ToroSoleil, LLC, was founded on the principle of innovation. With over 35 years of industry experience, we have witnessed the status quo of onsite gas fractionation with its benefits and misfortunes. Taking an open perspective, ToroSoleil has approached seemingly easily solvable problems with packaged oxygen generation equipment. With this in mind, the Sentinel PSAG was born. The end result is a trusted product with the potential to save our customers tens of thousands of dollars or more in equipment damage and will virtually eliminate unscheduled downtime.
