New 200–250kW rotary screw air compressors

Ingersoll Rand next generation compressors decrease energy costs by up to €40,000 for large manufacturing facilities

Ingersoll Rand, compression technologies and services provider, has introduced new models to its line of Next Generation R-Series oil-flooded rotary screw air compressors, which provide a more energy-efficient solution for customers with high capacity air requirements.

The new fixed-speed models are 10% more efficient compared to legacy products, while the variable speed option is up to 35% more efficient compared to the industry average.

According to internal testing, efficiency and design improvements on some of the high capacity compressors deliver up to a €40,000 energy cost savings throughout a two-year period per compressor compared to previous models.

Standard features

The RS200 to RS250 models are available with the new, state-of-the-art single-stage airend, or the two-stage airend that increases airflow by up to 16%.

According to the company, this two-stage airend is the most efficient airend currently available on the market.

Each compressor comes standard with Progressive Adaptive Control (PAC) Protection, V-Shield technology, floating coolers and Ultra EL Lubricant.

Progressive Adaptive Control

PAC Protection is a unique algorithm developed by Ingersoll Rand and is integrated in the controls system within each compressor.

The system monitors key performance parameters for when consumable parts are nearing the end of their life, or if operating temperatures are reaching design limits. In these situations, the controls adjust the parameters to keep the machine running without overloading the motor, preventing unnecessary shutdown.

V-Shield and floating cooling system

V-Shield technology safeguards all critical fittings by securing them with o-ring face seals in a method that is largely free from distortion. Leaks are virtually eliminated, meaning performance isn’t sacrificed, regardless of how many reconnections are made.

The floating cooling system contains heat exchangers with finger-tight connections so they can expand and contract as needed. This new design improves overall system reliability, because welded connections reduce the ability for heat exchangers to expand and contract, which is the number one reason they fail.

Other features

Ultra EL is formulated to last up to 16,000 hours, twice as long as other rotary lubricants.

All Next Generation R-Series air compressors are equipped with Xe-series controllers, which allow intuitive control of the compressed air system.

The Xe145 controller has built-in performance analysis and graphical trending, as well as built-in sequencing for up to four compressors.
