Spray Dryer | Multi Effect Evaporator Manufacturer and Supplier – Shachi Engineering

MVR Evaporator

Mechanical Vapor Recompression Evaporator Manufacturer in India

Concentrate liquids and effluents with much lower steam consumption. Shachi’s MVR Evaporator systems reuse the vapour generated during evaporation as the heating source for the process. This helps reduce dependency on fresh steam, lowers operating cost and makes evaporation more energy-efficient for continuous industrial operations. Designed for chemical, pharmaceutical, food, textile and wastewater applications, Shachi MVR systems are engineered around your feed, concentration target, fouling behaviour, utility availability and plant layout.

MVR Evaporator

Trusted for Critical Evaporation Applications

MVR evaporation is not only about saving steam.
It is about designing a stable system that works every day with the right compressor, heat transfer area, circulation pattern, instrumentation and process control.
Shachi brings process engineering, thermal design, automation and commissioning experience together to deliver MVR systems that are practical to operate and easier to integrate into new or existing plants.

Advantages of MVR Evaporator

Wide capacity range

Lower Steam Consumption

MVR reuses secondary vapour as heating media, reducing the need for continuous external steam during operation.

Precise Control

Lower Operating Cost

By reducing fresh steam and cooling water requirements, the system helps bring down daily evaporation cost.

Automation & Control

Low-Temperature Evaporation

Suitable for heat-sensitive products and effluents where controlled evaporation temperature is important.

Flexible layouts

Compact & Energy-Efficient Design

A well-designed MVR system can reduce utility load and plant footprint compared to conventional evaporation systems.

FAQs – MVR Evaporator

An MVR Evaporator is an evaporation system that compresses the vapour generated during evaporation and reuses it as heating media. This reduces fresh steam consumption and improves energy efficiency.
A conventional evaporator depends heavily on external steam. An MVR system recycles its own vapour after compression, which reduces the need for continuous fresh steam during operation.
No. MVR suitability depends on feed composition, boiling point elevation, fouling nature, viscosity, scaling tendency, evaporation load and utility cost. A technical evaluation is required before selection.
MVR is useful where evaporation load is high and steam cost is a major operating expense. It is commonly considered for chemical, pharmaceutical, food, textile and ZLD applications.
MVR generally requires steam or another heat source during start-up. Once the system stabilizes, the requirement for fresh steam can reduce significantly depending on the process design.
The compressor, blower or fan is selected based on vapour flow, pressure rise, temperature lift and process requirement. Correct compressor selection is critical for stable and efficient operation.
Yes. MVR can be integrated into ZLD systems to reduce steam consumption during evaporation. It can be combined with crystallizers, centrifuges, ATFDs or dryers based on the final treatment requirement.
Basic details include feed flow rate, feed composition, inlet concentration, final concentration target, operating hours, available utilities, fouling tendency, temperature sensitivity and downstream process requirement.
