Overview of the 200 m³/day Plate Heat Exchanger MVR Evaporator
The TV200-PHEMVR-EC-2STDU25 is an advanced Plate Heat Exchanger MVR Evaporator System designed for industrial-scale evaporation and concentration.
It applies Mechanical Vapor Recompression (MVR) technology combined with a Plate Heat Exchanger (PHE) to recover and reuse thermal energy efficiently.
The system is custom-engineered and manufactured by TVTS according to each factory’s operational and process needs, with design capacities ranging from 50 to 200 m³/day.
This is a made-to-order system, not a standard product, ensuring complete adaptability to each industrial application.
The unit can be integrated or upgraded with a crystallization function, allowing users to concentrate solutions to high solids, recover purified condensate, and produce crystalline solids as final output.
1. Working Principle of the MVR Evaporator with Plate Heat Exchanger
The MVR Plate Heat Exchanger Evaporator operates on a closed-loop vapor compression and heat recovery process.
During operation, vapor generated from the solution is compressed by the mechanical vapor compressor to a higher pressure and temperature.
This compressed vapor is then sent back to the plate heat exchanger (PHE) to provide the necessary heat for continuous evaporation.
Because the system recirculates latent heat, it consumes only a small amount of external energy—mainly for the compressor and circulation pump.
This design results in exceptional energy efficiency, minimal steam use, and high condensate recovery.
2. Advantages of the TV200-PHEMVR-EC-2STDU25 Plate Heat Exchanger MVR Evaporator
🔹 Maximum Energy Efficiency
The unit uses recycled heat from compressed vapor, eliminating the need for an external steam source.
It operates at only 40–60 W per liter of condensate, making it one of the most efficient evaporation technologies available.
🔹 High and Stable Evaporation Performance
Continuous compression and heat exchange maintain consistent temperature and pressure, ensuring steady concentration rates and long-term operational stability.
🔹 Crystallization Integration Option
The system can be equipped with a crystallization module, enabling salt or solid recovery from concentrated liquids — ideal for Zero Liquid Discharge (ZLD) operations.
🔹 Compact, Easy-to-Maintain Design
The plate heat exchanger minimizes installation footprint, allows quick disassembly, and simplifies cleaning compared to traditional shell-and-tube designs.
🔹 Premium Construction Materials
Built from Titanium or Duplex 2507, the unit offers outstanding corrosion resistance, suitable for saline, acidic, or chemical wastewater.
3. Limitations of the MVR Plate Heat Exchanger System
⚙️ High Initial Investment: The mechanical compressor is complex and costly, raising the system’s upfront investment.
⚙️ Technical Maintenance Requirements: Skilled technicians are required for compressor calibration and control system maintenance.
⚙️ Temperature Limitations: Efficient operation occurs above 60°C, making it unsuitable for low-temperature evaporation processes.
⚙️ Extended Start-Up Time: Initial vapor generation consumes significant energy; hence, continuous operation is preferred for best performance.
