 55 kW – The latest-generation SED+ series permanent-magnet two-stage variable-frequency screw air compressor

The SED+ series 55 kW gear-driven two-stage variable-frequency screw air compressor features dual frequency converters for noise reduction and a modular split design, delivering 35% higher overall energy efficiency than standard models. Equipped with AirLink IoT management, it ensures stable air supply for continuous production lines.

1. The dual-inverter noise-reduction design employs frequency-conversion vector control for both the main motor and fan motor, effectively extending the fan's service life and reducing noise levels.

2. The innovative modular split design simplifies and accelerates daily inspection and maintenance tasks, ensuring production continuity.

3. Equipped with a two-stage permanent magnet variable-frequency screw motor paired with an IE5 motor, the system achieves a comprehensive energy efficiency ratio 35% higher than that of standard-frequency models, far exceeding the first-tier energy efficiency standard.

4. Robust protection with IP55 rating, featuring a bionic fan that operates silently at 78 dB and delivers stable full-load performance even under high temperatures of 45°C.

5. Equipped with the AirLink IoT smart IoT platform, customer information creation, device outbound allocation, and inventory management are all handled in one place.
