VR Series Steam Roots Compressor – High-Efficiency Roots-Type Steam Booster for Industrial Applications
Key Features of VR Series Steam Roots Compressor
1. Specially Designed for Steam Handling
Unlike standard air blowers or gas compressors, the VR Series Roots Compressor is specifically designed to transport clean saturated steam without condensation or leakage. All internal components are thermally stabilized and corrosion-resistant, ensuring long-term operation in high-humidity, high-temperature environments.
2. High Sealing Performance
Advanced shaft seal systems (mechanical seals or labyrinth + oil seal combinations) are adopted to prevent steam leakage, ensuring safe and energy-efficient operation even under fluctuating inlet pressures.
3. Superior Energy Efficiency
The Roots mechanism ensures high volumetric efficiency with minimal internal backflow. Combined with precision-machined three-lobe rotors, the VR Series achieves low energy consumption and stable discharge pressure, making it suitable for continuous-duty applications.
4. High Temperature and Pressure Resistance
Capable of handling inlet steam temperatures up to 200°C and pressures up to 98kPa (single stage), the VR Series is built for steam compression and recovery systems, often used in waste heat recovery and vapor recompression (MVR) processes.
5. Maintenance-Friendly and Robust Design
Modular construction allows for easy maintenance and part replacement
The use of oil-lubricated gears and grease-lubricated bearings ensures long bearing life
Optional water jacket available for housing cooling when required
