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

Controlled soft start eliminates current surges

Coolant conditioner for optimum thermal discharge and performance

Leak free SAE O-rings

Long-life lubricant: 8,000 hours between changes

Looking for a rugged and reliable air compressor? Then look no further than Ingersoll Rand's SSR/M Series of rotary air compressors. With our integral gear drivetrain, Intellisys control system, and 8000 hour coolant, this is a compressor that you can count on for years to come.

Features

Digital Control System

Capacity control of the compressor is regulated by the Intellisys microprocessor controller and an electric stepper motor. Since there are no pressure switches to drift and very few moving parts, the SSR/M can maintain plant air pressure without constant maintenance.

Higher Ambient Rating

The SSR/M operates easily in ambient temperatures up to 115° F (46° C), even the motor. This means fewer nuisance shutdowns due to summer heat or dirty coolers.

Advanced Airend Design

At the heart of the SSR/M is our time-proven drive system. This integral gear arrangement is known throughout the industry for its trouble-free operation with minimal maintenance.

Ultra Coolant

Designed specifically for rotary screw air compressors, Ultra Coolant minimizes maintenance costs by maximizing the time between changes: 8,000 hours or 2 years.

Looking for a highly energy efficient and reliable air compressor? Then look no further than Ingersoll Rand's SSR/M 2-Stage Series of compressors. With our integral gear drive system, digital control system, and 8,000 hour coolant, the SSR/M 2-Stage is a compressor that you can count on for years to come.

Reduced Bearing Load

A lower compression ratio in each stage leads to reduced bearing loads and longer airend life.

Energy Efficient Airend

At the heart of the compressor is our time-proven 2-stage airend. By compressing the air in two steps instead of one, energy savings of up to 15% are realized.

Digital Control System

Capacity control of the compressor is regulated by the Intellisys microprocessor controller and an electric stepper motor. Since there are no pressure switches to adjust and very few moving parts, the SSR/M 2-Stage can maintain plant air pressure without constant attention.
