Mechanical Vapour Recompression (MVR)

Mechanical compression raises the temperature and vapour pressure, allowing its reuse and a significant improvement in the energy performance of a facility.

Multiple applications

Mechanical Vapour Compression (MVC) has several applications:

  • The conversion of a single-effect or multiple-effect evaporator into Mechanical Vapor Recompression
  • Steam recovery for reuse in another workshop

MVC applications are multiple and are systematically the subject of specific studies conducted in collaboration with your team to define the most relevant patterns.

Investment return

With an investment return of 1 to 3 years, Mechanical Vapor Compression installed on your existing units will sustainably reduce your operating costs.

The modifications proposed by FE by France Evaporation have no impact whatsoever on processes or capacity.

High level technology

When properly sized and installed, CMV/RMV systems offer remarkable reliability. We have been using this technology for over 20 years, and the compressors we use require very little maintenance, with extremely low servicing costs.

To ensure this reliability, we use:

  • A largely sized separator, which allows maximum separation of evaporation vapour and avoids provoking product droplets in the MVR, in order to ensure the fan’s lifespan.
  • In addition to the separator, our facilities are equipped with a mist eliminator that cleans evaporation mist and removes any remaining product droplets to protect the blower mechanism. It also prevents foaming.
  • At the outlet of the scrubber, a demister stops any droplets.
  • Many additional securities to monitor and ensure the proper functioning of the installation: levels, temperatures, vibrations, etc.
