VORTEX COMPRESSOR – NEXUS Series DD PM VSD Compressor
DD PM VSD MODELS (7.5 – 55 kW | 7.5 – 10 BAR | 0.85 – 9.35 m³/min)
Enhanced efficiency and lower energy consumption are crucial in nearly all compressed air applications. In order to meet this demand, Vortex NEXUS PM-series are now equipped with permanent magnet motors. These systems consistently provide high-quality compressed air, even when the air demand fluctuates significantly.
Increased Free Air Delivery: Beyond reducing energy consumption, permanent magnet motors also increase free air delivery. Compared to asynchronous motors, this efficiency means more power is delivered to the motor shaft with consistent energy consumption. The compressor can then convert this power into increased air delivery while effectively managing extreme consumption fluctuations. This avoids unnecessary idle time and sudden load changes, reducing wear on components and cutting energy costs by eliminating inefficient idling.
