Propellent Plate evaporators climbing-falling film evaporation, the materials pass between the plates and are heated by steam to evaporate. Unique asymmetric large porthole of the Propellent evaporator ensures the most efficient heat transfer. Strong evaporation effect and large heat transfer coefficient depend on Propellent’s special design plate. The premium patterns of the plate make the fluid flow arise intensive turbulence. Operating very convenient with the compact structure and small size, and easy to observation.
