MVR - Evaporators
The C. E. Rogers Company has designed, installed and successfully commissioned many Mechanical Vapor Recompression (MVR) evaporator systems for processors with access to a favorable electrical rate structure. The basis for MVR design is the use of a mechanical compressor instead of a steam thermocompressor. This mechanical compressor is most commonly driven with an electric motor. Utilization of the mechanical compressor substantially reduces steam requirements as well as cooling water demand.

Evaporation by means of mechanical recompression can be more cost effective than TVR evaporation. The MVR design used for pre-concentration (before entering an evaporator for high solids concentration) in place of a membrane system is highly efficient and requires very little maintenance. The high efficiency of a C. E. Rogers MVR Evaporator System can make an important contribution to your energy savings program.

With an MVR evaporator system efficiencies can run as high as 200 lb of water evaporated per kwh (roughly the equivalent of 25 lb water evaporated per lb steam with a TVR evaporator).

C. E. Rogers MVR Evaporator Systems can be designed for rates from under 20,000 PPH to over 150,000 PPH. Contact us for more specific information.
