Small rotary compressors with enhanced reliability
1st Quarter 2015
Pneumatic systems & components
Ingersoll Rand, a global leader in compressed air systems and services, power tools, fluid and material handling equipment, has extended its R-Series line of compressed air solutions to include small rotary compressors with V-Shield technology to reduce leaks and improve reliability.
Built on a common platform, the new R-Series 5-11 kW compressors are available in 5-11 kW, with flows of 114 to 98 m³/hr and pressures up to 14 bar on fixed speed units and 10 bar on variable speed drives.
“The compact design of the R-Series makes it the ideal workplace compressor with a 20% reduction in footprint and sound levels,” says Davor Horvat, product manager for contact-cooled machines at Ingersoll Rand in Europe, Middle East and Africa.
With the application of V-Shield technology, the leak path and connections on the R-Series compressors have been reduced by more than 15%. V-shield technology ensures all critical fittings are secured with O-ring face seals using a method that is nearly free from distortion. Leaks are virtually eliminated and performance isn’t sacrificed, regardless of how many reconnections are made. Leaks are also reduced by the use of polytetrafluoroethylene (PTFE) braided, stainless steel hoses for all oil-carrying lines.
Other advancements on the R-Series 5-11 kW include totally enclosed fan cooled (TEFC) motors that have a premium IE3 efficiency; a simple design and fewer components, reducing maintenance; large, convenient electronic controls, and a digital output display that comes standard to support easier programming and operation.
R-Series fixed speed compressors come standard with tri-voltage motors that adapt to the supply voltage, while variable speed motors come in multiple voltage options, allowing for more flexibility when configuring the system. An improved, leak-free, next-generation air-end features an integrated separation system to optimise air and oil separation for peak air quality.
All R-Series units are available as fixed and variable speed units that can be configured with integrated dryers as a Total Air System (TAS). Each TAS unit comes with high-performance dryers, a three-in-one heat exchanger and an independent fan circuit to generate dry, clean air consistently.
“When customers select our Total Air System configuration, the R-Series from Ingersoll Rand is a complete plug-and-play solution that, as a standard offering, generates the cleanest, driest compressed air right out of the box,” adds Horvat. An innovative new design vertically stacks the drive components of the R-Series 5-11 kW, reducing the equipment’s footprint by 20% and providing easier access to the components when maintenance and service are necessary. To further optimise its performance in limited workspaces, the drive components are mounted on an Ingersoll Rand vibration isolation system, reducing noise pollution and vibration.
