What is a MVC Evaporator?
A Mechanical Vapor Compression (MVC) evaporator is an energy-efficient evaporation system that uses mechanical energy to compress vapor, raising its temperature and pressure so it can be reused as a heating source. This technology significantly reduces energy consumption compared to traditional evaporation methods.
Memva MVC evaporators are designed for industrial applications where concentration, volume reduction, or Zero Liquid Discharge (ZLD) is required. Our systems offer superior energy efficiency, low operating costs, and high reliability.
How MVC Technology Works
The MVC process involves these key steps:
- Feed solution enters the evaporator and is distributed over heat exchanger tubes
- Vapor generated from boiling is mechanically compressed, increasing its temperature
- Compressed vapor returns to the heat exchanger as the heating medium
- Concentrated solution is discharged from the bottom of the evaporator
- Condensed vapor (distillate) is collected as high-purity water
Memva MVC Technology Features
Memva's advanced MVC evaporators incorporate proprietary design features that maximize efficiency, reliability, and operational flexibility for diverse industrial applications.
