Two-stage VSD screw air compressor with 30% improved efficiency, 12.5 bar

Product Specification

In demanding industrial operations where standard pressures fall short, high-pressure, unfluctuating compressed air is critical to sustaining heavy-duty production. The Bebaios 220kW/12.5bar Two-Stage Permanent Magnet Variable Frequency (PM VSD) Rotary Screw Air Compressor is an ultra-high-pressure powerhouse engineered for seamless performance in the most punishing environments. By dividing the massive 12.5-bar compression ratio across an advanced tandem dual-stage air-end, this system delivers an abundant volumetric airflow while drastically reducing internal component stress. Built for heavy manufacturing, deep-pit mining, and global petrochemical applications, it stands as a centralized air hub designed to eliminate downtime and maximize production yield.

Maximizing Financial Return Under High Loads: High-pressure compression is traditionally energy-intensive, with power costs commanding over 70% of an air compressor's lifecycle budget. Through the integration of near-isothermal dual-stage technology and a responsive PM VSD drive, this 220kW flagship configuration reduces electricity overhead by up to 30% compared to single-stage fixed-speed alternatives. The capital investment (CAPEX) is typically recovered through utility savings within 12 to 18 months, converting a heavy operational expense into a highly profitable industrial asset over its ten-year service life.

Tandem Dual-Stage Compression (Engineered for 12.5-Bar Workloads) Compounding air to 12.5 bar in a single stage creates extreme thermal and mechanical strain. Our dual-stage tandem structure splits this high pressure ratio across two distinct, optimized compression stages. This heavily reduces the radial and axial forces acting upon the premium bearings and rotors, ensuring minimized mechanical wear, lower failure rates, and a significantly extended overhaul cycle during continuous 24/7 heavy-duty runs.

Interstage Cool-Injection (Thermodynamic Peak Efficiency) A specialized high-capacity fluid-injection cooling matrix is integrated between the primary and secondary compression chambers. By cooling the compressed air before it enters the high-pressure second stage, the process achieves near-isothermal compression. This advanced thermodynamic layout delivers up to 15% more Free Air Delivery (FAD) per kilowatt, preventing high-temperature oil carbonization and lowering the specific power cost per cubic meter of air.
