Ingersoll Rand, a specialist in compressed air systems, has introduced two new series in its range of R-Series compressors, bringing modernisation and enhanced value to the company’s compressed air solutions. These are the fixed and variable speed drives R-Series 5-11 kW rotary screw compressor and R-Series 30-37 kW contact-cooled rotary screw air compressor
The vertically stacked compact design of the R-Series translates to a 20% carbon footprint reduction; and with reduced sound levels – as little as 69 decibels, the series is ideal for use in the commercial sector where space is restricted or ambient sound levels are important. Both series are available with a total air system (TAS) option, which comprises a complete compressor, cooler and dryer system with integrated controls, water separators, drain ports, filter and receiver tanks.
The 5-11 kW rotary screw compressor
This affordable compressor has extended the R-Series family into the commercial machine range. With a compact design and new features, it fits virtually any application environment.
Among the innovations that reinforce Ingersoll Rand’s reputation for reliability are the leak-free, next generation air-end, improved seals and reduced number of components. The range comprises three models with two variations each. These are the R5.5i and R5.5i TAS; R7.5i and R7.5i TAS; and R11i and R11i TAS. The TAS variation delivers ISO Class 1-5-1 quality air, measured in accordance with ISO 8573-1:2001. A convenient programmable control system is standard. This uses Ingersoll Rand Xe Series controllers, which deliver increased control functionality through an intuitive user interface and has large navigation buttons for both fixed and variable speed drives.
A common platform accommodates the fixed and variable speed drives in the same unit, while the plug-in Danfoss drive eliminates overheating and related component failures. An improved cooler design minimises thermal expansion effects and, as far as energy efficiency is concerned, the IE3 energy efficient fixed and variable speed motors support continuous operation up to 46°C.
The 30-37 kW contact-cooled rotary screw compressor
Comprising two models and two variations of each model – R30i and R30i TAS; and R37i and R37I TAS – this range of rotary screw compressors integrates advanced features from Ingersoll Rand. These include Ingersoll Rand’s V-Shield technology, an independent cooling system and the new Xe-Series controller.
V-Shield technology is used to virtually eliminate leaks and improve reliability by reducing the leak path and connections by up to 15%. It ensures all critical fittings are secured with O-ring face seals in an almost distortion-free manner. The high-tech Xe-Series controller for fixed speed drives (Xe 50) and variable speed drives (Xe 70) feature an easy to use interface with a high resolution colour display, satisfying all the requirements of a compressor orientated business.
“These are only some of the technological improvements to this range,” says Rob Hall, country leader for Ingersoll Rand South Africa. “We also provide a fully integrated sensor and control system to monitor differential pressure and warn users when the air, coolant and separation filtration elements are close to the end of their lives. A brand new thermal valve that maintains a constant oil temperature to keep water from condensing in low flow and low ambient conditions is also used in the compressors; and a highly efficient and stable gear driven system increases compressor service life.
“All our products and solutions, right across our diverse ranges, are designed and built to enhance our customers’ energy efficiency, productivity and ultimately their operations,” Hall concludes.
Ingersoll Rand is a specialist in compressed air systems, power tools and fluid and materials handling equipment. Its products range from complete air compressor systems to tools, ARO pumps and material handling systems.
