ELGi EN Series Lubricated Screw Air Compressor 4-50 HP

WHY ELGi EN SCREW AIR COMPRESSOR SERIES?

Best-in-Class Reliability
ELGi’s EN Series screw air compressors are designed to encapsulate all functional components and the compressor within one common housing. With their small footprint, high reliability, and low maintenance requirements, the EN Series compressors are ideal for small and medium scale industries such as food packaging, sorting, garages, machining, and fabrication workshops.

Compact & Elegant Design
The EN Series is compact and offers a space-saving design powered by ELGi’s energy-efficient η-V profile, with low possibility of leaks due to integrated components and connections.

Energy-efficient
ELGi’s EN Series screw air compressors come with our unique, compact, and silent assembly that offers energy-efficient operations with minimal pressure drops across the system.

Best-in-class Maintenance & Operation Cost
The EN Series has a slow-running airend with fewer parts and connections than any other compressor in its class, which ensures minimal maintenance.

Efficient Air-Oil Separation
The air-oil separation in the EN Series isachieved through the impact and deceleration. In the circumferential tank area, the impact of the air-oil mixture prompts deceleration action to remove the oil particles from the air. The air with minor traces of oil then enters the separator for further purification.

Optional Variable Speed Drive for Energy Efficiency
ELGi offers a variable speed drive option for the EN Series EN07-EN15 models.Variable Speed Drives help air compressors match the compressed air output with demand by varying the motor’s speed. When the demand goes down, the power consumption also goes down, eliminating the frequent load unload cycle, thereby saving energy over time.

Indigenously Designed Neuron Control System Offering Operational Data & Safety Measures
The EN Series screw air compressors are equipped with a custom designed and engineered Neuron XT controller. They come with several features, like malfunction alarms, safety shutdowns, and easy-to-use service indications allowing you to monitor and control the machine's overall performance.

Low Noise Levels
ELGi’s EN Series screw compressors are known for their low noise levels. At 65 dBA the EN Series offers the lowest sound level in the industry. Making them perfect in conditions where noise levels can affect the working conditions of your staff.

They are energy efficient and are low maintenance. Their flexible sizes allow for a balanced air supply for diverse applications, enhancing the process.

FREQUENTLY ASKED QUESTIONS

What maintenance is required for an oil-lubricated rotary screw air compressor?

Regular maintenance includes changing the compressor oil, replacing oil filters, checking and tightening belts, inspecting air and oil coolers, and cleaning or replacing air filters. Maintenance schedules can vary based on usage and manufacturer recommendations.

What are the advantages of using an oil-lubricated rotary screw compressor?

Oil-lubricated rotary screw compressors offer superior cooling and sealing, ensuring efficient operation and longer lifespan. They also provide consistent air quality because of efficient filtration and moisture separation. Furthermore, these compressors are excellent for high-demand industrial applications, delivering consistent and reliable compressed air delivery.

How do EN Series screw compressors work?

The rotary screw air compressors of the ELGi EN series work systematically to produce compressed air for a range of industrial applications. An intake filter ensure that contaminants are eliminated before the air enters the system, starting with the intake of atmospheric air. The air is cleared of dust and other contaminants after going through a filtering stage, which is essential for avoiding internal component damage. The compressor's heart is located in the compression chamber, where male and female rotors of interlocking helical screws rotate anticlockwise. The air is drawn into the profiles of these screws as they rotate, gradually compressing the gas inside. Some designs allow oil injection into the compression chamber, which helps seal screw gaps, promotes compression, and dissipates heat. After compression, the compressed air is cooled to retain efficiency, and any remaining oil is removed using an oil separation mechanism. The pressure of the compressed air is carefully controlled by sensors and control systems, and it is kept in a receiver tank to buffer variations in demand. In the end, pipelines distribute the compressed air for numerous industrial applications. For precise information on the capabilities of the ELGi EN Series screw-type air compressor, it is advised to check official sources or their technical support.
