CORMAK LUFT 1000 VSD+PM Compact Screw Compressor with Dryer – Compact Set for Demanding Applications – ENERGY SAVER

SET INCLUDES:

• LUFT 1000 VSD+PM COMPACT screw compressor with integrated dryer.
• 500L horizontal compressed air receiver.

Key features distinguishing these models:
1. Permanent Magnet Motor Technology (PM)

Most compressors in the Energy Saver series use Permanent Magnet (PM) motors. Unlike standard induction motors:
• They offer efficiency levels at IE4 or even IE5 class.
• They maintain high performance even at very low speeds (standard motors lose efficiency outside their nominal range).
• They are smaller, lighter, and produce less heat.

2. Advanced Variable Speed Drive Control (VSD)

The heart of the Energy Saver line is the frequency inverter (VSD).
• Demand-based operation: The compressor does not operate in a simple “all or nothing” (load/unload) mode. If your machine only needs 30% output, the compressor reduces speed, consuming proportionally less energy.
• Elimination of idle running: Conventional compressors often keep running for several minutes after the tank is filled, using around 25-30% of nominal power without producing air. Energy Saver models virtually eliminate these wasteful losses.

3. Smooth Start (Soft Start)

Thanks to the inverter, these units start smoothly from 0 Hz. This means no sudden current spikes at startup, which:
• Reduces stress on the facility’s electrical system.
• Allows more frequent start/stop cycles without risk of winding overheating.

4. Genuine Energy Savings

In practice, using the Energy Saver line can reduce electricity costs by 30% to 50% compared to conventional fixed-speed compressors. The system also maintains highly stable network pressure (accurate to 0.1 bar), which is critical for precision equipment such as laser cutters. Longer lifespan: The absence of sudden pressure and temperature spikes extends the screw stage’s operational life.
