MVR is a mechanical vapor recompression (MVR) technology. Recompression is the use of secondary steam and its energy produced by the evaporation system itself to transform low grade The steam of the compressor is upgraded by the mechanical work of the compressor to a high-grade steam heat source. This cycle provides heat energy to the evaporation system, thereby reducing the demand for outside energy as an energy-saving technology.
In order to make the manufacture of the evaporation device as simple as possible and easy to operate, centrifugal compressor and Roots type compressor can be used. These machines in 1:1.2 to 1:2 compression ratio in the range of its volume flow is high.
