Maximized energy efficiency with MVR
Reduce carbon emissions through smarter evaporation
Evaporation is a method used to remove water from a liquid to concentrate it. In everyday life, we encounter products that have undergone this process, such as milk powder, juice concentrate, and salt. The method is based on vaporization and is central especially in the food industry, pulp and paper industry, chemical, and pharmaceutical industry. Evaporation can also be used to recover valuable by-products from waste streams.
Mechanical Vapor Recompression, commonly abbreviated MVR, is a modern and proven technology for evaporation. By introducing highly efficient MVR technology, both energy consumption and carbon dioxide emissions are often reduced, resulting in significant cost savings.
The uniqueness of MVR technology lies in fully utilizing the energy in the steam, achieving maximum energy efficiency. By compressing the steam removed from the product and returning it to the evaporator as an energy source, energy consumption can be reduced by up to 97%*.
Introducing MVR also means an electrification of the evaporation process, and at the same time, the need for steam is eliminated. Modern MVR systems also have high availability and reliability.

Benefits of MVR-evaporation
Reduce CO2 emissions and achieve sustainability goals
Free up steam capacity through increased energy efficiency
Lower energy costs and strengthen competitiveness
Applications of MVR technology
More and more industries are using MVR technology in their evaporation, here are some of the most common applications.
Customers using Adven’s MVR evaporation
Evaporation is critical for us to be able to utilize the nutrients contained in our reject waters. Adven’s evaporation solution removes some 90 per cent of the water, which makes the fertilizer cost-effective to transport and easier for farmers to handle.
Visit Adven’s MVR evaporation plant
Adven’s MVR evaporation solution is part of IFF Finnfeeds Finland’s production process in Naantali, Finland. Visit the evaporation plant and turn the image 360° in any direction.

MVR for heat pump solutions
MVR technology can also be employed to harness waste heat or to raise the temperature of hot water and steam in an industrial process. The principle is the same as conventional heat pumps, with the difference that they use water (in the form of steam) as the working medium, instead of for example ammonia.
This allows the technology to be used for higher temperatures compared to conventional heat pumps and can deliver heat up to 200 °C. By using water as the working medium, one can also avoid environmental and safety risks associated with handling chemicals.
