Exceptional Reliability
Introducing Nirvana-
A True Variable-Speed Drive Compressor Now
Available in Single- and Two-Stage.
By matching a standard variable-speed inverter with A Hybrid Permanent Magnet (HPM) motor, Ingersoll-Rand is First-to-market with a true variable-speed drive compressor. In both single- and two-stage, the Nirvana compressor has fewer rotating parts than any other air compressor in its class.
HPM motor has no bearings, thus raising the standard on compressor reliability to an unequalled level.
Since the HPM motor directly drives the compressor, there are no pulleys, belts, couplings or motor shaft seals that would wear out, leak or need replacing.
Coupled with Ingersoll-Rand’s time-proven, reliable airend, Nirvana is as low-maintenance as an air compressor can get.
Field-Replaceable Motor Stator Provides Dramatically Improved Uptime
Nirvana’s contact-cooled high-efficiency HPM motor has virtually no wearing parts. Should the motor be subjected to a catastrophic electrical surge or other electrothermal event that damages one or more of the motor coils, the stator is quickly and easily replaced in the field by authorized technicians. The Nirvana stator exchange program provides
Quick, convenient turnaround;
Less expense than a motor rewind.
Integral Design, Fewer Parts and Fewer Connections Help Eliminate Trouble Spots, Leaks and Failures
Nirvana’s leak-free design uses a single-point connection between airend and separator. This eliminates troublesome compressor piping and leak-prone connections that cause downtime and drive up operating and repair costs.
Time-Proven Quality Airend and Inverter
Not everything in the Nirvana compressor is brand new. At the core of all Nirvana compressors is Ingersoll-Rand’s rugged, reliable single- and two-stage airends.
Ingersoll-Rand’s advanced airend design is known everywhere for trouble-free operation and minimal maintenance.
The Variable Frequency Drive(VFD) uses a standard inverter that is well recognized for providing dependable service in manufacturing operations all over the world.
Energy Efficiency
Nirvana. Maximum Efficiency at Virtually And Load
At full load, the new Nirvana compressor can produce the most air using the least energy. Ingersoll-Rand will guarantee these efficiencies down to loads as low as 25%.
By comparison, a conventional fixed-speed air compressor can produce extreme pressure fluctuations, greatly reducing efficiency whenever the compressor operates outside its optimum performance range.
Using a frequency inverter and the HPM motor, Nirvana compressors-
Provide the only true variable-speed drive (VSD);
Deliver air at a constant pressure, regardless of demand, at maximum efficiency;
Achieve constant pressure and maximum efficiency across their entire operating range, from 100% loaded down to as little as 25% loaded.
Traditional purchase decision factors represent only 20% of the cost to own and operate a rotary screw compressor. Energy represents 80% of the life cycle cost. Only Nirvana will save at least 28% of the energy cost over its life.
Nirvana Will Reduce the Total Life Cycle Cost to Own and Operate an Air Compressor
Ingersoll-Rand’s exclusive VSD makes possible a range of operating characteristics that produce this unequaled energy efficiency.
In a conventional air compressor, starting up the drive motor creates an enormous energy draw, which can be as much as 800% of the full load normal running current. Nirvana’s HPM motor and drive system limits the in-rush current to less than 100%.
The significant decrease in starting amp requirements minimizes peak charges, leading to a lower energy bill.
Unlike conventional on-line/off-line air compressors, the Nirvana sump does not blowdown. Instead, Nirvana compressors simply reduce speed and volume to meet demand.
Rather than run unloaded, a Nirvana compressor simply shuts off.
Nirvana compressors allow unlimited starts per hour with no decrease in motor life; therefore, energy savings are tremendous.
Transcendent Technology
Nirvana.
More air. Wider range. More efficient.
Competitors attempt to achieve variable speeds using an inverter rigged to a conventional induction motor compressor drive train. But they end up using the same power to produce 10%-15% less air. Whether in single- or two-stage configuration, the double-efficient Nirvana compressors-
Produce more air across a wider operating range with no increase in power consumption;
Run at 95% efficiency at start-up vs. the competitions’ 90%, and maintain 95% efficiency through the entire speed range.
Nirvana’s more compact, doubly efficient single- and two-stage airend and HPM motor assembly each deliver both increased capacity and greater efficiency.
Unequalled Performance
Nirvana Two-Stage Beats the Performance of Any Other VFD Compressor at Full or Part Load
The typical compressor operates at an average of 70% load.
The Nirvana VSD decreases the overall energy cost 22%-30% compared to a fixed speed rotary air compressor.
The Nirvana two-stage produces approximately 11%-15% more air than a single-stage air compressor.
Maximum energy saving is achieved by the Nirvana two-stage yielding 33%-41% savings.
Nirvana’s Coolant Conditioner Allows the Compressor to Run at Constant Package Discharge Temperature
The Nirvana Coolant Conditioner matches the performance of the cooling system to the performance of the compressor, maximizes bearing life, lowers energy cost and keeps compressor noise levels to a whisper.
Sounds levels are as low as 59dB(A) and 67dB(A) at typical conditions.
The VFD on the coolant circuit eliminates any chance of moisture gathering in the coolant system. Competitive variable-frequency drive compressors will have a buildup of moisture in the coolant at partial loads, shortening bearing life.
Nirvana’s Coolant Conditioner manages to the optimum compressor coolant temperature, depending on the system load and ambient conditions.
