Multiple effect evaporators treat high volume flow rates, especially when a low cost heat source is available (hot water, vapor, etc.).
We provide multiple-effect concentrator evaporators driven by hot water or steam from an external circuit as sources of energy, which enables the use of residual heat flows.
Units can be 1 (single-effect evaporator), 2 (double-effect evaporator) or 3 (triple-effect evaporator) staged and heat transferred to the evaporated product is fully recycled during the following stages, producing a “cascading” effect. Finally, the distillate is condensed by means of a cooling tower with low consumption of water.
These multiple-effect vacuum evaporator units are designed to support up to 3 stages, so as to double and even triple the production without involving an increase of energy supply.
We supply two configurations:
In addition, we supply single-stage equipments, with internal scraper, series Envidest LT VR, for paste and fouling fluid treatment.
