Ingersoll Rand releases the latest model in the contact-cooled Rotary Screw Air Compressor line — the R-Series 37-45 kW (50-60 hp).  “The R-Series product line offers reliable, productive and efficient air compressors in the ranges our customers need,” said Scott Hardeman, marketing manager – Customer Center and Association of Ingersoll Rand Distributors (AIRD) channels, Ingersoll Rand. “We also offer add-on features so each customer can customize the product for their unique application requirements.”  The 37-45 kW compressor is equipped with the same V-Shield™ technology as the larger 55-160 kW units. 

The V-Shield ensures that the compressor’s piping system is composed of stainless steel pipes, metal-flex hoses and elastomeric face seals to prevent leaks. The piping system is also configured to minimize the adverse affects of vibration, including loosening of connections, unwanted flexing in joints, air leaks and extreme noises.  Along with the V-Shield technology, the 37-45 kW compressor comes in fixed-speed or Nirvana Variable-Speed Drive (VSD) options. Fixed-speed units are best suited for constant-demand systems; VSD units increase the efficiency of variable-demand applications. The VSD compressor is also equipped with a Hybrid Permanent Magnet motor — the highest-efficiency motor available from Ingersoll Rand — to increase energy savings.  

The R-Series compressor is manufactured with a sequential cooling system for added operating efficiency. Independently mounted coolers reduce thermal stress, decrease discharge temperatures and lower the energy required to remove condensation in downstream air treatment. As a result, the compressor produces dryer air more cost effectively.  Coupled with the sequential cooling system, the compressor’s Progressive Adaptive Control (PAC) continuously monitors filtration and temperatures. This control technology defines operating parameters and eliminates moisture build-up that can damage internal components of the compressor and result in unexpected downtime.
