SED - Spray Engineering Devices Ltd Limited
MVR Fan

Efficient. Sustainable. Engineered for Maximum Thermal Recovery.

Our high-efficiency SED’s high-efficiency Mechanical Vapor Recompression (MVR) system, the   EffiFlow Turbo Fan , is designed to dramatically reduce energy consumption and operational costs in industrial evaporation, distillation, and drying processes. By capturing low-pressure vapor, compressing it, and reusing its thermal energy, the fan minimizes the need for external steam, delivering significant cost savings and improving process efficiency.

Optimized for systems such as Low Temperature Evaporators (LTE®) and Plate Type Falling Film Evaporators, the EffiFlow Turbo Fan enhances evaporation rates, improves product quality, and supports higher throughput-making it a critical component in sustainable industrial operations.

How it Works

Step Icon

Evaporation and Vapor Capture

Water or solvent vapor generated during evaporation is collected rather than vented or externally condensed.

Step Icon

Vapor Compression

The captured vapor enters the EffiFlow Turbo Fan, where high-speed impellers compress it, increasing both pressure and temperature.

Step Icon

Thermal Energy Reuse

The high-temperature vapor is redirected back into the evaporator as a heat source, replacing or supplementing external steam.

Step Icon

Latent Heat Recycling

The system utilizes the vapor’s latent heat to minimize energy input requirements and maximize thermal efficiency.

Step Icon

System Efficiency and Stability

Continuous recompression ensures steady heat delivery, promoting uniform evaporation rates and reliable process control.

Step Icon

Energy and Resource Optimization

Reduced fresh steam and cooling requirements lead to lower energy costs, minimized utility load, and improved sustainability.
