Rotary Screw Air Compressors Nirvana

By matching a standard variable speed inverter with a HYBRID PERMANENT MAGNET® motor, Ingersoll Rand is first-to-market with a true variable speed drive compressors. In both single and two-stage, the Nirvana rotary screw air compressors has fewer rotating parts than any other air compressor in its class. And the Hybrid Permanent Magnet motor driving the Nirvana compressors raises the standard on compressor reliability to an unequaled level. There are no motor bearings in the HPM® motor. And since the HPM motor directly drives the compressors, there are no gears, pulleys, belts, couplings or motor shaft seals to wear out, leak or need replacing. And there is nothing to get out of alignment. Coupled with Ingersoll Rand's time-proven, reliable airend, Nirvana is as low-maintenance as an air compressors can get.

Comparison of Rotary Capacity Controls Nirvana rotary screw air compressors deliver constant pressure and maximum efficiency at any capacity. The Nirvana motor turns off at 25% capacity and automatically turns on when air pressure decays Nirvana rotary screw air compressors deliver constant pressure and maximum efficiency at any capacity.

• The typical compressors operates at an average of 70% load.
• The Nirvana VSD decreases the overall energy cost 22% 30%, compared to a fixed speed rotary air compressors.
• The Nirvana VSD decreases the overall energy cost 22% 30%, compared to a fixed speed rotary air compressor.
• Maximum energy savings is achieved by the Nirvana two-stage yielding 33%-41% savings.

Rotary comparison at 70% average volume capacity; 4,000 hours per year; ,05/kWh Traditional purchase decision factors represent only 20% of the cost to own and operate a rotary screw compressors while 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 COMPRESSORS
