Expanded Rotary Screw Line
/Ingersoll Rand has expanded its contact-cooled rotary screw air compressor line with the introduction of the R-Series 55-75 kW / 75-100 hp range. This new range is available in fixed speed and Nirvana variable speed drive at capacities of up to 3.23-13.56 m3/min / 114-479 cfm.
Robert Horneman, global portfolio manager for Ingersoll Rand, stated: “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”.
The new range of compressors is equipped with the Xe-Series controller and a high resolution LCD screen. The display provides immediate and intuitive access to all vital compressor data and settings. The controller allows access and remote control of the compressor from any PC, tablet or smartphone. The controller is even able to send automatic email notifications of trips and warnings.
The integrated Total Air System (TAS) dryer and filtration option provides clean, dry air in one package. This minimizes installation costs and footprint and allows 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, which delivers ISO Class 1-4-2 quality air. The TAS option utilizes a patented 3-in-1 heat exchanger, which achieves improved energy efficiency and lower operating cost than traditional stand-alone dryers.
In addition to the new Xe-Series controller and TAS option, the advanced features introduced with the larger 90-160 kW / 125-200 hp range: PACTM protection, V-ShieldTM technology, and sequential cooling, are present in the 55-75 kW R-Series range. Progressive Adaptive ControlTM (PAC) protection is an integrated, intelligent system. It monitors filtration, ambient temperature and other parameters, and adapts the operation of the compressor to reduce energy consumption, lower noise, and increase uptime. V-Shield technology is a superior configuration that eliminates possible leak paths by using stainless steel pipes, durable metal-flex hoses and a vibration isolation system. Sequential cooling utilizes a centrifugal blower that consumes less energy and operates much more quietly than traditional cooling fans do.
R-Series compressors are designed to require less maintenance and to be easy to service. The amount of time required to service and maintain the compressors has been significantly reduced by the use of swing out separator covers, longer life consumables, easy-access hinged doors, single side maintenance access and slide out coolers.
New Energy Efficient HOC Dryers
/Ingersoll Rand has presented its new green lineup of heat of compression dryers (HOC), which use an energy efficient method to treat the compressed air.
The new HOC dryers not only offer energy efficiency, but also flexibility and reliability in a low-profile form. Wasted heat is converted into energy by the dryers, concluding in dry, oil free air that costs a fraction of mainstream desiccant dryers.
Clean, dry air is essential for an effective and productive compressed air system. This high-tech, low energy solution is far less expensive to operate than alternative traditional desiccant dryers without losing out on productivity and efficiency, said Christopher Ursillo, marketing manager for air treatment products at Ingersoll Rand. HOC dryers are a great alternative to traditional desiccant dryers, delivering instrument quality air while making use of waste heat from the air compressor.
In order to quantify the HOC’s energy efficiency, you can compare the estimated cost of operating a traditional 1,000 scfm desiccant dryer operating at 8,700 hours a year at $.10/kWh to a comparable HOC dryer. Totaling up the operating costs of electricity and compressed air for purge requirements, the heatless desiccant dryer costs $24,000 yearly to run, and the blower purge desiccant dryer costs $18,000. In the same conditions, Ingersoll Rand’s HOC dryer costs $120 yearly to operate.
No-loss drains that prohibit the waste of compressed air are just one of the featured components of Ingersoll Rand’s HOC dryers. These drains feature a low-pressure drop design that allows the air compressors to run at a lower pressure, thereby conserving energy. Other unique components of the HOC dryer’s drain include stainless steel heat exchangers that provide optimum performance even in the worst conditions, and guaranteed removal of condensation via its automatic drain bypass feature.
The low profile form of the HOC dryers mean that they can be installed in many areas, including those with low overhead clearance. Ingersoll Rand HOC’s low profile design also allows for service personnel to easily service dryers when necessary. The HOC is unique in its class as it was designed to accommodate the use of multiple compressors, allowing its footprint to be reduced as well as installation costs.
