Best-in-class maintenance and operating cost
Due to our efficient air filtration system in EN Series Compressor, cleaner suction air keeps the internal components of the compressor clean, which helps in maintaining optimum cooling efficiency and low oil-fill, hence increasing the life of consumables.

Efficient air-oil separation
The air-oil separation of our EN Series electric screw air compressor is derived by impact and deceleration, which involves 3 stages. Stage 1: Impact of air-oil mixture on the tank circumferential area. Stage 2: Deceleration action of air-oil mixture to remove the oil particles. Stage 3: Air with minor traces of oil enters the spin-on separator for purification.

Optional variable speed drives for energy efficiency
ELGi EN Series Compressor matches output with demand by varying motor speed as per the demand. The power consumption also reduces with time, which helps eliminate frequent load-unload cycle, thereby providing energy savings.

Indigenously designed Neuron controllers for ease of operation
The Neuron XT controller has been custom designed and engineered as an efficient control solution for our EN Series, which allows you to monitor and control overall performance with easy-to-use service indications, malfunction alarms & safety shutdowns.

Highly efficient belt drive transmission
ELGi electric screw compressor ensures efficient power transmission with minimal losses.

HOW DO EN SERIES SCREW COMPRESSORS WORK?

The rotary screw air compressors of the ELGi EN series operate systematically to produce compressed air for a wide range of industrial applications.

An intake filter ensures that contaminants are eliminated before the air enters the system, starting with 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 compression chamber, where male and female rotors of interlocking helical screws rotate anticlockwise, is where the compressor's heart is located. 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 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 are used to distribute the compressed air for numerous industrial applications.
