Nirvana 190-225 kW rotary air compressors offer the very best of time-proven designs and technologies with new, advanced features that ensure the highest levels of reliability, efficiency and productivity available in their class today. Nirvana's two-stage airend provides a combined energy savings of 33-41%!

 

 

Features

Reliability

• Premium Two-Stage Airend

  - Delivers 11-15% more air than a single-stage compressor with no additional power 
  - Lower compression ratio in each stage reduces bearing 
  - loads and increases airend life 
  - High-quality duplex tapered roller bearings 
  - Precision-machined rotors ensure unmatched rotor profile accuracy 
  - Ingersoll Rand's unique coolant curtain

Efficiency

• HPM Motor

  - Our high-efficiency HPM motor produces more air across a wider operating range with no increase in power consumption 
  - Decreases energy costs by 22-30% over a fixed speed compressor 
  - 95% efficiency throughout the entire speed range 
  - Four times as many poles and generates 33% more magnetic flux 
  - Two times the air gap for increased cooling enabling unlimited starts and stops 
  - Maintenance-free motor design

Productivity

• On-board drive diagnostics are easy to read on our Intellisys^TM microprocessor controller
• Controlled soft start eliminates current surges
• Coolant conditioner for optimum thermal discharge and performance
• Leak free SAE O-rings
• Long-life lubricant lasts up to 8,000 hours between changes

Global Service

• No matter where you are, Ingersoll Rand is committed to providing you with the service you need. Our worldwide network of certified, factory trained technicians and engineers are a phone call away, ready to support you with innovative and cost-effective service solutions that will keep you running at peak performance.

Small Footprint

• The new Ingersoll Rand 90-160kW Marine air compressors' width has been reduced by 28%, featuring now the competitive dimensions of 95 cm width and 295 cm length. The reduced dimensions will not only decrease your footprint usage, you will equally achieve time efficiency thanks to easier and faster installation.

Higher Flow, Greater Efficiency

• Two specific pressure versions - 6 and 8 barg - have been designed to provide higher flow rates. Combined with an increased motor efficiency, this compressor achieves a flow rate increased by 15% for bulk handling applications.

Reliability and Robustness

• The V-Shield Technology improves the reliability of this compressor through repeatable leak-free connections and superior VITON? elastomeric seals. Due to less connection points, the potential leak paths were reduced by 15%. The Ingersoll Rand 90-160kW Marine compressors are engineered to operate under high ambient conditions with up to 50°C.

Easy and Limited Maintenance

• Innovations, such as the coolant filter's re-usable canister and the separator elements' swing out lid ensure a quick and easy maintenance. Extended lifetime of the elements allows an increased interval of required maintenance.

• Ultra Coolant 
  Designed specifically for rotary screw air compressors, Ultra Coolant minimizes maintenance costs by extending the operating life of the compressor and maximizing the time between changes: 8,000 hours or 2 years.
• Digital Control System 
  Delivered capacity of the compressor is regulated by the Intellisys microprocessor controller and regulator. The intuitive controller provides all the information you need at the touch of a button. You can rest assured that your compressor will be under reliable control needing minimum maintenance.
• Higher Ambient Rating 
  Rated to operate continuously at high ambient temperatures of 115oF (46oC). This means fewer nuisance shutdowns due to summer heat or reduced susceptibility to operating in dirty conditions.
• Advanced Air-end Design 
  At the heart of the compressor is our conservatively loaded, rugged and highly reliable air-end which is close coupled to an integrated drive system. This gear drive arrangement eliminates the need for couplings and is known throughout the industry for its trouble-free operation with minimal maintenance.
