Product Innovation

ERI's PX devices, which feature only one moving part, are the most elegant approach to high-efficiency energy recovery available today. The heart of the PX is an aluminum oxide rotor, floating in an almost frictionless hydrodynamic bearing.

Oil & Gas Applications

Gas processing plants require intensive amounts of energy, similar to desalination. ERI can help solve these same challenges in the oil and gas markets. ERI solutions offer the highest efficiency, durability and energy savings.
