ELGi introduces AB Series oil free screw air compressors for pharma industry

By OEM Update Editorial August 8, 2020 1:19 pm IST

Pharmaceutical customers traditionally buy oil lubricated compressors for requirements below 500cfm (90kW) owing to low capital investments, and conventional oil free compressors, to meet stringent air quality requirements. The flip side of using lubricated screws is the multi-layer filtration systems which increase pressure drop and cause down time due to the replacement of oil filters resulting in increased lifecycle costs. On the other hand, conventional oil free compressors in this range, are normally air-cooled and also face reliability issues and temperature trips at high ambient temperature conditions (above 45-degree C), resulting in significant downtime and operational losses, in addition to excessive initial and running costs.

To deal with this, compressor manufacturer ELGi has introduced AB Series range of oil free screw compressors, to deliver pure, clean, class “0” oil free air. “With high reliability, consistent air quality, better return on investment, lower cost of ownership, and fast, efficient service support for sensitive applications with moisture content between (+) 3-degree C, to (-) 20-degree C PDP; the AB series range of air compressors meets the ISO 8573–1 compliance requirements,” ELGI claims.

The ELGi AB Series has a unique air cooling system which ensures ample condensation of water from air particles, aiding the self-replenishment of water in the closed loop. This eliminates the need for external water top-up and also reduces the load on the driers and the water management system. The in-built microbial inhibition system prevents microbial growth, across all scenarios of operation, thereby ensuring microbe free air.
