Best VR Series Steam Roots Compressor – High-Efficiency Roots-Type Steam Booster for Industrial Applications Manufacturer, Suppliers
The VR Series Steam Roots Compressor is a specially engineered positive displacement compressor designed for handling clean and saturated steam. Developed with advanced sealing and thermal-resistant technology, the VR Series offers stable performance under high-temperature and high-moisture environments, making it ideal for industrial processes requiring steam boosting, circulation, or recovery.
Built by our company using state-of-the-art materials and over 40 years of fluid machinery expertise, the VR Series is trusted by industries such as chemical processing, power generation, pharmaceutical, textile, food sterilization, and more.
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
