Our tubular falling film evaporator is well proven and mechanically reliable. An innovative arrangement with more efficient horizontal flow droplet separators provides a smaller footprint than other falling film designs. This is advantageous when adding additional units in an existing evaporation train and space is limited.
Excellent condensate segregation and high evaporation capacity in a single vessel are two of the other major benefits of our falling film evaporator design.
Valmet’s tubular falling film evaporators are currently serving in many of the world’s most profitable pulp mills.
Like in all Valmet evaporators, the tubes used as heating surface are mechanically reliable and provide exceptionally long service life. And the efficient design of the horizontal flow droplet separators helps to ensure an even heat transfer and high performance.
Valmet’s Tube evaporator design has been refined and upgraded over many years, making it the ideal choice for modern evaporation plants.
