CORMAK LUFT 1500 VSD+PM Compact Rotary Screw Compressor with Dryer – Compact Set for Demanding Applications – ENERGY SAVER

SET INCLUDES:

LUFT 1500 VSD+PM COMPACT rotary screw compressor with integrated dryer.
500 L horizontal compressed air receiver.

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

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

They offer efficiency levels meeting IE4 or even IE5 standards.
Maintain high performance even at very low speeds (where standard motors lose efficiency outside their nominal range).
Are smaller, lighter, and generate less heat.

2. Advanced Inverter (VSD) Control

At the core of the Energy Saver line is a frequency converter (inverter).

Demand-driven operation: The compressor does not operate in an all-or-nothing (load/unload) mode. When your equipment requires only 30% capacity, the compressor reduces RPM accordingly, consuming proportionally less energy.

Elimination of idle running: Traditional compressors often run for several minutes after the tank is filled, consuming approx. 25–30% of nominal power without producing air. Energy Saver models almost completely eliminate this wasteful process.

3. Soft Start

Thanks to the inverter, these units start smoothly from 0 Hz. This means there are no sudden current surges during startup, which:

Protects the facility’s electrical installation.
Allows more frequent start/stop cycles without risk of motor winding overheating.

4. Tangible Cost Savings

In practice, using the Energy Saver line enables reducing electricity bills by 30% to 50% compared to traditional fixed-speed compressors. The system also maintains highly stable network pressure (accurate to 0.1 bar), which is crucial for precision machinery such as laser cutters. Extended service life: The elimination of sudden pressure and temperature spikes increases the lifetime of the screw assembly.
