The latest 22 kW TVD+ series permanent magnet two-stage variable-frequency screw air compressor with innovative design

The TVD+ series 22 kW permanent magnet two-stage variable-frequency screw compressor employs dual energy-saving technologies—two-stage compression and permanent magnet frequency conversion—with an overall efficiency 15–20% higher than that of Class 1 units, making it the ideal solution for energy-efficient upgrades and air source enhancement in medium-sized manufacturing facilities.

1.  The 1:10 tapered sleeve features a direct-drive design with over 95% contact area, ensuring high transmission accuracy and smooth operation without looseness.

2. The IE5 oil-cooled permanent magnet motor, equipped with intelligent frequency conversion control, achieves an efficiency of up to 96%, delivering significant energy savings.

3. The external oil tank features a high-capacity design with low pressure differential, long service life, and easy maintenance.

4. It operates with ultra-low noise levels as low as 70–72 dB and features IP65 protection rating for dust-prone and humid environments.

5. Comprehensive motor protection (phase loss/overload/unbalance/over/under-voltage) + AirLink IoT-based intelligent fault alert notifications for enhanced operational reliability.
