Textiles

EG series oil-flooded screw compressors are crucial for various critical operations in the textile industry. They are commonly used to power air-jet weaving machines, which require a constant supply of compressed air to drive the yarn through the loom at high speeds. Compressed air is also used in numerous textile activities for cleaning, dust removal, and fibre tension control. The EG series compressors are reliable and efficient machines that ensure uninterrupted production and minimise downtime in textile manufacturing.

Cement

The cement industry relies on electric screw compressors to produce compressed air for various applications. One of the most popular applications is in pneumatic conveying systems, which transport raw materials like limestone and clay to various stages of the production process. These compressors also provide power to the air-operated tools used in cement plants for equipment maintenance and repair. ELGi screw compressors also help to regulate the combustion process in cement kilns by providing air for effective fuel combustion, resulting in energy savings and lower emissions.

Paper & Pulp

The EG series is employed in the paper and pulp industries for various critical operations. They provide compressed air to the pneumatic actuators and controls of paper machines, ensuring precise and efficient paper production operations. Compressed air is also used for chemical mixing, valve control, and material transportation in the paper pulp manufacturing process. The reliability and consistent performance of the compressor are crucial for maintaining the paper and pulp industry's quality and production efficiency.

Machine Tool Shops

Oil-lubricated rotary screw compressors are used for various vital functions in machine tool shops. The compressed air is used for several applications like the actuation of pneumatic cylinders in CNC machines, cleaning, air guns and many more. All these applications require air to be clean to prevent corrosion of machine components.

Steel Making

EG series screw air compressors are essential in various applications in the steel industry. They are used in steel mills to power pneumatic equipment and controls and to create oxygen, which is essential in the steelmaking process. Compressed air is used to clean equipment, manipulate valves, and operate machines, among other things. A reliable and efficient air compressor is crucial to meet the high production needs and safety regulations associated with steel manufacturing.

Food Processing

Screw air compressors for the food industry are essential in delivering compressed air for various applications. They power pneumatic machines used in packing, labelling, and filling. Furthermore, compressed air is used in food preservation processes, including freeze-drying and nitrogen generation, to ensure product quality and safety. These compressors are appropriate for applications where contamination control is vital, meeting the high norms and regulations of the food processing industry.

HOW DO EN SERIES SCREW COMPRESSORS WORK?

The ELGi EN series rotary screw air compressors work systematically to produce compressed air for a range of industrial applications. An intake filter ensures that contaminants are eliminated before the air enters the system, starting with the ambient air intake. 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, promote compression, and dissipate heat. After compression, the compressed air is cooled to retain efficiency, and any remaining residue of 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, the pipelines distribute the compressed air for numerous industrial applications.
