The Rinheat MVR solution is based on the CS Evaporator body. MVR stands for Mechanical Vapor Recompression and is an evaporator driven by mechanical energy or electricity. The required pressure difference is created by a fan instead of steam or vapor. The MVR evaporator works with quite low energy demand as long as the boiling point rise is low.


Excellent for pre-evaporation and capacity upgrade
Minimizes the need for sweetening
Short vapor ducts enhance the efficiency

The MVR evaporator is a stand-alone unit and can be located separately because no large steam or cooling water piping is needed. In black liquor evaporation MVR is normally used as pre-evaporator.
