Envision a future where peak industrial efficiency isn't just an aspiration but a tangible reality. This future is being actively shaped by ELGi through its groundbreaking electric screw compressors. These compressors are more than just innovative machinery; they are the harbingers of a new industrial era. As we embark on this exploratory journey into ELGI's technological advancements, we'll uncover how these compressors are not merely revolutionizing existing standards but also creating new benchmarks in the industry.
Understanding Electric Screw Compressors
At the heart of modern industrial machinery lies the electric screw compressor, that powers the pneumatic tools.Electric screw compressors utilize a pair of interlocking helical screws, known as rotors, to compress air. This differs from piston compressors that use a reciprocating piston.
Process of Air Compression
- Air enters a sealed chamber, getting trapped between the rotating screws.
- As the screws rotate, the air moves along their threads, getting progressively compressed.
- The compressed air is then released at the desired pressure.
Advantages of Electric Screw Compressors
Let us explore the key benefits of electric screw compressors:
Energy Efficiency :
The crown jewel of electric screw compressors is their unparalleled energy efficiency. ELGi EG Series screw air compressor, with its eta-V profile rotors, operates at optimal speeds, dramatically reducing energy consumption. This efficiency translates into lower electricity bills and a reduced carbon footprint, making them a smart choice for eco-conscious businesses.
Enhanced Motor Power :
Electric screw compressors are equipped with the latest energy-efficient motors of class IE3, IE4, IE5. These motors ensure lower electrical power loss during the compression process.The motors also offer high grade of protection against environmental interference like dust and moisture, and can be defined by their IP rating. Special motors are used for variable frequency drive variants to offer the required turndown.
Cost-Effective for Larger Capacities :
When dealing with larger-capacity motors, the overall investment in power supply and distribution for high-voltage motors is generally lower than for low-voltage motors. This results in reduced line losses and saves on power consumption. Particularly, the use of 10KV high-voltage motors can directly leverage grid power supply, simplifying the use and reducing the failure rate while also decreasing the investment in power supply equipment.
Reduced Oil Contamination :
While compressed air in these systems is typically pure and free of oil, compressors may suffer from oil contamination due to incomplete scraping by the oil scraper ring or poor sealing. In electric screw compressors, such issues are significantly minimized, ensuring the compressed gas remains largely oil-free.
Lower Operational Costs :
One of the most compelling advantages of ELGI's electric screw compressors is their reduced operational costs. The 90-160 kW EG Series Screw Compressors are engineered for minimal maintenance needs. Their durable design and efficient operation mean fewer breakdowns and lower repair costs, ensuring a cost-effective long-term investment.
Environmental Friendliness :
ELGi’s compressors are designed with the environment in mind. The EG Series boasts the lowest oil carryover in the industry because of its innovative OSBIC process. This process ensures clean, oil-free air, minimizing environmental pollution. Additionally, the reduced noise levels make them ideal for operations where noise pollution is a concern.
Reliability and Durability :
Durability is a hallmark of ELGi’s electric screw compressors. The EG Series excels in harsh environmental conditions, ensuring reliable performance in temperatures ranging from the coldest to the hottest. This reliability is bolstered by the low operating speeds and low operating temperatures, extending the life of the compressors.
Enhanced Performance Features :
The EG Series is a symphony of advanced features. The variable speed drives (VFD) adapt compressor output to match demand, optimizing energy use and reducing wear. The advanced intake valve system and modulation unit ensure effective control of airflow, maximizing power savings. The air-oil separation system delivers consistently high-quality air, while the heavy-duty air filter system protects against contaminants.
