Why Use a Screw Compressor?

Screw Compressors Provide Continuous Air Flow and Pressurization

Screw compressors from AERZEN are designed to provide optimal air flow and pressurization at all times. Continuous air flow eliminates the need to stop operations in order to fill or change out air receiver tanks. Through deliberate design and engineering, intake and outlet openings in our screw compressors have been improved and pressure losses reduced, resulting in reliable achievement of the desired discharge pressure.

Screw Compressors Are Versatile and Flexible

The versatility of screw compressors makes them suitable for use in many applications that need reliably compressed air, nitrogen, and other neutral and special gases.

Oil-free screw compressors are especially suitable for applications where hygiene is vital such as medical and lab processes, food technology, transporting powder pneumatically, or bulk goods transportation in which the presence of oil or moisture could cause contamination. Power plants and the chemical industry also rely on oil-free screw compressors for the supply of pure air.

Generally, screw compressors provide a significant increase in performance and energy efficiency due to the reduced contact of moving parts, despite the better heat dissipation and sealing.For almost any process that demands high efficiency and durability, screw compressors perform well.

A Screw Compressor Provides Higher Performance and Energy Efficiency

A twin-screw compressor is a rotary compressor that compresses gas through the rotation of the twin-screw meshing rotors. The compression space gradually reduces, compressing the volume of gas.

This results in the production of reliable compressed air necessary for many industrial and other technological applications. In addition, with a twin-screw compressor, you experience:

  • Higher energy efficiency (lower energy consumption and heat production)
  • Higher reliability
  • Less wear and tear
  • Lower maintenance needs

Fewer Pulsations Means Less Noise

Twin-screw compressors are incredibly quiet when in use. They operate with reduced vibrations because they are enclosed in sound-inhibiting systems and have less contact between their moving parts. This creates fewer pulsations, which means less contact, less friction, and, hence, less noise.

In fact, in AERZEN’s dry-running screw compressors, the rotors never touch. Although some units produce approximately 60,000 pulsations per minute, our screw compressors are engineered to be as quiet as possible. 

Vibration Control and Monitoring

Unlike reciprocating compressors, some twin-screw compressor systems use a constant speed  frequency-controlled motor that reduces contact between moving parts. This system creates pressure pulsations that cause compressor vibration at the pulsating frequency but not as high as with reciprocating compressors. The reduced vibration results in quieter operation while a well-insulated sound hood helps to further reduce noise and vibrations.

However, the trend is towards frequency-controlled motors. Today we see about 60% of the compressors with a fixed speed and 40% with a frequency converter (= variable speed). Screw compressors can also have machine noises of >80 db(A) - here it is important to have good insulation in the form of a well-insulated sound hood.

Less Maintenance

Screw compressors are low-maintenance and energy-efficient because they have 70% fewer moving parts, which means less contact between parts, fewer oscillating forces, and less wear and tear. Screw compressors also have higher compression efficiencies because they don’t lose as much suctioned air.

A twin-screw compressor also enables a significant reduction in CO2 emissions and energy consumption due to the highly efficient screw compression process.

Perfect Noise Reduction

Twin-rotor rotary screw compressors have lower noise levels than reciprocating compressors due to their unique mechanics. These machines draw in a continuous flow of air, eliminating excessive pulsation. Twin-screw compressor technology is so quiet it can generate only 69 dB when in use, which is equivalent to the sound of an operating dishwasher.

Higher Compressor Power

Rotary screw compressors are designed to achieve higher airflow rates. This means they can run heavy-duty equipment or tools with high power at maximum efficiency while ensuring energy savings. They can do this because they compress air continuously with reduced pulsation, resulting in high efficiency at 80% load and low efficiency when partly loaded.

Safer Compressor Operation at Higher Temperatures

Most rotary screw air and oil-lubricated compressors can pressurize air in both low and high temperatures. This means they can run to 100 - 110 degrees Fahrenheit above room temperature without affecting performance.

In other circumstances, if a compressor room surpasses 100 degrees Fahrenheit, there are inherent dangers associated with the process. Namely overheating can lead to equipment damage that requires operational downtime to perform maintenance. However, these dangers are non-existent with a rotary screw compressor due to the built-in heat recovery mechanisms. Delta Screw Compressors from AERZEN, for example, can safely work at a room temperature in excess of 122 degrees Fahrenheit.

Easy Operation and Flexible Retrofitting Possibilities

Rotary screw compressors also have smooth belt drives in the 5+ generation, making it possible to install various belt pulleys that achieve a perfect operating ratio. This makes the screw compressor flexible should you need to make any changes in the future, eliminating the need to replace your compressor with a different model or a different gear box / transmission.

Belt drive maintenance is also low because the weight of the motor guarantees the correct tension every time. Due to the weight of the motor we have a self-tensioning system. Many of these machines also utilize electronic controls for higher precision and exact adherence to desired pressure ranges.

Furthermore, the housing on a rotary screw compressor has an integrated control panel, which allows you to arrange the units in space-saving configurations and perform regular maintenance for optimal operation.
