| Same | They are all new types of heat exchange equipment, with high heat exchange efficiency, very small footprint, easy to remove and clean, and a great deal of energy saving. By changing the material of the plate, it can resist the corrosion medium. | ||
| The most important heat exchange element-plateis same, even if theformis different, but theheat exchange speedis similar | |||
| Difference | plate | Stacked together;Exposed | Welded together to form a plate pack;Plate in the shell |
| gasket | Seal with gasket | Plate packs are welded together without the need for gaskets | |
| High temperature and pressure | Tolerate | More Tolerate | |
| Fouling coefficient | low | lower | |
