Oil-free Compressed Air System Solution Nirvana37-160kW

• Nirvana oil-free air compressor with real VSD function 

Nirvana oil-free air compressor can provide high quality oil-free compressed air supported with unmatched reliability in the market. Ingersoll Rand has once again successfully developed and released to market an oil-free air compressor with real VSD variable-frequency drive system by right of its unique design combining hybrid permanent magnet motor with innovative modular converter. Compared with other types of oil-free screw air compressors, Nirvana oil-free air compressor has much less rotating parts, and thus guarantees its extremely high reliability as driven by hybrid permanent magnet motor.

• Newly upgraded hybrid permanent magnet motor with no bearings or wear parts

Ingersoll Rand's unique VSD variable-frequency drive system enables the air compressor to ideally maintain high efficiency under a range of operating conditions. While starting the motor of a conventional air compressor may consume a lot of energy withthe starting current usually being up to 8 times of the normal operating current at full load, the hybrid permanent magnet motor of Nirvana guarantees that the starting current is less than 100% of the load current, and thus eliminates the impact of air compressor start on the grid and saves energy.

Nirvana requires no unloading, but simply lowers the screw speed to accommodate any changes in displacement. Nirvana adopts a shutdown mode simpler than the unloading mode of other air compressors. Also, Ingersoll Rand's unique super coating and hybrid permanent magnet motor makes Nirvana oil-free screw air compressor to be reliable, and save at least 30% energy over the conventional oil-free screw air compressors.
