Mechanical Vapor Recompression

Use already used energy again sensibly for processes.

In the mechanical vapor recompression, the vapors are compressed by an electrically operated compressor and used again to heat the evaporator. Depending on the application (boiling point increase, heat transfer), one- or two-stage turbo-ventilators or turbo-compressors are used as heat pumps.

Evaporation of liquids

Here, the process steam (vapor) arising in the industrial processes is lifted to a higher temperature and thus higher energy level with a centrifugal fan (mechanical vapor compressor, MBV) and then returned to the process as fresh heating steam. The energy contained in the steam is not lost, only the energy required to increase the temperature must be additionally applied. Since the dramatic increase in energy costs in recent decades, efforts have been made to reduce the consumption of fossil fuels and CO2 emissions, as well as to reduce the high levels of steam consumption for these processes to date. With mechanical vapor recompression, these efforts can be achieved because it is a cost effective and reliable process for evaporation, distillation, crystallization and drying.

Facility Planning

GIG Karasek specially dimensioned the evaporation plant for its coordinated needs and requirements. The process conditions are of crucial importance for the correct dimensioning. Optimum dimensioning for our customers results in minimal investment costs and maximum energy efficiency
