Product Overview
The PM VSD Series Permanent Magnet Variable Speed Drive Screw Air Compressor integrates Permanent Magnet Synchronous Motor (PMSM) technology with Variable Frequency Drive (VFD) control. Through an intelligent control system, it precisely matches compressed air output with actual demand in real-time, achieving significant energy savings. This makes it ideal for industrial applications with fluctuating air consumption. The series offers multiple models covering a power range from 7.5kW to 250kW and working pressures from 0.7 to 1.25 MPa, meeting diverse industrial requirements.
PM VSD Series Permanent Magnet Variable Speed Drive Screw Air Compressors
Core Advantages
1. High Efficiency & Energy Savings
Utilizes Permanent Magnet Synchronous Motors (PMSM), delivering higher efficiency, especially under partial load conditions.
Combined with Variable Frequency Drive (VFD) technology for "on-demand air supply," eliminating energy waste during idle or unloading periods. Achieves comprehensive energy savings of 20-40%.
Features an optimized Twin-Screw Air End design for high efficiency across a wide pressure range.
2. Stable & Reliable Operation
Soft Start/Soft Stop functionality reduces impact on the power grid and minimizes mechanical wear, extending equipment lifespan.
Precise Closed-Loop Pressure Control ensures highly stable line pressure (fluctuations as low as ±0.01 MPa).
Operates with low noise and vibration under low-load conditions, improving the working environment.
3. Intelligent Control
Equipped with a Full-Color Touchscreen Controller, supporting multiple languages for real-time monitoring, energy consumption analysis, fault diagnosis, and early warning.
Supports Remote Monitoring & Data Management for centralized control of multiple units.
Adaptive control logic optimizes operational parameters, reducing manual intervention and enabling "unattended" operation.
4. Flexible Integration
Optional Integrated Unit Design with built-in refrigerant dryer, filters, and air receiver saves space.
Features Coaxial Direct Drive for a compact structure, high transmission efficiency, and maintenance-free operation.
