Mechanical Vapour Recompression (MVR) Evaporator Manufacturers

Thermosag is a leading mechanical vapor recompression (MVR) manufacturer in India, specializing in providing innovative and efficient solutions for thermal separation processes. With a focus on energy efficiency and environmental sustainability, Thermosag has established itself as a trusted name in the industry.

What is Mechanical Vapour Recompression?

As the name suggests, mechanical vapor recompression technology involves the use of a mechanical compressor that recompresses the vapor of an MVR evaporator to a higher pressure. It functions as a heat pump, adding more energy and increasing the temperature gradient to the vapor.

Our technology offers a whole gamut of benefits ranging from reduced specific energy consumption, low operational costs, seamless evaporation of the product owing to low-temperature differences, simplicity of the process, and top-notch partial load behaviour.

Product Overview

Evaporation, a vital thermal separation process, is widely used in chemical, pharmaceutical, agrochemical, specialty chemical, dye, food & beverage, salt, and environmental industries. To cut energy costs and boost sustainability, plants evolved from multiple-effect systems to thermal vapor compression and now MVR, reducing fossil fuel use, water loss, and TOE in production.

MVR Working Principle

Centrifugal Turbo Recompressors as MVR

Centrifugal recompressors are generally used in evaporation plants function with 8-20 degC temperature differences. These are also continuous flow machines with a speed range of 10,000 and 35,000 RPM. There is a spiral type housing in these compressors with an axial suction nozzle and a open rotating impeller.

Impellers are manufactured using titanium alloys. The high rotating speeds and the resulting forces necessitate the shape and stability of impellers and hence the construction. 

A single-stage turbo compressor helps achieve the compression ratio of more than 2 with a volume flow range of 1 and 140 m3/second.

Centrifugal turbo recompressors are designed with state-of-the-art construction and technology. Their supremacy to the centrifugal fan, Centrifugal Blower and rotary blower recompressors is unquestionable on account of a plethora of reasons and advantages. Stable performance, best cost-performance, optimum utilization of the equipment functioning, and perfect balance of investment and output ratio are some of the many reasons why centrifugal turbo compressors outperform other type of MVR’s.
