Our History

In 1985 Gary Charles, a former Hunt Engine and Equipment employee, started Power Systems Specialists as a manufacturers’ representative to handle the growing demand for alternators and related components in Louisiana and Mississippi. Working with both engine packagers and engineering firms, he grew the business through a commitment to meeting the high and specific demands of the petroleum and marine markets.

In 1988, Lee Dupont, a former George Engine Company engineer, started Dupont Engineering as a manufacturers’ representative with a focus on mechanical equipment relating to reciprocating engines – specifically heat transfer equipment. Dupont Engineering grew to be a leader in providing quality equipment and services while meeting customers’ budget and specification requirements.

In 2009, Gary and Lee merged the companies under the name Power Systems Specialists, with a focus on a combined strategy of providing electrical and mechanical components for the marine, petroleum, and commercial markets, with an emphasis on matching the correct products to any application.
