Energy Saver Range: A New Era of Efficiency
The Energy Saver range is an advanced series of screw compressors designed to drastically reduce operating costs. In a world where energy accounts for nearly 80% of the cost of maintaining a compressed air system, these models are becoming a standard in modern industry.
The key features that distinguish these models are:
1. Permanent Magnet Motor Technology (PM)
Most compressors in the Energy Saver range use Permanent Magnet motors. Unlike standard induction motors, they:
-
Achieve efficiency levels meeting IE4 or even IE5 standards.
-
Maintain high efficiency even at very low speeds, whereas standard motors lose efficiency outside their nominal operating range.
-
Are smaller, lighter and generate less heat.
2. Advanced Variable Speed Drive Control (VSD)
The core of the Energy Saver range is the frequency converter, also known as a variable speed drive.
-
Demand-based adjustment: The compressor does not operate in an “all or nothing” load/unload mode. When your machine requires only 30% of the available output, the compressor reduces its speed and uses proportionally less energy.
-
Elimination of idling: After filling the receiver, conventional compressors often continue operating for several minutes, consuming approximately 25–30% of their rated power without producing air. Energy Saver models almost completely eliminate this wasteful process.
3. Soft Start
Thanks to the variable speed drive, these machines start smoothly from 0Hz. This prevents sudden current surges during start-up, which:
4. Genuine Savings
In practice, using the Energy Saver range can reduce electricity costs by 30% to 50% compared with conventional fixed-speed compressors. The system also maintains highly stable network pressure, with an accuracy of 0.1bar, which is essential for precision equipment such as laser cutting machines. Longer service life: The absence of sudden pressure and temperature fluctuations extends the operating life of the screw unit.
Main Advantages of Permanent Magnet PM Motors
Permanent Magnet Motors, also known as PM motors, represent an innovative approach to electric drives and offer several significant advantages over conventional induction motors.
- Higher energy efficiency: This is one of their key advantages. PM motors do not require current to be supplied to the rotor to generate a magnetic field because the field is produced by the permanent magnets themselves. This eliminates energy losses in the rotor, including reactive power and Joule losses, resulting in significantly higher efficiency, often exceeding the requirements of the IE4 Super Premium class. High efficiency is also maintained across a wide range of loads and speeds, particularly at lower rotational speeds.
- Higher power factor: PM motors have a higher power factor, which means that they draw less current from the mains for the same useful output. This benefits the entire electrical installation by reducing network load and lowering costs associated with reactive power.
- Compact design and higher power: Thanks to the strong, constant magnetic field generated by the magnets, these motors can deliver higher power from a smaller housing. They are lighter and more compact than induction motors of comparable power, which is important in applications where space and weight matter, such as electric vehicles and robotics.
- Constant torque and high dynamic response: PM motors can generate constant torque even at low speeds and provide a fast dynamic response. Low rotor inertia enables rapid speed changes and precise control, making them ideal for applications requiring accurate positioning, such as CNC machine tools and industrial robots.
- Wide speed adjustment range: By applying magnetic field weakening strategies, these motors can operate across a very wide speed range while maintaining high efficiency.
- Improved reliability and durability: Reduced heat generation, a simpler rotor design without windings and lower mechanical loads contribute to longer and more reliable operation.
VSD Inverter – The Key to Optimising Compressor Operation
An inverter, also known as a variable speed drive, is an advanced electronic device that transforms the way screw compressors operate. It enables smooth adjustment of the compressor motor speed according to the current demand for compressed air.
Key advantages of compressors equipped with an inverter:
- Significant electricity savings: This is the principal advantage of an inverter. Conventional compressors operate at full output or are switched off, and excess air is often discharged. An inverter allows air production to be matched precisely to consumption. The compressor operates only at the power currently required, eliminating idling and losses caused by start/stop cycles. Depending on the air consumption profile, this can result in energy savings of 20–50%.
- Stable system pressure: By continuously adjusting the motor speed, an inverter compressor maintains almost perfectly constant pressure in the compressed air network, regardless of fluctuations in demand. This is essential for the correct operation of pneumatic tools and machines, prevents pressure surges and improves the precision of technological processes.
- Reduced starting currents and network loads: The inverter provides a soft motor start, eliminating the high inrush currents associated with conventional star-delta starting. This protects the electrical network against overload and extends the service life of the motor and other components.
- Extended component service life: Fewer abrupt starts and stops, together with operation under optimum load conditions, significantly reduce mechanical wear on the screw block, bearings and motor. This results in a longer overall compressor service life and lower servicing costs.
- Quieter operation: When air demand is lower, the inverter reduces the motor speed, directly lowering the compressor’s noise level. This improves working comfort in a production hall or workshop.
- Greater flexibility and adaptation to demand: An inverter compressor is particularly suitable for applications with variable compressed air demand, which is typical of most production facilities. It can operate efficiently under both low and high loads.
- Advanced control and diagnostics: Modern inverters are integrated with control panels and provide extensive functions for monitoring operating parameters, fault diagnostics, remote control and maintenance planning, giving full control over the compressed air system.
An investment in an inverter compressor quickly pays for itself through substantial energy savings and improved operating reliability. It is an ideal solution for businesses that value efficiency, durability and optimised operating costs.

2. Refrigeration System Evaporator
In the second stage, the compressed air enters the evaporator, where it is cooled to a dew point temperature of 3°C. This causes the water vapour and oil particles contained in the air to condense.
3. Condensate Separator
After cooling, the gas and condensate mixture enters an efficient separator, where the condensate is separated and discharged automatically from the unit.
