Power Supply Industries

PSI was founded in 1983 by Jack Bertelsmeyer and Curt Hertel. Since then, it has grown to over 30 employees and 3 locations. PSI has always been and will always be a full service compressor distributor.

Over the years, PSI has become the Midwest leader in providing efficient and reliable compressed air systems, service, and installation. Three locations in Missouri and Illinois allow timely service and parts deliveries. PSI has strong relationships with customers as diverse as Anheuser Busch, Boeing, US Steel, Toyota, Continental General Tire, and Mississippi Lime to name a few.

We invest heavily in our employees through ongoing training and continual improvements. PSI employees are the single biggest asset to the company, and they are treated as such. This, combined with engineering experience and a technical understanding of our products, allows PSI to provide unmatched service for our customers.

The result is typically a dramatic reduction of your monthly electric bill and usage.
