Electric Powered Screw Compressors : Global Series E11 - E22

Global Series (E11-E22 kW) Electric Powered Screw Air Compressors (EPSAC) Global Series (E11-E22 kW)

 
Features: 

Save Energy 
"Flexair " BLEED: Direct Drive Airends

The Global series compressors gain their efficiency by using Elgi's patented "BLEED" airends with unique "N" profile rotors

Elgi's Flexair Advantage 
* Improved overall energy efficiency of the compressor due to very low operating speed 
* Low maintenance costs due to absence of gear/pulleys etc 
* Low operating noise levels 
* Less number of components resulting in compact design of the compressor

Axis Airends 
* Belongs to the family of Elgi's highly-efficient N-profile Axis airends ranging from Axis 35 - Axis 310 
* Very high volumetric efficiency 
* Unique Axis profile rotors for flow starting from 35 lpm 
* Proven design with thousands of installations worldwide 
* Certified to conform to CE standards 

Intake Valve System : Reduced Starting Load 
The new generation capacity control system integrated with blow down valve is installed at the compressor inlet. Intake valve optimally controls the compressor capacity during start up reducing the no-load power. This Optimal Capacity Control results in direct savings on power consumption 

Efficient air-oil separation with OSBIC ( 3 stages) 

Elgi has applied unique OSBIC process (Oil Separation by Impact and Centrifugal Action) which enables efficient separation of air and oil, with minimum pressure drop. The method enables separation of oil in three stages, delivering consistent oil-free air while increasing the life of separator element

99% bulk water free 
Depending on the humidity level of inlet air, bulk water remains in compressed air at varying levels and causes corrosion of piping, end tools, machinery and valves. Global Series air compressor has a custom-designed centrifugal type moisture separator with an automatic timer controlled drain. This comes as apart of the package at no extra cost and removes over 99% of bulk water from the compressed air, resulting in corrosion free, longer life of end use equipments and less load on the dryer 

Efficient air cooling 
The cooling system with fans and larger cooling surface area enhances the cooling of hot air. The fan motor uses significantly low power. The integrated fan-motor assembly maintains low temperature there by increasing the life of motor. Designed to meet CE norms, the cooling system enables ease of maintenance and ducting. More over, the complete system is insulated immediately internally from other zones 

Reliability under extreme conditions 
Global series compressors are designed to perform at extreme temperatures- from hot summer to cold winter, and from dry to extremely humid conditions

Microcontroller edge 
* Built-in dryer dew point integration
 
* VFD parameter (Power, HMR, Frequency, Ampere, Voltage) 
* Read out and closed loop control 
* Selectable AO (Pressure/temperature/ Dew point) for DCS integration 
* Controlled Auto Drain System

Reports 
Cumulation Report ( Run Hours, Load hours, unload hours, Stop Hours, Fault hours, Number of stops and remaining AFCT, OFCT, OSCT, OCT, and RGT) 
* Detail Report- previous 15 days ( load hours, Unload hours, Stop hours, Fault hours, and Number of times machines stopped due to stand-by) 
* Fault Report- ( Previous 99 faults in chronological order with Real time Stamping and type of fault)
