Variable speed screw compressor

High-efficiency screw compressors – design lies in the details

With increased efficiency and stable compressed air production in the PM compressor series, we ensure the supply of compressed air, which is the beating heart of your production process.

As an ideal teammate, these compressors are easily coordinated with existing control systems via the quality control panels used to provide exactly the amount of compressed air you need.

Your benefits with the new generation of screw compressors

Energy savings:
The screw compressors are equipped with frequency drives with IE5 class motors, in accordance with the IES2 system efficiency standard

These features result in a significant reduction in power consumption and energy costs.

Advantages of screw compressor with permanent magnet motor (PM) with variable speed drive (PM VSD)

Integrated air handling unit and electric motor:
- The permanent magnet (PM) motor is synchronous and does not lose its magnetic properties using neodymium boron magnets up to 120 degrees Celsius.
- The stator winding with a special corona-resistant coating ensures high durability.
- The efficiency of this motor is 9% higher than that of asynchronous motors and is designed for 10 years of reliable operation. The direct connection of the impeller and the permanent magnet motor (without coupling or bearings) allows for 100% power transmission and up to 6% more efficiency is achieved by using an inverter.

- The air handling unit production line is equipped with precision German and Japanese machines for rotor grinding, and the optimized rotor profile results in higher flow rates and lower operating costs.
Variable Speed Drive (VSD):
- Motor speed control and reduced starting current result in smooth and quiet operation.
- Energy savings of up to 35% with variable drive and up to 42% in combination with PM motor.
Intelligent Controller (PLC):
- Prevents sudden stops by monitoring key parameters.
- Touch screen allows viewing, controlling and adjusting parameters Makes.

More Benefits of Permanent Magnet Screw Compressor with Variable Speed Drive (PM VSD)

Advanced Cooling System
– Larger heat exchanger is designed to dissipate heat effectively, which increases the overall durability of the system and more stable performance under long-term operating conditions.
Smart Compressor
– Precise scheduling to turn on and off at specific times
– Ability to adjust pressure based on the specific needs of each process, thereby increasing efficiency and reducing energy consumption
Long-life consumables Top
– The oil separation system reduces the amount of oil remaining in the compressed air to less than 3 ppm, which protects the equipment and minimizes maintenance costs.
Precise pressure control
– The ability to adjust the pressure within a certain range based on the actual consumption needs
– The compressor produces air exactly according to the consumption, and energy waste is avoided
