required, it has high corrosion resistance, high pressure and temperature resistance.——Last but not least, according to different needs, different welding ways and plate materials are available to lower the cost and get the greatest benefit.
