Product Details

Mazda’s Thermal Vapor Recompression (TVR) Evaporator System is an energy-efficient solution that reduces live steam demand by recompressing part of the generated vapor and reusing it as a heating medium. This process delivers up to 50% savings in steam consumption while ensuring stable, reliable performance with minimal maintenance. Positioned between Multiple Effect Evaporators (MEE) and Mechanical Vapor Recompression (MVR), TVR offers industries the benefits of strong energy savings, simple operation, and a lower investment cost compared to MVR systems — making it a smart choice for plants focused on efficiency and sustainability.

Advantages

  • Provides significant energy savings by reducing live steam demand.
  • Ensures low operating costs with no moving parts and simple operation.
  • Offers a lower capital cost than MVR while delivering improved steam economy.
  • Compact and easy to integrate with existing evaporation systems.
  • Reliable and low-maintenance with long service life.

The TVR system operates by mixing a portion of the vapor generated in the evaporator with high-pressure motive steam inside a thermocompressor. This raises the pressure and temperature of the vapor, enabling it to be reused as the heating medium in the heat exchanger. The process minimizes fresh steam consumption while maintaining efficient evaporation, with steam economy reaching 1.3–2.0 kg of water per kg of steam. When combined with MEE, efficiency can be pushed even higher.
