R-Series Line of Rotary Screw Air Compressors


Ingersoll Rand  has expanded its contact-cooled rotary screw air compressor line with the R-Series 55-75 kW / 75-100 hp range.  The new range is available in fixed speed and Nirvana variable speed drive at capacities up to 3.23-13.56 m3/min / 114-479 cfm.

“With the 55-75 kW range of R-Series compressors, we are able to introduce new features and options that deliver reliability, efficiency and productivity for our customers, while providing the same industry-leading benefits offered by the larger 90-160 kW R-Series compressor range,” said Robert Horneman, global portfolio manager for Ingersoll Rand.
The new range of compressors is equipped with the Xe-Series controller, which features a high resolution LCD color display that provides immediate and intuitive access to all vital compressor data and settings. Further, the controller allows access and remote control of the compressor from any PC, tablet or smartphone via the internet and can send automatic email notifications of trips and warnings.
The integrated Total Air System (TAS) dryer and filtration option provides clean, dry air in a single package, minimizing installation costs and footprint while allowing single-point maintenance and monitoring for the complete system. The Total Air System option comes with refrigerated dryer technology and a high efficiency coalescing filter to deliver ISO Class 1-4-2 quality air. The TAS option utilizes a patented 3-in-1 heat exchanger, which improves energy efficiency and lowers operating cost when compared to traditional stand-alone dryers.

In addition to the new Xe-Series controller and TAS option, the 55-75 kW R-Series range boasts the same advanced features introduced with the larger 90-160 kW / 125-200 hp range: PACTM protection, V-Shield™ technology, and sequential cooling. Progressive Adaptive Control™ (PAC) protection is an integrated, intelligent system that monitors filtration, ambient temperature and other parameters and adapts the operation of the compressor in order to reduce energy consumption, lower noise and increase uptime. V-Shield technology is a superior configuration using stainless steel pipes, durable metal-flex hoses and a vibration isolation system to eliminate possible leak paths. Sequential cooling utilizes a centrifugal blower, which consumes less energy and operates much quieter than traditional cooling fans.
R-Series compressors are designed for reduced maintenance and easy serviceability.  By utilizing swing out separator covers, longer life consumables, easy-access hinged doors, single side maintenance access and slide out coolers, the time needed to service and maintain the compressors has been significantly reduced.
