Ingersoll Rand R-Series 90-110 kW rotary screw air compressors

The Ingersoll Rand R-Series 90-110 kW rotary screw air compressors have an integrated, intelligent system, called Progressive Adaptive Control (PAC), that continuously monitors key operating parameters and adapts to prevent unexpected downtime. For example, should the filtration system start to clog or foul on a variable speed unit, the system will immediately display a real-time warning and maintenance indicator. Unlike conventional compressor controls, it won’t shut down the compressor should the situation worsen. Instead, it reduces the airflow to prevent overloading the compressor cooling system.

The series is available in four options to suit the load profile required. The fixed speed has single- or two-stage airends and can provide up to 15% improved efficiency. For applications with significant variation in air demand, the variable speed is also available with single- and two-stage airends and is driven by the Nirvana Hybrid Permanent Magnet (HPM) motor. Typically, the Nirvana HPM motor claims to save up to 35% in power costs while the two-stage airend can offer a further 15% reduction in power costs.
