Ingersoll Randn has expanded its contact-cooled rotary screw air compressor line with the R-Series 55-75kW/75-100hp range. The new range is available with either fixed speed or Nirvana variable speed drives at capacities up to 3.23-13.56m3/min.

Ingersoll Rand compressor products are exclusively distributed in Australia by Compressed Air and Power Solutions Australia (CAPS) — the largest independently-owned compressed air company in the country.

According to CAPS national sales manager Dino Alessio, “The 55-75kW range of R-Series compressors has new features and options that will deliver increased reliability, efficiency and productivity for customers, while providing the same industry-leading benefits offered by the larger R-Series compressors.”

The new machines are equipped with the Xe-Series controller, which features a high resolution LCD colour display. The monitor provides immediate and intuitive access to all vital compressor data and settings. The controller also permits remote control of the compressor from any PC, tablet or smartphone via the internet and can send automatic email notifications of trips and warnings to designated personnel.

The integrated Total Air System (TAS) dryer and filtration option provides clean, dry air in a single package, reducing installation costs while allowing single-point maintenance and monitoring for the whole 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 utilises 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 55-75kW R-Series range retains the same advanced features introduced with the larger 90-160kW/125-200hp range. 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 leaks. Sequential cooling utilises a centrifugal blower, which uses much quieter cooling fans to consume less energy.

R-Series compressors are designed for reduced maintenance and easy serviceability. By utilising 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.
