Efficiency is Everything at Ingersoll Rand

Efficiency is everything at Ingersoll Rand. The $14 billion global industrial manufacturing giant has been a leader in compressed air technologies for 145+ years largely because of its relentless focus on creating comfortable, sustainable, and efficient environments. When you’re that good, the bar to get better is high.

The engineers at Ingersoll Rand recognized a key efficiency opportunity to move beyond standard open impeller designs to a shrouded impeller design. Open impeller designs require clearance between the impeller and stationary inlet. The challenge is that compression gas recirculates in that clearance space creating a slip loss. This results in reduced efficiency and performance. Shrouded impellers eliminate these slip losses, thereby improving the overall performance of the total compressor package.
