Kondisi: baru, Tahun pembuatan: 2026, CORMAK LUFT 1500 VSD+PM Compact Screw Compressor with dryer – a compact set for demanding applications - ENERGY SAVER THE SET INCLUDES: LUFT 1500 VSD+PM COMPACT SCREW COMPRESSOR with integrated dryer. HORIZONTAL COMPRESSED AIR RECEIVER, 500 L. Key features distinguishing these models: 1. Permanent Magnet Motor Technology (PM) Most compressors in the Energy Saver series are equipped with Permanent Magnet motors. Compared to conventional induction motors: They offer efficiency compliant with IE4 or even IE5 standards. Maintain high efficiency even at very low speeds (standard motors lose efficiency outside their nominal range). Are more compact, lighter, and generate less heat. 2. Advanced Inverter Control (VSD) The heart of the Energy Saver line is the frequency inverter (variable speed drive). Demand-driven operation: The compressor does not operate in a simple "all-or-nothing" (load/unload) mode. If your machine requires only 30% output, the compressor reduces its speed, consuming proportionally less energy. Elimination of idling: Conventional compressors often continue running for several minutes after the tank is filled, drawing about 25–30% of nominal power while not producing air. Energy Saver models virtually eliminate this wasteful process. 3. Soft Start Thanks to the inverter, these units start smoothly from 0 Hz. This results in no sudden current surges at startup, which: Protects the electrical installation in your facility. Allows for more frequent starts and stops without the risk of winding overheating. 4. Genuine Energy Savings In practice, implementing the Energy Saver line enables a reduction of electricity costs by 30% to 50% compared to traditional fixed-speed compressors. Moreover, the system maintains extremely stable network pressure (accurate to 0.1 bar), which is crucial for precision equipment such as laser cutters. Extended lifetime: The absence of rapid pressure and temperature fluctuations extends the screw element’s operating life.

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.
