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%!

 

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 compressors
- 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 IntellisysTM microprocessor controller
