CORMAK LUFT 1000 VSD+PM COMPACT +500l tank

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

SET INCLUDES:

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

Key features that distinguish these models:

1. Permanent Magnet Motor (PM) Technology

Most compressors in the Energy Saver series utilize Permanent Magnet motors. Compared to standard induction motors:

- Achieve efficiency levels corresponding to IE4 or even IE5 standards.
- Maintain high performance even at very low RPMs (where standard motors lose efficiency outside their nominal range).

- These motors are more compact, lighter, and generate less heat.

2. Advanced Variable Speed Drive (VSD) Control

At the heart of the Energy Saver range is the frequency inverter (VSD).

- Needs-based adaptation: The compressor does not operate on a simple load/unload binary cycle. If your machine requires only 30% capacity, the compressor reduces its speed accordingly, consuming proportionally less energy.
- Elimination of idle running: Traditional compressors often continue running for several minutes after filling the tank, consuming about 25–30% of the rated power without producing air. Energy Saver models virtually eliminate this wasteful process.

3. Soft Start Function

Thanks to the VSD, these machines start smoothly from 0 Hz. This means no abrupt current surges during startup, which:

- Spares the facility’s electrical installation.
- Allows for frequent starting and stopping without risk of winding overheating.

4. Genuine Energy Savings

In practice, implementing the Energy Saver lineup can reduce electricity bills by 30% to 50% compared to traditional fixed-speed compressors. Additionally, the system maintains highly stable network pressure (accurate to 0.1 bar), which is crucial for precision equipment such as laser cutters. Extended service life: Absence of rapid pressure and temperature spikes prolongs the life of the screw element.
